Research

My research focuses on the numerical and experimental exploration of nanostructured plasmonic sensors, with a comprehensive approach encompassing design, fabrication, characterization, and application-level integration. Currently, I am working on the fabrication of solid and porous gold nanodisc arrays on glass substrates, employing techniques such as Langmuir-Blodgett trough-based nanosphere lithography (NSL), electron beam lithography (EBL), and various soft nanoimprint lithography to achieve tunable optical properties. These nanostructures are utilized in localized surface plasmon resonance (LSPR)-based sensing platforms for detecting proteins, extracellular vesicles, and cancer exosomes using bright-field and dark-field imaging techniques.

In addition to my work on nanodisc fabrication, I have experience in the chemical synthesis of metal nanoparticles and the preparation of metal nanoparticles through thermal dewetting techniques. I am also skilled in soft photo/thermal lithography techniques and low-energy ion beam irradiation of metallic nanostructures. Moreover, I have expertise in surface-enhanced Raman scattering (SERS) measurements.
