Copper, an old material, is still extensively used nowadays. In this paper, through extremely simple replacement reaction approach, we synthesized various copper nanostructures under ambient atmosphere at room temperature. Pure copper, with splendid structures at nanoscale, was acquired by dipping iron plate into solution with copper ions. With different reactant, copper chloride, copper sulfate,...
Global efforts have been made in the past two decades to efficiently manipulate and assemble tiny entities at micro-scale or even nano-scale. In this paper, we discuss our team's development of adding an interactive controller to the emerging optically-induced dielectrophoresis (ODEP) platform which could be used to rapidly and parallelly manipulate micro and nano particles in fluidic medium. We have...
This study reports an approach to dynamically separate cultured human B-lymphoma (Raji) cells from normal human red blood cells (RBCs), mixed in an isotonic solution, by utilizing a hydrogenated amorphous silicon-based optically-induced electrokinetics chip. A theoretical calculation of the polarization model for the two different types of cells is first presented. The differential velocity between...
