Abstract

This chapter reveals the attractive features of the detection membrane system using nanosized Particles/fibers are its simplicity and extremely high sensitivity. In particular, the increased available surface area of nanoscale particles/fibers and the enrichment of analyte have achieved unusually high sensitivity. In order to realize an "on-site" detection system by the present nanoparticle/fiber-based chemical sensors, a compact kit may be created, that would include a water sampler, pre-filtration membrane to remove insoluble particles, and appropriate buffer and masking reagents. A syringe-type sampling system, sandwiched with the membrane-type color sensor, is a primary candidate for the simultaneous achievement of sampling, removal of interfering ions, and signalization.
