In literature, the application of sensors based on electrospun
fibers mainly focus on an improvement of sensitivity and accuracy,
with minor focus on sensor response dynamics [18–21]. In this
paper we report the significant acceleration of the sensor response
by electrospinning of a typical opto-chemical oxygen sensor formulation,
consisting ofplatinum-tetra(pentafluorophenyl)porphyrine
(PtTFPP) which is immobilized in a polystyrene (PS) matrix (oxygen
detection range 0–100% oxygen) to form a highly porous 3D
non-woven nanofiber membrane.
