The section below presents a brief review of the existent nanofiber biosensor configurations. Starting from the glucose sensor which was the earliest sensor developed in the history of biosensing, each realm is being replaced with nanofibers for improving sensor properties. An outline of the modifications made by incorporation... 

Polymer nanofiber-based biosensors have been developed, based on the above-mentioned principle of the glucose sensor. Nylon-6 nanofibers have been electro-spun, impregnated with Au nanoclusters (for increasing conductivity) and immobilized with glucose oxidase. The schematic diagram of the sensor is shown in Figure 15.4. 

Figure 7. (a) Cyclic voltammetric (CV) spectra for the GOX-immobilized HCSA-PANI/PS nanofiber sensors at different glucose concentrations, and (b) The current response of the GOX-immobilized HCSA-PANI/PS nanofiber andfilm sensors to various glucose concentrations. Note the current response has been scaled by the weight of the polymeric material deposited on the electrodes (35). 

Figure 15.6. Shows the plot of (A) glucose concentration versus potential and (B) conversion chart of glucose concentration versus voltage for the nanofiber-based sensor.
