Witryna12 kwi 2024 · Let us see the separation of the time constant in the enzymatic reactions. An enzymatic reaction consists essentially of two chemical processes as clarified by Michaelis and Menten: binding or unbinding of a substrate at a cavity of protein (enzyme) and a chemical reaction or recombination of atoms in substrate molecules inside the … Witryna12 mar 2013 · The nonuniform motion of charged species in a varying electric field may provide unique separation and focusing power for chemical, biochemical, and nanoscale studies. We imaged in real time the nonuniform motion of single DNA molecules under varying-field isotachophoresis (ITP) conditions. From the trajectories of single …
Witryna29 maj 2007 · The challenges of single-molecule imaging are threefold: (i) obtaining sufficient selectivity to distinguish a single molecule from the cellular background; (ii) tracking the movement of many of these resolved single molecules over time to provide statistically significant data; and (iii) clearly distinguishing between directed motion … WitrynaCurrently, organic phosphorescent particles are heavily used in sensing and imaging. Up to now, most of these particles contain poisonous and/or expensive metal complexes. ... The latter is observed when oxygen is not in the proximity of the emitting dye molecules. These particles can scavenge singlet oxygen, which is produced during …
