We show a photolithography technique that permits gold nanowire array electrodes to be routinely fabricated at reasonable cost. Nanowire electrode arrays offer the potential for enhancements in electroanalysis such as increased signal-to-noise ratio and increased sensitivity while also allowing quantitative detection at much lower concentrations. We explore application of nanowire array electro...

Polymers of intrinsic microporosity (PIMs) provide high surface area materials (typically 1000 m2 g?1 apparent BET area) that are processable from organic solvents to give glassy films or composite coatings. Multi-functionality for sensing with these is achieved (i) based on the polymer backbone itself being fluorescent chemically active (ii) guest species (chromophores, nano-catalysts, nano-ph...

Nanodendritic Pd electrodeposited on poly(3,4-ethylenedioxythiophene) (PEDOT) modified Pd nanodendrite electrodes has been studied for electroanalysis of As(III) in 1 M HCl solution. The Pd nanodendrites are grown on a porous thin film of PEDOT by electrodeposition process. Pd-PEDOT/C electrodes are characterized by physicochemical and electrochemical studies. Cyclic voltammetry studies show th...
