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…
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…
Virus Assembly Pathways inside a Host Cell
Sanaz Panahandeh, Siyu Li, Bogdan Dragnea +1
Simple RNA viruses self-assemble spontaneously and encapsulate their genome into a shell called the capsid. This process is mainly driven by the attractive electrostatic interactio…
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…
A three-dimensional discrete model for approximating the deformation of a viral capsid subjected to lying over a flat surface
Paolo Piersanti, Kristen White, Bogdan Dragnea +1
In this paper we present a three-dimensional discrete model governing the deformation of a viral capsid, modelled as a regular icosahedron and subjected not to cross a given flat r…
Modelling Virus Contact Mechanics under Atomic Force Imaging Conditions
Paolo Piersanti, Kristen White, Bogdan Dragnea +1
In this paper we present a discrete model governing the deformation of a convex regular polygon subjected not to cross a given flat rigid surface, on which it initially lies in cor…
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…
Contact Mechanics of a Small Icosahedral Virus
Cheng Zeng, Mercedes Hernando-Pérez, Xiang Ma +3
Virus binding to a surface results at least locally, at the contact area, in stress and potential structural perturbation of the virus cage. Here we address the question of the rol…
