(Feb.9, '15) Rice-led study shows how particles quench damaging
superoxides
Injectable nanoparticles that could protect an injured
person from further damage due to oxidative stress have proven to be
astoundingly effective in tests to study their mechanism.
Scientists at Rice University, Baylor College of Medicine
and the University of Texas Health Science Center at Houston (UTHealth) Medical
School designed methods to validate their 2012 discovery that combined
polyethylene glycol-hydrophilic carbon clusters — known as PEG-HCCs — could
quickly stem the process of overoxidation that can cause damage in the minutes
and hours after an injury.
