Injectable nanoparticles that enhance vision in mice

12-Dec-2020

Key points from article :

Nanoparticles attached to photoreceptors allow mice to see infrared & near-infrared light for 2 months.

Mammals can only see light in visible spectrum - not infrared and near-infrared.

“We developed up-conversion nanoparticles, that can effectively be activated by this near-infrared light.” - Gang Han, author.

Tested their system in mice - nanoparticles attached themselves to photoreceptors in mice retina.

It absorbed infrared radiation & converted into green light which the brain interprets as visible light.

Enhanced super-vision allowed animals to see & discriminate between different infrared patterns.

Did not interfere or supersede animal’s standard-issue visual abilities.

Nanoparticles remained active for as long as two months.

Method offers options for mammalian vision repair and enhancement

Research by University of Massachusetts Medical School published in Cell.

Might help the army with night vision & even treat people with colour blindness
