Despite the variability of the pore size, the three materials tested here all showed an ability to detect and count nano/micro-materials. A universal mounting system to integrate these into the fluidic chip was then designed. The first iteration of this design is shown in figure . The membrane material was sandwiched between two O-rings and held in place within the fluidic chip via the standard screw thread. A Ag/AgCl reference electrode was positioned behind the membrane.
