Journal ArticleDOI
Shift of whispering-gallery modes in microspheres by protein adsorption
TL;DR: The theoretical shift for adsorption of a single protein is found to be extremely sensitive to the target region, with adsor adaptation in the most sensitive region varying as 1/R(5/2).
Journal ArticleDOI
Label-free detection of single protein using a nanoplasmonic-photonic hybrid microcavity.
Venkata Ramanaiah Dantham,Stephen Holler,Stephen Holler,Curtis Barbre,D. Keng,Vasily Kolchenko,Stephen Arnold +6 more
TL;DR: The detection of single thyroid cancer marker (Thyroglobulin, Tg) and bovine serum albumin (BSA) proteins with masses of only 1 ag and 0.11 ag are reported with surprising sensitivity to single protein.
Journal ArticleDOI
Whispering Gallery Mode Carousel--a photonic mechanism for enhanced nanoparticle detection in biosensing.
TL;DR: This Carousel trap, caused by attractive optical gradient forces, interfacial interactions, and the circulating momentum flux, considerably enhances the rate of transport to the sensing region, thereby overcoming limitations posed by diffusion on such small area detectors.
Journal ArticleDOI
Real-time measurement of fluorescence spectra from single airborne biological particles
Steven C. Hill,Ronald G. Pinnick,Stanley Niles,Yong-Le Pan,Stephen Holler,Richard K. Chang,Jerold R. Bottiger,Bean T. Chen,Chun-Sing Orr,Greg A. Feather +9 more
TL;DR: In this paper, the authors present a real-time system for measuring the laser-induced fluorescence (total and spectrally dispersed) of individual airborne particles, which can distinguish between some biological and nonbiological aerosols, and among several types of laboratory-generated biological aerosols.
Journal ArticleDOI
Plasmonic enhancement of a whispering-gallery-mode biosensor for single nanoparticle detection
TL;DR: In this paper, the authors describe and demonstrate a physical mechanism that substantially enhances the label-free sensitivity of a whispering gallery mode biosensor for the detection of individual nanoparticles in aqueous solution.
