Selective dual-side functionalization of hollow SiO2 micropillar arrays for biotechnological applications
Abstract
We report a method for the fabrication and selective functionalization of the internal and external surfaces of high-aspect-ratio hollow silicon dioxide (SiO2) micropillar arrays. The strategy enables independent surface reactions with no cross-contamination. The dual-functionalization is carried out during the fabrication of the micropillars in four steps. First, a sample of macroporous silicon is prepared by electrochemical etching and then it...
