– We propose a model for the dynamics of a probe embedded in a living cell, where both thermal fluctuations and nonequilibrium activity coexist. The model is based on a confining harmonic potential describing the elastic cytoskeletal matrix, which undergoes random active hops as a result of the nonequilibrium rearrangements within the cell. We describe the(More)
In this work, a novel polymeric fluorescent brightener agent based on 4,4′-diamino-stilbene-2,2′-disulfonic acid-triazine structure has been synthesized by radical polymerization. The structure of 4,4′-diamino-stilbene-2,2′-disulfonic acid -based polymeric fluorescent brightener agent was characterized by Fourier-transform-infrared spectroscopy, 1HNMR, and(More)
Aminoacyl-tRNA synthetases (aaRS) have been essential enzymes for protein synthesis throughout evolution. As the tree of life was ascended, tRNA synthetases added new domains, which are generally dispensable for aminoacylation, in a progressive and accretive manner. The acquisitions were timed to specific points in evolution, such as the transition from(More)
—Micrometer and sub-micrometer sized non-magnetic particles were manipulated by an external strong magnetic field (e.g., 10 Tesla) with a high gradient. During the strong magnetic field effects, segregation of the non-magnetic particles was observed which could not be realised only with gravitational field. Numerical calculations were subsequently carried(More)
