MIPT patents graphene biosensors in the USA
The Moscow Institute of Physics and Technology (MIPT) is patenting biosensor chips based on graphene, graphene oxide and carbon nanotubes in the United States, which will increase the accuracy of the analysis of biochemical reactions and accelerate the search for new vital medicines, the MIPT press service reports.
The American Patent Office has published an application for patent No. 20150301039, filed by MIPT in May of this year. The application describes "a biological sensor and a method of creating a biological sensor" (Biological Sensor and a Method of the Production of Biological Sensor – VM). In Russia, this development is already protected by patent No. 2527699 with priority dated February 20, 2013.
The key feature of the sensor is the use of a thin film of several layers of graphene or graphene oxide as a binding layer. Graphene is the first truly two-dimensional crystal, experimentally obtained in laboratory conditions, with unique physicochemical properties.
In 2010, MIPT graduates Andrey Geim and Konstantin Novoselov were awarded the Nobel Prize in Physics for "advanced experiments with a two–dimensional material - graphene". Currently, there is an explosive growth of research aimed at finding commercial applications for graphene and other two-dimensional materials. Within the framework of only one European project, The Graphene Flagship, funding in the amount of 1 billion euros has been allocated for these purposes.
Tagless biosensors have appeared relatively recently in the laboratories of biochemists and pharmacists, greatly facilitating and simplifying their work. These sensors can detect small concentrations of biologically important molecular objects (RNA, DNA, proteins, including antibodies and antigens, viruses and bacteria) and investigate their chemical properties. Unlike other biochemical methods, it is not necessary to use fluorescent or radioactive markers for biosensors to work, which simplifies the experiment, and also reduces the likelihood of obtaining erroneous data associated with the effect of labels on the passage of biochemical reactions. The main areas of application of this technology are pharmaceutical and scientific research, medical diagnostics, food quality control and toxin detection.
