Resumo

Herein, a green and low-cost approach is proposed for the production of fluorescent fibers from the electrospinning of poly (vinyl alcohol) and graphene quantum dots (citric acid based) for biosensing purposes. This hybrid material was applied as a substrate for enzyme immobilization aiming at glucose sensing. This sensor showed a high effectivity for glucose detection in the range of 1 mM to 10 mM, with a corresponding detection limit of 12 µM. These results widen the perspectives of application of this material in the sensing field, via a simple strategy using a water-soluble polymer and a naturally occurring component from citrus fruits.
