Smart Wound Protection To Visually Identify Bacteria In Minutes

The team worked with British clinicians to produce “Smartwound,” a dressing which releases a warning as soon as bacterial toxins are detected. The brains behind the technology are so confident in its ability, that they’ve created three prototypes, and say the technology within them will ward off infection in patients with both acute and chronic health issues.

Quicker diagnosis

While there are multiple signs – such as swelling, redness, and discharge – which will alert a medical professional that a wound is infected, these symptoms can take between one and three days to appear. During this time, the infection will have taken over the body, and malaise and high temperature will have set in. But the University of Bath’s new technology will cut this diagnosis time down to just minutes.

When the smartwound dressing is placed on the skin, it will dispel a harmless fluorescent dye when it comes into contact with bacteria from the wound. Meanwhile, when the scientists’ second technology prototype, a swab known as Space, is used, it will provide a positive or negative result for five key microbes in just half an hour, thanks to the phospholipid vesicles housed in the indicator solution. As a result, the relevant treatment can be given immediately.

More effective treatment

Antibiotic resistance is a growing problem throughout the world, and it’s becoming increasingly difficult to treat many common infections. As such, smartwound technology will contribute to alleviating this problem, as a definite diagnosis means unnecessary antibiotics won’t be prescribed. Furthermore, when antibiotics are required, smaller doses will be required as infections will be less severe. This smart technology is, therefore, crucial for microbial fermentation process development. This is because it will aid the development of new antibiotic drugs and will make it easier for microbiologists to obtain and isolate the relevant organism for fermentation.
