You must be aware of the Quantun dots that helps to trace out the disease molecule inside cells or body. According to National Cancer Institute’s Alliance for Nanotechnology, Stanford investigators have introduced self-illuminating bright quantum dots, thereby no need for external light source to be visualized.



A team under Jianghong Rao, Ph.D., a member of the Stanford CCNE (Center for Cancer Nanotechnology Excellence) developed a method for protein coating over the quantum dots. A molecule called coelenterazine is attached to the quantum dots that produce the bright fluorescent light.



The researchers claim that this technology could be utilized to add variant proteins and to chemically label cells also.
