Item Stain free colorimetric sensors using hybrid mode plasmonic microscopy(IEEE, 2016) Arora, PankajWe present colorimetric stain free image based sensing of antibody-antigen binding and refractive index perturbation, using substrates that support hybrid mode surface plasmons and demonstrate their integration with microfluidic channels for real time index sensing.Item Dispersion engineering with plasmonic nanostructures for enhanced surface plasmon resonance sensing(IEEE, 2018) Arora, PankajWe experimentally demonstrate plasmonic resonance narrowing via dispersion engineering using plasmonic nanogratings placed on top of thin metal coated prism. The enhancement in Q factor, combined with strong field localization is attractive for sensing applications.
