Nanoplasmonic biosenA nanoplasmonic substrate consisting of mushroom-like structures immobilized with antibodies. The substrate is exposed to white light which drives localized plasmon resonances in the nanomushrooms. These resonances are sensitive to changes in local refractive index due to binding of molecules, enabling enhanced label-free sensing. Credit: Shivani Sathish & Nikhil Bhallasors
These nanoplasmonic materials with mushroom-shaped nanostructures allow for real-time monitoring of cellular growth and potential disease detection.
