Nanomaterials generating or enhancing glucose measuring signals


Nano-materials, by virtue of their nanoscale dimensions, make it possible to extend glucose sensing technologies beyond the limitations of conventional electrodes. In other words, the advent of nanotechnology opened up huge scope for development of miniature and CGM systems having wider detection limits and better sensitivity. Typically, nanomaterials have high surface area to volume ratios and high surface activity, due to which and depending on the ambient environment, often the same material behaves as electrical or thermal conductor, semi-conductor, optical or mechanical transducer. Hence, their unique catalytic and signal transducing abilities find them a variety of sensing applications.
