Mass Photometry

By Brian (Ruibo) Wu

In 2018, a group of researchers of the University of Oxford announced a new technological application they had developed, the mass photometry. It is a revolutionary way to analyze the mass of molecules by the methods they scatter light. The approach offers an insight into bioanalytics and biomolecules. 

Rather than the general mass spectroscopy that requires a strict vacuum environment, mass photometry allows the samples to stay in their original buffer solutions. And unlike chromatography that requires a large sample amount of sample, mass photometry can be achieved only by a few microliters of nanomolar concentration solutions. Researcher, Prof. Kucura, announced that the minute amount of light scattered by single molecules can be reliably detected and, more importantly, that it is directly correlated with molecular mass. 

Shortly after the discovery, the University of Oxford founded the company Refeyn to commercialize mass photometry. The first product, the Refeyn OneMP instruments went on the market in March of 2019 with the cost of roughly $150,000. Matthias Langhorst, the chief marketing officer of the company, says that “the Refeyn OneMP brings mass photometry into daily laboratory life. This unique instrument allows you to characterize your molecule of interest with unprecedented sensitivity, speed, and simplicity.” 

Even though mass photometry still has great untapped potential, it is widely used by laboratories all over the world and received numerous accounts of positive feedback. Anders Gunnarsson, the Associate Principal Scientist of Discovery Sciences, praises that they, “have been using the Refeyn OneMP mass photometer in our biophysics lab in Gothenburg for several months now. It has been invaluable in a number of studies, ranging from simple cases of clarifying the oligomeric states of drug targets to elucidating complex binding mechanisms of small molecules. I believe Refeyn’s mass photometry is a great piece of technology for any biophysics lab.”

  1. whoah this blog is fantastic i really like reading your posts. Keep up the good paintings! You realize, many individuals are searching around for this information, you could aid them greatly.

  2. Has anyone ever tried Dr. Fog’s Candy Series Eliquid?

  3. I discovered more interesting things on this weight-loss issue. A single issue is that good nutrition is very vital any time dieting. A huge reduction in junk food, sugary foods, fried foods, sweet foods, beef, and bright flour products could be necessary. Retaining wastes unwanted organisms, and wastes may prevent targets for losing fat. While a number of drugs briefly solve the situation, the bad side effects are not worth it, and they never offer more than a temporary solution. This can be a known proven fact that 95 of diet plans fail. Many thanks for sharing your ideas on this web site.

  4. Superb blog! Do you have any hints for aspiring writers? I’m planning to start my own blog soon but I’m a little lost on everything. Would you suggest starting with a free platform like WordPress or go for a paid option? There are so many options out there that I’m totally confused .. Any tips? Bless you!

  5. I believe that avoiding highly processed foods will be the first step to help lose weight. They might taste very good, but ready-made foods contain very little vitamins and minerals, making you eat more simply to have enough strength to get through the day. If you’re constantly having these foods, transferring to whole grains and other complex carbohydrates will aid you to have more electricity while ingesting less. Thanks alot : ) for your blog post.

  6. Pretty section of content. I just stumbled upon your weblog and in accession capital to assert that I get in fact enjoyed account your blog posts. Anyway I will be subscribing to your augment and even I achievement you access consistently quickly.

  7. I will also like to convey that most of those that find themselves without health insurance are typically students, self-employed and those that are unemployed. More than half from the uninsured are really under the age of Thirty five. They do not come to feel they are needing health insurance as they are young in addition to healthy. Their own income is typically spent on property, food, and entertainment. Some people that do represent the working class either complete or not professional are not made available insurance through their work so they go without as a result of rising tariff of health insurance in the usa. Thanks for the ideas you write about through your blog.

  8. Thanks a bunch for sharing this with all of us you really know what you are talking about! Bookmarked. Please also visit my site =). We could have a link exchange arrangement between us!

  9. Link exchange is nothing else however it is simply placing the other person’s website link on your page at suitable place and other person will also do similar for you.

  10. You made some first rate points there. I looked on the internet for the difficulty and located most individuals will associate with with your website.

  11. Thanks for discussing your ideas with this blog. In addition, a delusion regarding the lenders intentions whenever talking about home foreclosure is that the lender will not getreceive my installments. There is a degree of time in which the bank requires payments in some places. If you are far too deep inside hole, they should commonly demand that you pay that payment entirely. However, i am not saying that they will not take any sort of installments at all. When you and the loan company can be capable to work one thing out, this foreclosure approach may halt. However, if you ever continue to miss out on payments in the new approach, the foreclosed process can pick up where it left off.
