💎 Photonic-Crystal Nanocavity Biosensor

Tune the Q-factor of a dielectric photonic-crystal nanocavity and watch single biomolecules bind one at a time in its evanescent-field hotspot, shifting a live transmission-spectrum resonance peak — see why a high Q-factor is what makes a single binding event detectable.

⚙ Under the hood

Tune the Q-factor of a dielectric photonic-crystal nanocavity and watch single biomolecules bind one at a time in its evanescent-field hotspot. A live transmission-spectrum chart shows the sharp resonance peak shift with each binding event — at low Q the shift is buried in a broad linewidth, at high Q the very same single-molecule shift is clearly resolvable.
