Scientists use lasers to control genes.
Scientists have figured out how to control genes in cancer cells using nanotechnology and lasers.
Researchers at the University of California at Santa Barbara were able to use microscopic gold nanoshells to introduce a drug called silencing ribonucleic acid into mouse cells. The cells were then zapped with a non-harmful laser to activate the drug. This technique could allow doctors to turn genes including genes that cause cancer on and off when it is perfected, according to Norbert Reich, a professor at UCSB.
So far scientists have only tested this technology on cells grown in a dish and not on cells in a fully grown mouse. The results of the research were published in ACS NANO, a journal of the American Chemical Society.
