Abstract:

Embodiments of a method for making metal oxides or mixed metal oxides are disclosed. One representative embodiment comprises selecting a substrate for making the metal oxide or mixed metal oxide, contacting a biological system with the substrate material for an effective period of time, and optionally isolating the metal oxide or mixed metal oxide from the biological system. The biological system can be a living organism, or proteins derived from the living organism. Working embodiments used microalgae, specifically diatoms of the class Bacillariophycae, including marine Pennate diatoms, such as and/or diatoms, and Centric diatoms, such as species. The method also can involve post processing a primary or secondary material produced biologically. The metal oxides can be used for a variety of applications, including optoelectronic devices, such as memory devices, data storage devices, detectors, sensors, lasers, emitters, light-emitting diodes, optical computing architectures, photonics, imaging, photovoltaics, and administering therapeutic.

Abstract:

A composition comprising a diatom frustule and a metal coating, and a method for making the same, are disclosed herein. The metal coating may comprise a metal film or metal nanoparticles, which may be attached to the surface via a linker. The composition has a surface coverage ratio of from about 1% to about 100%. The composition may also comprise an antibody. Also disclosed is a method for using the composition comprising contacting the composition with a target molecule, exposing the composition to light, and measuring the resulting Raman scattering.
