Results

 

•Made robust, mechanically deformable rugate filters using porous Si templates.


•Improved chemical stability by in situ polymerization and cross linking of pores using ring-opening metathesis catalyst.


•Demonstrated optically encoded “smart dust” for antibody detection in high throughput screening application.
