Researchers Advance Work to Fight Antibiotic Resistance with NSF Grant

Researchers at the University of Arkansas have received a grant of $498,983 from the National Science Foundation to study the anti-microbial mechanisms of silver nanoparticles to look for ways these nanoparticles could be used to fight antibiotic-resistant infections. Yong Wang, assistant professor of physics, and Jingyi Chen, associate professor of physical chemistry, are working with Mark Smeltzer, professor of microbiology and immunology at the University of Arkansas for Medical Sciences. They will use an advanced imaging technique called super resolution fluorescence microscopy, which can achieve a resolution of 20 nanometers—10 times more powerful than conventional light microscopes—to observe the...

Researchers Develop Method for Identifying Radiation-Resistant Tumors

New research at the University of Arkansas has found a way to identify radiation-resistant cancer cells, a breakthrough in the treatment of lung cancer that uses imaging to evaluate the response to treatment and match treatment to specific tumor cells. Until now, there has been no way to determine immediately after beginning therapy if a tumor is resistant to radiation therapy or not. The findings were published this month in Scientific Reports, a Nature journal. “Our results demonstrate that the use of autofluorescence imaging of cell metabolism can identify treatment-resistant cancer cells,” said Narasimhan Rajaram, assistant professor of biomedical...
