Gene sequencing is a new gene detection technology, which simply means to display the sequence of base ATGC in DNA/RNA molecules.Gene sequencing technology can be used to analyze and determine the full sequence of genes from blood or saliva, so as to target individual genes for prevention and treatment in advance. In 1977, Walter Gilbert and Frederick Sanger established DNA sequencing technology and won the Nobel Prize in chemistry in 1980.From there, the technology that will dominate the future of the life sciences is widely used in research. Over the past 40 years or so, gene sequencing has undergone many technological The first generation of gene sequencing technology (Sanger sequencing) is based on the sequencing principle of Sanger dideoxy termination method, combined with fluorescence labeling and capillary array electrophoresis technology to realize the automation of sequencing. The basic method is chain termination or degradation method.The method was then converted to fluorescent nucleotide labeling, capillary electrophoresis differentiation and laser detection, thus realizing the first generation of automated sequencing method. The second-generation sequencing (NGS) achieves high-throughput sequencing at the expense of reading length, and the sequence of hundreds of thousands to millions of nucleic acid molecules can be obtained simultaneously in one operation. The first generation of sequencing is synthetic termination sequencing, while the second generation of sequencing is pioneering in the introduction of reversible termination terminals, so as to achieve simultaneous synthesis and sequencing.The DNA is sequenced by a laser that excites a fluorescent signal during DNA replication, scanning it for special markers (commonly known as fluorescent molecular markers) carried by newly added bases. The second generation sequencing with high flux, low cost, short time sequencing and other advantages, quickly occupied the dominant position in sequencing in the global market, its application areas including noninvasive prenatal testing (NIPT), pre-implantation genetic diagnosis (PGD/PGS)/screening, genetic disease diagnosis, tumor diagnosis and individualized treatment, gene detection, pathogenic microorganism, etc. The third generation of DNA sequencing technology mainly includes three kinds: Helico Bioscience Single molecule sequencing technology, Pacific Bioscience Single molecule Realtime (SMRT) sequencing technology and Oxford Nanopore Single molecule sequencing technology (real-time sequencing of "electrical signal" changes brought by Nanopore). Compared with the previous two generations of sequencing technology, its biggest feature is single molecule sequencing, which does not require PCR amplification and can theoretically determine the nucleic acid sequence of infinite length.Therefore, the third generation sequencing technology is also known as single molecule DNA sequencing, that is, the modern optical, polymer, nano technology and other means to distinguish the difference between the base signal principle, in order to achieve the purpose of direct reading sequence information.Without the use of biological or chemical reagents, costs can be further reduced. The biggest problem with third-generation sequencing is the high error rate (15-40%).However, errors are random and do not have the bias of sequencing errors like the second-generation sequencing technology. Therefore, multiple sequencing can be used to effectively correct errors. The ability to efficiently activate the fluorescence of the four chemical markers of DNA nucleotide (ACGT) by laser, and the ability to accurately distinguish the four fluorescent dyes, are crucial to gene sequencing.Therefore, the choice of laser will directly affect the accuracy and efficiency of sequencing. At present, common wavelengths in the gene sequencing market are: 488 nm blue laser, 514 nm green laser, 532 nm green laser, 577nm yellow laser, 639nm red laser, 660nm red laser, 690nm red laser... In the research and development and experiment of companies or universities, in addition to the requirements of optical parameters of lasers, more needs are "customized" solutions.Simple ones such as optical fiber transmission, spot shaping, more complex ones such as multi-wavelength synthesis, high consistency between multiple wavelengths and so on.

To memorize this milestone, we listed some applications in respect to our customers. 01Confocal Light Field Microscopy The institute of Neuroscence, Chinese Academy of Sciences, presents a new imaging method, confocal light field microscopy, to enable fast volumetric imaging deep into brain. They demonstrated the power of this method by recording whole brain calcium transients in freely swimming larval zebrafish and observed behaviorally correlated activities on single neurons during its prey capture. Furthermore, they captured neural activities and circulating blood cells over a volume ⌀ 800 μm x 150 μm at 70 Hz and up to 600 μm deep in the mice brain.

