Abstract
A versatile methodology for designing multi-functional metal nanoparticles (NP) by first fabricating bi-material nanopyramids and differentially modifying their surfaces with chemical/biological molecules. This chemical fabrication approach can readily be expanded to generate a diverse suite of sophisticated multi-functional NPs whose properties can be exploited for a wide range of applications in biomedicine, from optical and magnetic imaging to sensitive diagnostics. Nanopyramids in particular could be important in targeted delivery and localized therapeutics because of their unconventional shape, which facilitates asymmetric functionalization and electromagnetic field enhancements at their sharp edges and tips.
