Journal ArticleDOI
On-chip single nanoparticle detection and sizing by mode splitting in an ultrahigh- Q microresonator
Jiangang Zhu,Sahin Kaya Ozdemir,Yun-Feng Xiao,Yun-Feng Xiao,Lin Li,Lina He,Da-Ren Chen,Lan Yang +7 more
TL;DR: In this article, the authors report real-time detection and sizing of single nanoparticles, down to 30 nm in radius, using mode splitting in a monolithic ultrahigh-quality-factor (Q) whispering-gallery-mode microresonator.
Journal ArticleDOI
Single virus and nanoparticle size spectrometry by whispering-gallery-mode microcavities.
TL;DR: It is shown that the size of each particle and virion can be measured as they continuously bind to the resonator one-by-one, eliminating the need for ensemble measurements, stochastic analysis or imaging techniques employed in previous works.
Journal ArticleDOI
Erratum: On-chip single nanoparticle detection and sizing by mode splitting in an ultrahigh-Q microresonator (Nature Photonics (2010) 4 (46-49))

Nanoscale Object Detection Using A Whispering Gallery Mode Resonator
TL;DR: In this article, the presence of an object is determined based on mode splitting associated with the light received by the photodetector using a light source and a whispering gallery mode (WGM) resonator.
Proceedings ArticleDOI
Detection and sizing of single nanoparticles by mode splitting in an optical microresonator
TL;DR: In this article, the authors demonstrate detection and sizing of single nanoparticles down to 30 nm by monitoring the mode splitting induced by a nanoparticle in an ultra-high quality factor (UHQ) microtoroid.
