Doctors, engineers, and AI experts are teaming up to develop “smart bandages” capable of treating chronic wounds, battlefield injuries, or even minor cuts and scrapes.
“Wound care — even with all of the billions of products that are sold — still exists on kind of a medieval level,” said Geoffrey Gurtner, MD, chair of the department of surgery and professor of biomedical engineering at the University of Arizona College of Medicine. “We’re still putting on poultices and salves ... and when it comes to diagnosing infection, it’s really an art. I think we can do better.
Others in development could halt a battlefield wound from hemorrhaging or kick-start healing in a blast wound, preventing longer-term disability. They could also save the health care system money, as the U.S. spends more than $28 billion annually treating chronic“This is a condition that many patients find shameful and embarrassing, so there hasn’t been a lot of advocacy,” said Gurtner, outgoing board president of the Wound Healing Society. “It’s a relatively ignored problem afflicting an underserved population that has a huge cost. It’s a perfect storm.”First platelets rush to the injury, prompting blood to clot.
Checking for infection means removing bandages and culturing the wound. That can be painful, and results take time.“Sometimes, they come back and it’s a disaster and they have to be admitted to the ER or even get an amputation,” Gurtner said. “It’s kind of a race to the finish,” said Marco Rolandi, PhD, associate professor of electrical and computer engineering at the University of California Santa Cruz and the principal investigator for a team including engineers, medical doctors, and computer scientists from UC Santa Cruz, UC Davis, and Tufts. “I’ve been amazed and impressed at all the work coming out.”

Novel molecular design for enhanced efficacy and safety in radiotheranosticsRadiotheranostics embodies the convergence of diagnostic and therapeutic radiopharmaceuticals into a unified platform. In cancer treatment, radiotheranostic procedures typically involve the use of antibodies that bind to proteins abundantly found on the surface of cancerous cells. The antibodies are labeled with a suitable radioisotope, which facilitates imaging procedures used to diagnose cancer and can be used to target cancerous cells and bombard them with deadly radiation as a form of treatment.
