Shaped microcomponent via reactive conversion of biologically-derived microtemplates
First Claim
1. A method for the production of a shaped microcomponent, comprising:
- a) providing at least one biologically-derived silica microtemplate having an original chemical composition and an original dimensional feature, wherein the at least one biologically-derived silica microtemplate is a frustule of a diatom species; and
b) subjecting said at least one biologically-derived silica microtemplate to at least one chemical reaction so as to at least partially convert said at least one biologically-derived silica microtemplate into a shaped microcomponent comprising a solid oxide, wherein the at least one chemical reaction is selected from the group consisting of additive reaction, metathetic reaction, oxidation-reduction reaction, or combinations thereof; and
wherein at least a portion of the shaped microcomponent has a different chemical composition than the biologically-derived silica microtemplate, but substantially the same dimensional feature as the biologically-derived silica microtemplate.

Abstract
The present invention is focused on a revolutionary, low-cost (highly-scaleable) approach for the mass production of three-dimensional microcomponents: the biological reproduction of naturally-derived, biocatalytically-derived, and/or genetically-tailored three-dimensional microtemplates (e.g., frustules of diatoms, microskeletons of radiolarians, shells of mollusks) with desired dimensional features, followed by reactive conversion of such microtemplates into microcomponents with desired compositions that differ from the starting microtemplate and with dimensional features that are similar to those of the starting microtemplate. Because the shapes of such microcomponents may be tailored through genetic engineering of the shapes of the microtemplates, such microcomposites are considered to be Genetically-Engineered Materials (GEMs).
