Speaker Jaeda Mendoza, FCRH ’22, engineering physics major, will present “Towards a Plasmon Coupled Micro-Cavity Biosensor.”

Plasmonics enables the enhancement of resonance shifts in cavity-based sensors in the presence of a foreign substrate, altering the refractive index of surrounding dielectrics. This method of sensing can be used for general sensing, most especially for the trace detection of biological and chemical agents. However, some sensors use fragile materials or are difficult to manage, often causing problems. Thus, there is a need to find alternative sensor platforms that can mitigate such problems. This research project aims to determine whether perforated gold plates as a plasmonic sensor platform will be a better alternative sensor when coupled with a microsphere resonator.

This event is open to faculty/staff, students, and the public.
