Nanoparticle thin film-based sensors offer several advantages over traditional sensor types, especially in electrochemical sensing. The main challenge has been the fabrication of the nanoparticle sensing layer. Two main methods have been used; layer-by-layer (LbL) and Langmuir-Blodgett (LB).
Nanoparticle lithography is a promising fabrication technique. Unlike other techniques, it has a potential to be performed on curved surfaces.
Nanoparticles and thin films made from nanoparticles are gaining recognition and use in various products and applications including displays, sensors and energy storage.
