MSU chemists work on biosensors for diagnostic wearables
10 Apr '17
Chemists at the Moscow Lomonosov State University (MSU) have come up with a range of biosensors based on what’s known as Prussian Blue (PB). The MSU website quoted Elena Karpova, one of the key developers and a postgraduate at the university’s Department of Chemistry, as saying that “the new biosensors could be used in an array of wearable devices, which are getting so popular these days, for noninvasive monitoring of glucose and lactic acid.”
The results of the research have been recently published in English in Journal of the Electrochemical Society.
According to Ms. Karpova, it’s a first generation of PB-based biosensors stabilized with nickel hexacyanoferrate (NiHCF); labile lactate oxidase was also used in the process. The project is said to demonstrate twice the operational stability of PB-NiHCF bilayer based biosensors and labile lactate oxidase compared to non-modified Prussian Blue based biosensors.
