DOI: 10.1016/j.molliq.2018.07.005
Abstract: Abstract The present work deals with experimental determination of steady state fluorescence anisotropies, fluorescence lifetimes and consequentially the rotational reorientation times of three large, nonpolar laser dyes that are modelled as prolate ellipsoids. Steady state… read more here.

DOI: 10.1088/1367-2630/abdb70
Abstract: Biological cells estimate concentration gradients of signaling molecules with a precision that is limited not only by sensing noise, but additionally by the cell’s own stochastic motion. We ask for the theoretical limits of gradient… read more here.

DOI: 10.3390/membranes12100962
Abstract: The spin-lattice relaxation rate (T1−1) of lipid spin labels obtained from saturation recovery EPR measurements in deoxygenated membranes depends primarily on the rate of the rotational diffusion of the nitroxide moiety within the lipid bilayer.… read more here.
