Description

Selenium was a component in the Dulbecco′s Modified Eagle Medium, used for the cell culture of alpha mouse liver (AML)-12 hepatocyte cell line.Se was also employed in a water based synthesis of glutathione-capped cadmium selenide quantum dots (GSH-CdSe QDs). 3Se is used in the synthesis of CdSe, which is consequetively used to modulate the photoresponse of quantum dot solar cells by varying the size and shape of semiconductor nanostructures.
