Biomedical applications of nanostructured column-void Si

摘要

We report on various biomedical applications of our nanostructured column-void Si films including respiratory monitoring, quick mass analysis for proteomics, and cell attachment. These applications exploit certain unique attributes of our nanostructured Si material that do not exist in bulk Si, such as molecular immobilization, enhanced coupling with electromagnetic radiation, high surface area, and pronounced hydrophobiciry at its as-deposited state. A brief review of morphology and film growth is also given according to our latest understanding.
