Additionally, when chilled in the fridge, the dressing expands but shrinks to a smaller size at body temperature, making it easier and less painful to remove. The dressing’s thermal responsiveness allows it to warm on the skin and gently lower to room temperature. The material used to create these smart dressings includes a biopolymer derived from seaweed, a thermally responsive polymer, and cellulose nanocrystals. This dressing can provide a constant drug release outside the clinic setting, alleviating some of the challenges associated with traditional methods. In traditional chemotherapy treatment, a patient may need to be in a clinic for hours, which can be tiring and uncomfortable. The material also has applications for cancer treatment. This enables the dressing to make good contact with surfaces like noses and fingers, making it ideal for creating personalized wound dressings for burn patients. In developing the dressing, the researchers conducted a 3D scan of the patient’s face and body parts to customize it to an individual’s needs. It’s a very delicate balance within the material to make the adhesion work." "The material can easily adhere to the skin and be taken off. Boxin Zhao, a professor in Waterloo’s Department of Chemical Engineering, whose team has made significant strides in developing intelligent hydrogel materials for use as a reusable wound dressing. "To treat burn victims, we can customize the shape using a 3D printer, secondly, the material has fine-tuned surface adhesion, which is a key feature", said Dr. This new dressing could enhance the healing process for burn patients and have potential applications for drug delivery in cancer treatment as well as in the cosmetic industry. To bring relief to this and other problems, University of Waterloo researchers have created a new type of wound dressing material using advanced polymers. Researchers have developed intelligent hydrogel materials for use as a reusable wound dressing One of the challenges in treating burn victims is the frequency of dressing changes, which can be extremely painful. ![]()
