We demonstrate an optomechanical accelerometer using a v-groove fiber coupled photonic-crystal nanocavity integrated with a high-Q nanotethered test mass. The nanocavity frequency can be tuned to that of an input laser by on-chip capacitive actuators.
Abstract: Ricin is a potential bioterrisiom agent. There is a critical need for a method that can rapidly and simply detect ricin and other bioterrisiom agents in complex food matrices such as milk. In this study, we demonstrated a rapid method that combined immunomagnetic separation (IMS) and surface‐enhanced Raman spectroscopy (SERS) to detect ricin in whole milk. IMS was used to specifically capture...
