Motivated by the growing efforts for miniaturization, on chip nanoscale photonic and plasmonic based devices and systems are becoming a reality. In this talk I de- scribe our recent progress towards the construction of on chip passive and active devices based on silicon photonics and silicon plasmonics technologies. This effort includes the demonstration of plasmonic enhanced silicon photo detectors for the infrared, nanostructures for enhanced light vapor interactions, advanced chip scale memories and ultra-high precision measurements with nanophotonics.

Magneto-nanosensors based on magnetic nanoparticle (MNP) labeling of biomolecules (such as proteins and DNA) and giant-magnetoresistive sensors used in computer hard drives have gained great interests in nanotechnology and biomedicine community. Here we will elucidate their intricate operation principles and explain the details of several killer applications of these emerging devices in precision medicine and precision health.
