The experienced professionals at the Nanoengineering Core at Houston Methodist develop and produce state-of-the-art silicon-based bio-nanotechnology using micro-fabrication techniques, achieving some of the highest levels of scalability, precision and reproducibility necessary for accurate clinical applications. Using industry-proven silicon fabrication techniques, coupled with chemical methods, we create novel nanomaterials and nanodevices for biomedical applications. We have also designed fabrication protocols to make many types of porous silicon particles (PSPs) for multistage delivery systems. Owing to their biodegradability and readily modified surface properties, PSPs are emerging as promising injectable drug delivery carriers.
