A great number of polymers can be electrospun to nanofibers,
and the electrospinning process generally is not impeded by the
addition of luminescent dyes [10,17]. Typical polymer–dye formulations
used for compact layers in conventional opto-chemical
sensor systems may therefore be replaced by electrospun polymer
nanofiber membranes with only a few optimization steps. The
application of such membranes may result in greatly enhanced
response characteristics due to the extraordinary surface-tovolume
ratio and good analyte accessibility
