Effect of Gold/Amine Nanoparticles on Polyaniline Electrochemical Sensitivity to Formaldehyde.

Background: Nanoparticles have a promising potential in electrochemical sensitivity. Polyaniline (PANI) received significant attention in the latest years owing to its high conductivity and excellent electrochemical stability. This research aims to study the effect of gold nanoparticles capped octadecyl amine (Au/ODA) on polyaniline emeraldine salt (ES) electrochemical sensitivity to formaldehyde (FA) using DPV technique.

Preparation and Characterization of Novel Polyaniline Nanosensor for Sensitive Detection of Formaldehyde.

Nanomaterials are promising in the field of optical sensors due to their unique properties. Emeraldine base of polyaniline (Nano EB-PANI) was prepared, characterized and applied as an optical formaldehyde sensor. FTIR data confirm the formation of the EB-PANI.
