Main scientific/ clinical interest: We focus on smart nanofabrication techniques that provides fast and large area manufacturing of metamaterials that works as optical biosensors. We use the designed sensors for sensing of very low number of (femtomolar level) target molecules (e.g. relevant to brain metastasis) in the visible frequencies. We also use these sensors for the surface enhanced infrared absorption spectroscopy to detect and identify the organics. We combine the sensors with valve integrated microfluidic devices for automated cell and tissue handling that enables real time interrogation.

Techniques/ approaches you will contribute to RISEbrain: Micro/Nanofabrication, Metamaterials as biosensors, spectroscopy in the visible and IR frequencies, microfluidic handling of samples.
