Professor Emeritus Dave Worley develops cost-effective, staph-resistant bandage

05/22/2017

Staph infections affect thousands of people each year, often occurring as a person recovers from surgery or a wound. But an Auburn University professor has developed a better bandage that could keep people from becoming infected. Professor Emeritus Dave Worley of the Department of Chemistry and Biochemistry in the College of Sciences and Mathematics is applying his patented N-halamine chemistry to gauze bandages to kill any bacteria that might contact a wound. “A 2-inch-square bandage would cost only 3-4 cents more than a regular bandage,” Worley said. “We tested it on Staphylococcus aureus and Pseudomonas aeruginosa. It kills them before they can infect the wound. Once a person becomes infected, the bacteria are hard to kill, especially if they are resistant to antibiotics.” Worley’s process works by soaking the gauze in a solution of alcohol and an N-halamine compound containing chlorine. When the alcohol evaporates, the remaining solid, bacteria-killing compound adheres electrostatically to the bandage. “You can shake the bandage, but the compound won’t come out,” said Worley, who says current bandages with silver also kill bacteria, but they are costly at up to $500 each. “We are at least as effective as silver at only a fraction of the cost.” Worley’s research shows that N-halamine bandages should be kept away from light prior to use. “Our stability is good if you keep the bandages in opaque packages,” he said. “Most wound dressings are replaced every one to two days, so ours are effective throughout the time they are worn.”

COSAM to present Comer Awards

05/04/2017

The Comer Medal was established in 1923 by former governor Braxton Bragg Comer to recognize the most outstanding student in the natural sciences. Beginning in 1924, a single medal was given annually until 1970, when it was decided that two medals, one in the physical sciences and one in the biological sciences, would be awarded each year. In 1989, it was decided that a third Comer Medal would be presented each year to a student in the field of agriculture.
