Integrating CMOS technology with nano-materials can lead to novel, super-sensitive imagers
Aluminum and dielectric nanowires can be designed to have spectral and polarization filtering properties
Integration of nano-materials with CMOS technology allows for compact and wearable imagers
Custom signal processing algorithms allow for enhanced imaging of cancerous tissue
Major challenge has been bringing this technology to the operating room
The technology is currently in clinical trials
This technology is helping surgeons ensure that all cancerous cells are removed from a patient
