Advances on ultra-sensitive electrospun nanostructured electrochemical and colorimetric sensors for diabetes mellitus detection

Abstract

Recent developments in the biochemical and medicinal industries have been heavily focused on producing affordable glucose biosensors due to the continuous annual increase of diabetic patients worldwide. The development of a fast, accurate, and reliable glucose sensor will increase confidence in controlling diabetes mellitus and its associated health complications among the diabetic community. Electrospinning is a versatile method that can produce complex nanofibrous assemblies with attractive and functional characteristics from various polymers. Electrospun nanofibers demonstrated high efficiency in the immobilization of biological molecules, which can improve the sensing performance further. Integration of polymer electrospun nanofibers with metal nanoparticles, metal oxide or transition metal in producing nanobiocomposites is also a highly popular approach in the past few years. This report presents the current progress and research trends of the technique, focusing on various materials and fabrication strategies used to produce biosensing interfaces. This helps readers decide the suitable approach in designing highly sensitive, selective, fast, and inexpensive glucose sensors.
