Layer-by-layer (LbL) coating system developed capable to monitor the LbL coating process on optical fiber for sensor application in real-time basis. The objective was to determine the optimum number of bilayer coatings for best sensing performance. Multiple layers of poly(allylamine hydrochloride) (...
