1. Optical coherence tomography picorheology of biopolymer solutions

    Ramesh C. Sharma, Aristeidis Papagiannopoulos, and Thomas A. Waigh We describe an interferometric optical fiber based dynamic light scattering technique to study the linear viscoelasticity of complex fluids. This digital correlator based method enables viscoelasticity to be probed at high frequencies (1010 Hz) over picoliter regions of an aqueous sample. We demons ... [Appl. Phys.
