A stochastic theoretical approach to study the size-dependent catalytic activity of a metal nanoparticle at the single molecule level

Sing, Divya; CHAUDHURY, SRABANTI (Royal Society of Chemistry, 2017-03)

The catalytic activity of metal nanoparticles is intrinsically heterogeneous due to the heterogeneous distribution of surface catalytic sites and surface restructuring dynamics. Recent advances in single-molecule fluorescence ...
Statistical properties of fluctuating enzymes with dynamic cooperativity using a first passage time distribution formalism

Sing, Divya; CHAUDHURY, SRABANTI (AIP Publishing, 2017-07)

We study the temporal fluctuations in catalytic rates for single enzyme reactions undergoing slow transitions between two active states. We use a first passage time distribution formalism to obtain the closed-form analytical ...
