A revolutionary new medical device is about to hit the market: a microneedle array embedded with ultrasound-triggered antibacterial agents. This device, developed by a research team at the University of Alberta, could revolutionize the way we treat bacterial infections. The device works by embedding an array of microneedles into the skin, which contain an antibacterial agent. When exposed to ultrasound, the agent is triggered, releasing the drug into the skin to fight the infection. By using ultrasound to trigger the drug release, the team was able to ensure that the drug is delivered in a controlled and targeted manner, eliminating the need for invasive surgery or painful injections. This could be a major breakthrough in the fight against bacterial infections, offering a safe, effective, and minimally-invasive solution.
