This paper presents the fabrication of the inter-porosity carbon nanofibers (CNFs) obtained by the Carbon Microelectromechanical Systems (C-MEMS) method using electrospinning of SU-8 2100 photoresist polymer, photolithography, and pyrolysis techniques. The optimized electrospinning parameters identified in this research produced smooth inter-porosity CNFs with an average fibre diameter range between 167 ± 58 nm and 197 ± 104 nm. The CNFs samples were subsequently investigated using the cyclic voltammetry (CV) technique at sweep rate 50 mV s−1 with Zobell’s solution as a redox probe in three-electrode configuration CNFs as working electrode (WE), counter electrode (CE), and reference electrode (RE) from the screen-printed electrode (SPE). Based on CV analysis, the inter-porosity CNFs showed that the CV curve obtained at high sweep rates proved that the consumption of redox species rate at the electrode surface is very high. Additionally, the high surface area of our developed CNFs has the potential to be used as massive regions for bacteria detection with further modification of electrode configuration; leading to an increase in the detection sensitivity. © 2022, Springer Nature Switzerland AG.
