An efficient method is therefore highly desirable（but challenging） for analytical/preparative purification of DNA-conjugated nano-objects and their DNA-assemblies. In this regard, agarose gel electrophoresis, a traditional technique that has been invented for biomacromolecule separation, has found many innovative uses.This includes shape, size, charge, and ligand-valence separations of nanoparticle building blocks as well as monitoring a self-assembly process towards product identification and purification.展开更多

DA controls complex and specialized functions including, movements, behavior, mood, perception, reward, and more recently, neurogenesis （Popolo et al., 2004; Reimer et al., 2013） and neuroregeneration （Hoglinger et al., 2004; Yang et al., 2008）. These functions are varied and of high fidelity. Movement, as an example, requires regulatory mechanisms for initiating, stopping, slowing-down speed- ing-up, changing directions, for governing the relentless urges to move in the young and sedentariness in the old as well as in motor-freezing, catalepsy, tremor and stereotypy.展开更多
