In this work, we demonstrate an optical fibre tip sensor coated with chitosan for lead ion (Pb2+) detection. The sensor was fabricated using a tip of standard single mode optical fibre. The fibre tip region was cleaved and dipped into chitosan solution to form a sensitive layer. The coated sensor wa...
