Improving the delivery of chemotherapy with graphene
A new study published in IOP Publishing's journal 2D Materials has proposed using graphene as an alternative coating for catheters to improve the delivery of chemotherapy drugs. The research suggests that placing graphene - an extremely thin sheet of carbon atoms - on the internal surfaces of intravenous catheters commonly used to deliver chemotherapy drugs into a patient's body will improve the efficacy of treatments, and reduce the potential of the catheters breaking. The study indicates...

Damaged DNA may stall patrolling molecule to initiate repair
Sites where DNA is damaged may cause a molecule that slides along the DNA strand to scan for damage to slow on its patrol, delaying it long enough to recognize and initiate repair. The finding suggests that the delay itself may be the key that allows the protein molecule to find its target, according to researchers at the University of Illinois at Chicago. Usually, the repair protein zips along quickly, says Anjum Ansari, UIC professor of physics and co-principal investigator on the study,...

Zooming in on bacterial weapons in 3-D
The plague, bacterial dysentery, and cholera have one thing in common: These dangerous diseases are caused by bacteria which infect their host using a sophisticated injection apparatus. Through needle-like structures, they release molecular agents into their host cell, thereby evading the immune response. Researchers at the Max Planck Institute for Biophysical Chemistry in Göttingen in cooperation with colleagues at the Max Planck Institute for Infection Biology in Berlin and the University of...

Shape-shifting molecule tricks viruses into mutating themselves to death
A newly developed spectroscopy method is helping to clarify the poorly understood molecular process by which an anti-HIV drug induces lethal mutations in the virus's genetic material. The findings from the University of Chicago and the Massachusetts Institute of Technology could bolster efforts to develop the next generation of anti-viral treatments. Viruses can mutate rapidly in order to adapt to environmental pressure. This feature also helps them become resistant to anti-viral drugs. But...
