The present invention provides a method for increasing the sensitivity of LFIAs by using palladium nanoparticles, selecting appropriate dye chemistries, and improving the timing of the development chemistry. In the presence of a palladium nanoparticle, three reagents interact with a catalytic label to form a colored dye. The three reagents include a hydrogen peroxide source, a color developer (a substituted para-phenylenediamine), and a color coupler (e.g. a napthol or a phenol). The timing of the development chemistry is improved by any combination of using a reducing agent, delaying hydrogen peroxide application by diffusion, using dissolving materials as a time delay, using serpentine flow, and separating the color coupler and the color developer on the strip.

A method and device incorporating the use of Zinc Oxide to generate electrical power directly from heat, with minimal or no complex and inefficient mechanical interventions, by making advantageous use of the abundance and low cost of ZnO and its pyroelectric and thermoelectric properties. ZnO is used as a cheap, under-used material for the purpose of converting thermal energy (heat) directly into usable electricity with none or almost none of the mechanical conversion systems generally in use.
