- Whispering Gallery Mode Carousel--a photonic mechanism for enhanced nanoparticle detection in biosensingS Arnold
MicroParticle PhotoPhysics Lab, Polytechnic Institute of NYU, Brooklyn, New York 11201, USA
Opt Express 17:6230-8. 2009..Since the attractive forces draw particles to the highest evanescent intensity at the surface, binding steps are found to be uniform...
- Ultrasensitive nanoparticle detection using a portable whispering gallery mode biosensor driven by a periodically poled lithium-niobate frequency doubled distributed feedback laserS I Shopova
MicroParticle PhotoPhysics Laboratory for BioPhotonics, Polytechnic Institute of New York University, Brooklyn, New York 11201, USA
Rev Sci Instrum 81:103110. 2010..The noise equivalent detection limit is ∼20 ag (17 nm radius). This new lower limit is attributed to the ultralow resonance wavelength noise [(Δλ(r))(rms)/λ(r)<10(-9)] associated with the use of the DFB-PPLN device...
