How Superradiance Survives Molecular Noise inside Virus Capsids
Tianran Li, Irina Tsvetkova, Matthew Brauser +3
Excited organic dyes chemically bound to an icosahedral virus shell can spontaneously synchronize and emit a superradiant burst of light. The mechanism that allows it to occur at r…
An Assembly-Line Mechanism for In-Vitro Encapsulation of Fragmented Cargo in Virus-Like Particles
Ayesha Amjad, Irina Tsvetkova, Lena G. Lowry +4
The ability of virus shells to encapsulate a wide range of functional cargoes, especially multiple cargoes - siRNAs, enzymes, and chromophores - has made them an essential tool in…
Ultrafast Collective Excited State Dynamics of a Virus-supported Fluorophore Antenna
Joseph Holmes, Arathi Anil Sushma, Irina B. Tsvetkova +3
Radiation brightening was recently observed in a multi-fluorophore-conjugated brome mosaic virus (BMV) particle, at room temperature under pulsed excitation. Based on its nonlinear…
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…
