Abstract

Films of polyallylamine hydrochloride (PAA) and polysteresulfonate sodium salt (PSS) were formulated using the polyelectrolyte self-assembly technique. Electrical measurements show that there is no presence of counter ions and films are electrically stable. Responses of composite films of PAA/(indicator/PAA)_n(Enzyme/PAA)_m deposited on suitably treated glass substrates to heavy metals and pesticides are found to be selective from their optical absorption spectra
