The purpose of the present invention is to describe a novel approach for converting 3-dimensional, synthetic micro- and nano-templates into different materials with a retention of shape/dimensions and morphological features. The ultimate objective of this approach is to mass-produce micro- and nano-templates of tailored shapes through the use of synthetic or man-made micropreforms, and then chemical conversion of such templates by controlled chemical reactions into near net-shaped, micro- and nano-components of desired compositions. The basic idea of this invention is to obtain a synthetic microtemplate with a desired shape and with desired surface features, and then to convert the microtemplate into a different material through the use of chemical reactions.
