Ultrasensitive metasurface sensor based on quasi-bound states in the continuum

open access: yesNanophotonics
The quasi-bound state in the continuum (quasi-BIC) of dielectric metasurface provides a crucial platform for sensing, because its almost infinite Q-factor can greatly enhance the interactions between light waves and the analytes.