Periodical: IEEE Transactions on Biomedical Engineering · January 2020 DOI: 10.1109/TBME.2019.2963464, page 3 03 Photodynamic Therapy Antimicrobial photodynamic therapy (aPDT) leads to the generation of reactive oxygen species (ROS) that destroys bacterial cells in presence of a photosensitizer, visible light, and oxygen. Aligarh Muslim University has taken Enterococcus faEcalis and Streptococcus mutans as monospecies culture and their dualspecies culture biofilm. Antibacterial effect was evaluated by colony forming unit while antibiofilm action by crystal violet and congored binding assays. Finally they found that reactive oxygen species and singlet oxygen yield was found to be light dose dependent and antimicrobial photodynamic efficiency is directly related to the ROS production.

Periodical: Photodiagnosis and Photodynamic Therapy, 2019 - Elsevier 04 Nitrogen-vacancy Center Detection Electron spin resonance (ESR) spectroscopy has broad applications in physics, chemistry, and biology. However, the traditional zero-fifield ESR (ZF-ESR) method has been rarely used due to the low sensitivity and the requirement of much larger samples than conventional ESR. The University of Science and Technology of China presents a method for deploying ZF-ESR spectroscopy at the nanoscale by using a highly sensitive quantum sensor, the nitrogen vacancy center in diamond. This method opens the door to practical applications of ZF-ESR spectroscopy, such as investigation of the structure and polarity information in spin-modifified organic and biological systems. They use a CNI 532nm laser and their paper is published in Nature Communications.

FeaturesHere's a quick guide to pizza cook timing:   Thin Crust Pizza Dough Roll out dough very thin, around 1/8-inch thick Bake at 500°F (260°C) for 8-10 minutes, until crust is lightly browned   Medium Crust Pizza Dough Roll out dough to desired thickness, around 1/4 inch thick Bake at 475-500°F (245-260°C) for 10-15 minutes, until golden brown   Deep Dish Pizza Dough Press dough into an oiled deep dish pan to form a 1-1.5 inch thick crust up sides Bake at 400°F (205°C) for 20-30 minutes, until crust is golden and filling is bubbly    Timing is crucial for achieving the perfect pizza with a browned crust and well-cooked toppings. Follow these times to ensure your pizza is baked to perfection.   The Average Time to Cook a Pizza For most ovens, bake your pizza at a high temperature, between 400°F to 500°F. The cooking time typically ranges from:   Thin Crust Pizza Temperature: 500°F (260°C) Time: 8-10 minutes Bake until crust is lightly browned   Medium/Traditional Crust Pizza Temperature: 475-500°F (245-260°C) Time: 10-15 minutes Bake until golden brow   Deep Dish Pizza Temperature: 400-450°F (205-230°C) Time: 20-30 minutes Bake until crust is golden and filling is bubbly Cover edges with foil after 15 minutes to prevent over-browning   It's essential to preheat the oven for around 20 to 30 minutes before cooking to maintain a steady temperature throughout the baking process. The bake time can vary depending on factors like oven temperature, thickness of crust, and amount of toppings. It's recommended to watch the pizza closely towards the end of the bake time. Allow 5-10 minutes cooling time for deep dish pizza before slicing and serving.    Time Distribution for Cooking Pizza    Depending on your oven type and whether you're using a pizza stone, a baking sheet, or placing the pizza directly on the oven rack, the time distribution for pizza cooking may vary slightly. With a pizza stone: preheat the stone with the oven. Directly on the oven rack: ensure your pizza dough has enough structure to hold the toppings. On a baking sheet: it might slightly increase the required time due to less heat conductivity compared to a pizza stone.  Preparation Allow the pizza dough to come to room temperature and rest for 30 minutes before shaping. This allows the gluten to relax and makes the dough easier to shape. Preheat the oven as high as possible, ideally between 450-500°F. Allow at least 15-20 minutes for the oven to fully preheat before baking. If using a pizza stone, place it in the oven while preheating. The hot stone will help crisp the bottom crust.   Baking Time Bake the pizza for 8-15 minutes, depending on oven temperature and the thickness of the crust. The crust should be golden brown when done. The edges may brown faster than the center, so watch closely. For a thick-crusted pizza, a lower temp (around 400°F) and longer bake time (20-30 minutes) are needed to fully cook the center without over-browning the edges. Meat or extra cheese toppings will require a longer baking time, closer to 15 minutes.    Variables that impact cooking time are critical to achieving the perfect crust and well-cooked toppings. Your oven's temperature, along with the choice of toppings and type of pizza dough, plays pivotal roles in the outcome of your homemade pizza.   