Abstract

Whispering gallery mode microtoroid optical resonators are one of the most sensitive and rapid optical sensors in existence. These sensors can detect extremely low analyte concentrations down to attomolar levels on the order of seconds. How these sensors have such a rapid response time even at these low concentrations is a question in the field. Here, we show that total analyte arrival and binding time can occur in seconds using flow visualization and finite-element simulations.
