light activation News
Light-Activated Tool Controls Protein Bonds and Tracks Cell Adhesion
TAMPERE, Finland, Nov. 20, 2023 — Optical tools can be used to activate biological functions, but with current methods the effects are slow to appear, and sustained effects require continuous light activation. As a result, these light-activation tools provide limited control of fast biological processes and can lead to toxicity in cells and organisms. Although light is a well-established tool for control of bond breakage, it is less firmly established for the control of specific bond formation in complex
Light-Activated Nanomachines Combat Bacterial Infections
HOUSTON, June 20, 2022 — Rice University researchers have developed visible-light-activated molecular machines that kill antibiotic-resistant bacteria in minutes by targeting the bacteria’s membranes. This approach to treating drug-resistant infections, which uses...
Nanosize Device Noninvasively Assesses Cell's Electric Field
LOS ANGELES, Jan. 13, 2022 — A nano-size, organic molecular device that can detect and manipulate its surrounding bioelectric field opens possibilities in biophotonics, specifically in wound healing and in the fight against diseases. The triangle-shaped device is made of two...
Optochemogenetics Tested for Neuronal Repair after Stroke
ATLANTA, July 3, 2019 — Researchers at Emory University School of Medicine have developed optochemogenetics, a combinatorial approach based on optogenetics and chemogenetics, which enables the selective, noninvasive stimulation of brain cells using light. In a mouse model...
Platinum, Blue Light Combine to Combat Cancer
COVENTRY, England, Dec. 14, 2010 — Research led by the University of Warwick has found a way to use blue light to activate what could be a highly potent platinum-based cancer treatment. The team, also consisting of researchers from Ninewells Hospital Dundee and the University...