Here's what you need to consider:   Pizza Type: Fresh homemade pizzas typically bake quicker than frozen ones. Size: Smaller pizzas cook faster than larger ones. Crust Thickness: A thin crust bakes in a shorter time compared with a thick or deep-dish crust. Oven Temperature: A higher temperature shortens the baking time. Toppings and pizza sauce: Heavier toppings or extra sauce might need additional time to cook through.    The Best Temperature to Cook Pizza   For a classic medium-crust pizza, cooking at high temperatures ranging from 475°F to 500°F (245°C to 260°C) is ideal. These temperatures promote a browned, crispy crust. For thicker crusts, lower the heat slightly to around 400°F to 450°F (205°C to 230°C), extending the baking time to ensure the middle is cooked through without burning the crust.     The Baking Time Vary Based on the Ingredients Used      Thicker crusts and heftier toppings add to the cooking time. More moisture from pizza sauce or vegetables requires a couple of extra minutes.   Conversely, a thin-crust pizza with minimal toppings could be ready in about 10 minutes.   Using a pizza stone can reduce cooking time and improve crust texture, due to its heat retention and distribution properties. Always preheat the oven with the pizza stone inside. When the oven reaches the appropriate temperature, slide the pizza onto the stone using a pizza peel for best results. Using a baking sheet may increase the baking time slightly, as it does not conduct heat as effectively.  To determine if your pizza is cooked correctly, check the crust for a golden-brown color and ensure the cheese is evenly melted and bubbling. A properly baked pizza should exhibit these characteristics when the recommended oven temperature and baking time are followed.   Crust Thickness   Your pizza crust's thickness directly influences your baking time. For a thinner crust, a high temperature of around 500°F (260°C) for 8-10 minutes is often sufficient. In contrast, a thicker crust will require a slightly lower temperature and a longer bake time, typically 10-15 minutes, to ensure it's cooked all the way through without burning.   Using a pizza stone can help evenly distribute heat, providing a consistent baking surface that results in a crisper crust. Always preheat the pizza stone with the oven to ensure it’s at the right temperature before introducing your dough ball or frozen pizza.    Cheese Melt   The state of the cheese is a reliable indicator of doneness. 1.Even Melt: The cheese should be fully melted across the surface of the pizza, without any unmelted patches.2.Color: Look for a slightly golden hue, especially on raised areas where the cheese might bubble.3.Texture: It should be bubbly and potentially exhibit spots of light browning without being burnt.   If the pizza contains toppings, they should be cooked through and complement the melted cheese. Keep an eye on them, primarily when using toppings that can greatly affect the overall bake, like large amounts of moist vegetables or thick slices of meat.   Remember to adjust your baking time if your pizza is loaded with toppings, as this can increase the moisture content and require additional time. Always use a baking sheet or pizza peel to safely handle your pizza and preheat the oven to the desired temperature for an effective bake.  Why Does the Oven Need to Be So Hot?   A hot oven is key to replicating the environment of a professional pizza oven at home. High temperatures allow for the rapid rising of the dough ball, creating air pockets that lead to a light and airy pizza crust. This intense heat also ensures a delightfully brown and crispy base while melting the cheese to a perfect golden hue.   At what temperature and duration should homemade pizza be baked for best results?   For a balance of a crispy crust and evenly cooked toppings, bake your pizza at a temperature of around 475-500 degrees Fahrenheit for 10 to 15 minutes. Homemade pizzas generally require a high temperature for a shorter duration to emulate the environment of a professional pizza oven.   For a softer crust, how long should pizza be baked at 350 degrees Fahrenheit?   To achieve a softer crust, baking the pizza at 350 degrees Fahrenheit for about 20 to 25 minutes is advised. This lower temperature allows the pizza to cook through more slowly, resulting in a less crispy texture.   What is the recommended cooking time for pizza at a high temperature, such as 500 degrees Fahrenheit?   When baking pizza at 500 degrees Fahrenheit, aim for a cooking time of about 8 to 10 minutes. Such a high temperature creates a crisp crust and quickly melts the cheese, while still cooking the toppings thoroughly.   How do different oven temperatures, like 400 or 450 degrees Fahrenheit, affect pizza cooking times?   At 400°F, a thin-crust pizza takes 10-15 minutes to cook. At 450°F, the same thin crust can be done in 8-12 minutes. For a thick-crust pizza, it takes 18-25 minutes at 400°F and 14-20 minutes at 450°F. So when increasing the temperature by 50 degrees Fahrenheit, the cooking time can be reduced by 2-5 minutes depending on crust thickness.
