“…Nowadays many emergent applications make use of organic materials for realizing low cost devices, ranging from chemical [1], and biomedical sensors [2], to organic electronics [3], and to the development of inexpensive photovoltaic cells [4], and field-effect transistors [5]. These devices often use innovative materials including conjugated polymer and nanostructured inks, compatible with low cost deposition tools [6,7].…”

“…Because of their ubiquity and low oxidation potential, NADH‐dependent enzymes are widely applicable in biosensor, bioenergy and bioconversion technologies 2–17. For example, biosensors for alcohol 2,5–8,18, lactate 3, glucose 9, glycerol 12 and isocitrate 10 in the Kreb’s cycle have been reported. Dehydrogenase fuel cells were first reported by Palmore et al.…”

Electropolymerizing azines on a carbon nanotube (CNT) modified electrode yields a high-surface area interface with excellent electrocatalytic activity towards NADH oxidation. Electrodeposition of poly(methylene green) (PMG) and poly(toluidine blue) (PTBO) on the carboxylated CNT-modified electrodes was achieved by cyclic voltammetry. The PMG-CNT interface demonstrates 5.0 mA cm À2 current density for NADH oxidation at 50 mV vs. Ag j AgCl in 20 mM NADH solution. The kinetics of NADH electrocatalysis were analyzed using a quantitative mass-transport-corrected model with NADH bulk concentration and applied potential as independent variables. This high-rate poly(azine)-CNT interface is potentially applicable to high-performance bioconversion, bioenergy and biosensors involving NADH-dependent dehydrogenases.

The “ligand induced electroless plating (LIEP) process” is a simple process to obtain localized metal plating onto flexible polymers such as poly(ethylene terephtalate) and polyvinylidene fluoride sheets. This generic and cost‐effective process, efficient on any common polymer surface, is based on the covalent grafting by the GraftFast process of a thin chelating polymer film, such as poly(acrylic acid), which can complex copper ions. The entrapped copper ions are then chemically reduced in situ and the resulting Cu0 species act as a seed layer for the electroless copper growth which, thus, starts inside the host polymer. The present work focuses on the application of the LIEP process to the patterning of localized metallic tracks via two simple lithographic methods. The first is based on a standard photolithography process using a positive photoresist masking to prevent the covalent grafting of PAA in designated areas of the polymer substrate. In the second, the patterning is performed by direct printing of the mask with a commercial laser printer. In both cases, the mask was lifted off before the copper electroless plating step, which provides ecological benefits, since only the amount of copper necessary for the metallic patterning is used.
