A new nanophotonic sensing strategy converts even subtle refractive-index changes into large intensity variations via radiative Q-factor modulation. Implemented in a bound-state-in-the-continuum (BIC) metasurface, the concept enables ultrasensitive and scalable biosensing of only a few tens of tumour extracellular vesicles within 15 minutes.
