1. Optical Techniques for Cancer Margin Assessment

Cancer margin assessment is key to improve the success rate of Breast Conservation Surgery (BCS). Different optical techniques such as transmission-based NIR, diffuse reflectance-based NIR, time-domain NIR, linear and circular polarization-based polarimetric tools can be used with varying efficacy to differentiate cancer from adjacent normal tissues.

2. Multispectral Intraoral Cancer Probe for Low-Resource Settings

Currently, the visual inspection by the clinician in the primary health center is inadequate for accurately diagnosis type and stage of oral cancer. Using multispectral imaging, that selectively exciting the intraoral cavity with different wavelengths based on the absorption peaks of HbO2 and Hb can help in characterizing the tissue. A portable and affordable intraoral cavity probe can be used in the primary health center which can potentially aid the clinician to improve the efficacy of oral cancer diagnosis.

3. Bio-inspired Optical Materials and Devices

With the advent of high-resolution imaging tools, the finest intricacies of the microscopic environment of biological entities such as moth-eye, camouflage, and bird's feather can be understood. These microstructures can generate macroscopic behaviour such as optical filters and reflectors, leading to applications such as implantable sensors, diagnostics, and therapeutics.
