MIPT researchers patent graphene biosensors that may accelerate development of novel drugs

The US Patent Office has recently published the patent application (no. US 2015/0301039), which was filed by the MIPT in May this year and is titled Biological Sensor and a Method of the Production of Biological Sensor. In Russia, this development is already protected by the patent No. 2527699 with a priority date of February 20, 2013. The key feature of the sensor is the use of a linking layer for biomolecule immobilization comprising a thin film of graphene or graphene oxide.

Novel graphene oxide-based biosensor may speed up development of new drugs against HIV, cancer

Longing to find a cure for cancer, HIV and other yet incurable diseases, researchers have already tried out hundreds of drugs, each requiring preclinical and clinical testing with live subjects. How many chemical agents more to try? Moving at such rate, will we find the cure during our lifetime? One of the easiest ways to speed up the drug development process is to simply perform it outside of the living body (e.g., by watching the substances react with the smallest pieces of live tissue and thus quickly predicting the overall effect it will make to the body when inside).

MIPT researchers develop ultrasensitive nanomechanical sensor to identify tumor markers

Two young researchers working at the MIPT Laboratory of Nanooptics and Plasmonics, Dmitry Fedyanin and Yury Stebunov, have developed an ultracompact highly sensitive nanomechanical sensor for analyzing the chemical composition of substances and detecting biological objects, such as viral disease markers, which appear when the immune system responds to incurable or hard-to-cure diseases, including HIV, hepatitis, herpes, and many others.

Using a nanotech microchip to diagnose type 1 diabetes: an interview with Dr. Brian Feldman, Stanford School of Medicine

The most common form of diabetes is sometimes referred to as metabolic diabetes, which is the diabetes most people are very familiar with, type 2 diabetes. This form of diabetes is most prevalent in people that are overweight or obese. Historically, it has been confined to adults or older patients but it has been on the rise as the global obesity problem has continued to worsen.

Brown University researchers develop new biochip sensor to measure glucose levels in saliva

Researchers from Brown University have developed a new biochip sensor that can selectively measure concentrations of glucose in a complex solution similar to human saliva. The advance is an important step toward a device that would enable people with diabetes to test their glucose levels without drawing blood.

Researchers exploit plasmonic nanoparticles to kill tumour cells

If you put your hand over a switched-on torch in the dark, it appears to glow red. This is because long-wavelength red light beams penetrate human tissue more effectively than short-wavelength blue light.

Solder for laser welding of tissue produces stronger seals during intestinal surgery

A new "solder" for laser welding of tissue during surgical operations has the potential to produce stronger seals and expand use of this alternative to conventional sutures and stapling in intestinal surgery, scientists are reporting. Their study, which involves use of a gold-based solder, or sealing material, appears in the journal ACS Nano.
