New Findings Reported from Zhejiang University Describe Advances in Biosensing

May 14, 2014

By a News Reporter-Staff News Editor at Biotech Week -- Current study results on Biosensing have been published. According to news reporting from Hangzhou, People's Republic of China, by NewsRx journalists, research stated, "Glucose sensors with long life span were fabricated and evaluated in 37 degrees C serum to imitate in vivo conditions. Polyaniline nanofibers were electrodeposited on sensor electrodes for excessive glucose oxidase immobilization to extend the lifetime of sensors."

The news correspondents obtained a quote from the research from Zhejiang University, "The sensitivity of sensors stored in 37 degrees C bovine serum was stable for 20 days without apparent descents, and still remained 45% of its initial value after 44 days. In order to further improve the life span of sensors, a degradable polymer film, poly lactic-co-glycolic acid (PLGA), was used as an out coating layer of glucose sensors. Results showed that the PLGA coated glucose sensors left 80% of its initial sensitivity after 44 days' storage in 37 degrees C bovine serum."

According to the news reporters, the research concluded: "The sensors could be potentially used as long-term implantable devices for real time monitoring of glucose levels."
