DOI: 10.1002/cbic.202300069

Abstract: The hydrodynamic effects of macromolecular crowding inside cells are often studied in vitro by using polymers as crowding agents. Confinement of polymers inside cell‐sized droplets has been shown to affect the diffusion of small molecules. Here… read more here.

DOI: 10.1016/j.optcom.2020.126701

Abstract: Abstract Various approaches for generating phase-conjugate signal have been recently proposed that exploit the advantage of noise suppression in digital holographic microscopy (DHM). This study presents a reproducible method for generating a time-independent quasi-phase conjugated… read more here.
