Optofluidic SERS Sensing from Photonic Crystal-Plasmonic Mesocapsules

Not Accessible

Your library or personal account may give you access


We synthesized hybrid photonic crystal-plasmonic mesocapsules using diatom biosilica with in-situ growth silver nanoparticles. The mesocapsules achieved near single-molecule sensitivity for optofluidic SERS sensing with five orders of magnitude higher than colloidal nanoparticles.
