Photothermal Nanoparticles Extend Range of Optogenetics

Facebook Twitter LinkedIn Email Comments
Targeted gold nanoparticles allow light to activate neurons, a finding that could enable the use of optogenetic techniques without genetic manipulation. “This is effectively optogenetics without genetics,” said professor Dr. Francisco Bezanilla of the University of Chicago. “Many optogenetic experimental designs can now be applied to completely normal tissues or animals, greatly extending the scope of these research tools and possibly allowing for new therapies involving neuronal photostimulation.” Optogenetics, the use of light to control neural activity,...Read full article
