Released device for DNA tests with minimal material collection

On October 26, 2023, it became known about the development of a device capable of producing a DNA test with minimal collection of genetic material. The authors of the invention were scientists from the University of Massachusetts Amherst.

The new development will allow doctors to find genetic markers of diseases, since the new approach does not require laboratory analysis, which takes a lot of time and money. The technology works by allowing DNA oligomers to respond to an alternative energy source and "dance." By analyzing the frequency of oscillations of oligomers, scientists find the DNA element they need. The method requires a very small amount of DNA to work.

New DNA test device from University of Massachusetts Amherst

Finding DNA is the base for many diagnostic tests. Conventional approaches cannot find a small amount of DNA, and often require a significant increase in the DNA required for the test. This adds several additional steps, expensive reagents and expensive equipment to testing, plus everything, it takes a long time.

Finding DNA is the center of bioengineering. It is very important to be able to find DNA in low concentration with high sensitivity. And we developed this method, "Jingley Ping, one of the scientists involved in the study, commented on the news.

According to the authors of the development, its main advantage is speed and democracy. Usually, doctors send a sample to a laboratory, and there, depending on their speed and employment, the analysis can take 24 hours or more. Moreover, there are countries or remote regions where the nearest laboratory is very far away, and a local doctor can visit it once a month. If such doctors have the opportunity to quickly conduct tests themselves, they will be able to diagnose diseases faster, and therefore begin to treat them faster. Thus, survival in genetic diseases can increase.^[1]

In Moscow, began to produce express tests for the diagnosis of intestinal microflora children

The capital company has launched the production of medical tests that allow diagnosing the intestinal microbiota of children in three hours, Deputy Mayor of Moscow for Economic Policy and Property and Land Relations Vladimir Efimov said on February 15, 2023. Read more here.

DNA-Technology has developed tests to determine genetic diseases

The metropolitan company "DNA-Technology" has developed three types of tests to assess the risk of giving birth to a child with hereditary diseases. This was announced on January 27, 2023 by the head of the Department of Investment and Industrial Policy of Moscow, which is part of the Complex of Economic Policy and Property and Land Relations of the capital, Vladislav Ovchinsky.

2022: PreMama Genetic Test Submission to Determine Causes of Infertility

The company "System-BioTech" (part of AFK Sistema) has developed a genetic test PreMama, which is able to identify non-obvious causes of non-occurrence pregnancies and give recommendations for correcting the genetically embedded imbalance of metabolites in the body. In turn, this may contribute to the normalization of reproductive function and help get pregnant before the use of assisted technology. This was IVF Zdrav.Expert reported by representatives of Sistema-BioTech on December 8, 2022. More. here

2018: First home DNA test for breast cancer predisposition released

In early March 2018, the first genetic test for predisposition to breast cancer was announced, which can be used at home without going to a doctor. A product called DNA Collection Kit, developed by 23andMe, is designed to identify three mutations of the BRCA1 and BRCA2 genes associated with catfish at risk of developing not only breast cancer, but also ovarian or prostate cancer.
