The structure of porous silicon is of interest for cell biological applications due to the large surface area and optical properties. To render the material biocompatible we modify porous silicon using hydrosilylation and bioconjugation techniques to render it inert to degradation and allow for cell adhesion. We looked at the potential to use porous silicon as a co-culture by patterning it with patterned regions of different adhesive peptides using a novel lithography method with gold. Next we exploited the high surface area of the material to incorporate small molecules in the structure. Then we used it for cell culture, so that drug releases directly into the cells. We then explored the optical properties of porous silicon to create a stimuli responsive sensor using a composite with a PEG hydrogel. Finally we looked at the potential of topographically modified porous silicon to be used for cell culture Item withdrawn by Mark Zulauf (zulauf@illinois.edu) on 2014-07-16T21:30:21Z Item was in collections: University of Illinois Theses & Dissertations (ID: 1) No. of bitstreams: 2 Huang_tiffany.docx: 31034068 bytes, checksum: e4b966e184980852e466068d4dde85b8 (MD5) Huang_Tiffany.pdf: 3494089 bytes, checksum: cfeaff37acfea7cb95a16c11b13af0f9 (MD5) Made available in DSpace on 2014-09-16T17:17:46Z (GMT).
