Electrospun poly(vinylidene fluoride)/poly(aminophenylboronic acid) composite nanofibrous membrane as a novel glucose sensor.

Electrospinning was used to prepare the nanofibrous membrane (NFM) of the composite comprising poly(vinylidene fluoride) and poly(aminophenylboronic acid) (PVdF/PAPBA-NFM). The PVdF/PAPBA-NFM displayed an excellent linear response to the detection of glucose for the concentration range of 1 to 15mM with a response time of less than 6s. Further experiments on amperometric sensing of glucose were performed in the presence of interferents such as uric acid, ascorbic acid, acetaminophen, fructose, mannose, etc. using PVdF/PAPBA-NFM. The interferents did not give significant overlapping current signal during the determination of glucose. Also, PVdF/PAPBA-NFM possesses better reproducibility toward glucose detection and storage stability.
