New inexpensive biosensors for diagnosing various diseases have been invented

Scientists from the Atlantic University in Florida developed a platform of biosensors for remote detection and identification of treatment options for HIV, Escherichia coli, Staphylococcus and other bacteria. Using just one drop of blood, the biosensor produces clinically relevant indicators for detecting pathogens in the blood and plasma.

Biosensors for the diagnosis of various diseases
Thin, light and flexible materials can be manufactured and used without infrastructure and skilled personnel that will help to solve health problems in developing countries. countries. Using this technology, scientists have developed an application for phones that can calculate bacteria and diseases, and the data can be easily analyzed anywhere in the world.

Associate Professor of Electrical Engineering Waseem Asghar (Waseem Asghar), co-author of candidate of technical sciences and teacher at the Department of Biomedical Engineering at Harvard Medical School Hadi Shafiie (Hadi Shafiee), together with Utkan Demirci (Stanford's Utkan Demirci), published an article in which they told about cheap materials for biosensor platforms that detect several goals.

They were able to integrate cellulose, paper and flexible polyester film in creating new diagnostic tools that combine electrical and optical analysis methods. Scientists have managed to prove that new materials can be used in various areas of medical diagnostics. For example, to identify several biological targets selectively, accurately and repeatedly in various biological substances using antibodies. Existing platforms use colorimetric, fluorescent and electrochemical approaches that require the use of complex actions for decoding signals - expensive equipment and materials.

"The future of diagnosis and monitoring of health status is the use of a cell phone or portable devices for analysis a sample of saliva or blood, as well as constant monitoring of human health at any distance from it, "says Demirji, the author articles.

The materials used to develop new sensors can be disposed of without harm to humans and the surrounding world. Therefore, they provide a safe strategy for the development of available diagnostic tools, which is important when treatment of infectious diseases in developing countries with a limited level of laboratory infrastructure. The platforms can be adapted to any pathogens and various biological targets with known biomarkers.
