The invention is directed to an electrode, suitable for use in a fuel cell, consisting of a microporous current collector incorporating a multitude of domains and wherein each domain contains soluble redox catalyst.

Fuel cell electrode with redox catalyst

A microsphere for use in a bioassay comprising a glass core coated with a nanoparticle composite comprising a bioactive probe is provided. The nanoparticle composite coating enhances the density of bioprobe loading on the surface of the microspheres, resulting in enhanced dynamic range and sensitivity in bioassays. The particle may be used in detection systems where resonant light scattering properties of the particle are useful.
