Nanostructured Casting of Organic and Biopolymers in Porous Silicon Templates
Researchers at UC San Diego have demonstrated the templating of solution-cast and injection molded thermoplastic organic, inorganic, and biopolymers in porous Si multilayer (Rugate, Bragg filter) structures. The castings retain the photonic structure of the template. Demonstrated uses of the castings include vapor sensors, deformable and tunable optical filters, as well as self-reporting, bioresorbable drug-delivery materials.

Title: Nanostructured casting of organic and bio-polymers in porous silicon templates
Usefulness: Nanostructured casting of organic and bio-polymers in porous silicon templates
Summary: The method is used for generating three-dimensional nanostructures, such as freestanding porous polymer film, freestanding mechanically deformable filter, biocompatible bioresorbable polymer nanostructures, and biodegradable nanostructures for controlled drug delivery system (claimed). The nanostructure includes vapor sensors, chemical sensors, biological sensors, bioimplant materials, optical switching devices, information displays (cathode ray tube, liquid crystal displays (LCDs), photonic crystals, dielectrical mirrors, microcavities and other optical structures.
Novelty: Generating three-dimensional nanostructures e.g. chemical sensors and optical filters, involves creating porous silicon template from silicon substrate, depositing material into the template, and removing the porous silicon template
