Orbital Dynamics at Atmospheric Pressure in a Lensed, Dual-beam, Optical Trap
Amala Raj, William L. Schaich, Bogdan Dragnea
Orbital optical trapping of a dielectric micro-particle in air was studied experimentally using a lensed, counter-propagating dual-beam trap, and by numerical simulations employing…

Radiation Brightening from Virus-like Particles
Irina B. Tsvetkova, Arathi Anil Sushma, Joseph C. -Y. Wang +2
Concentration quenching is a well-known challenge in many fluorescence imaging applications. Here we show that the optical emission from hundreds of chromophores confined onto the…
