The next step for Zhao's research group is to continue improving the material's properties to make it healthier and commercially viable.
This research is proof of concept for Zhao's Surface Science and Bio- nanomaterials Laboratory Group. Additionally, this innovative approach can benefit plastic surgeons." "Cosmetologists can utilize 3D scanning technology to analyze their clients' facial features and customize hydrogel masks infused with specific facial and skin regimen products. "We also envision applications in the beauty and cosmetic industry," adds Zhao, Waterloo's Endowed Chair in Nanotechnology. Also, the dressing is designed to provide time-release medication, allowing for longer-lasting pain relief. The dressing's thermal responsiveness allows it to warm on the skin and gently lower to room temperature.Īdditionally, 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 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. 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. To develop 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, in a news release. "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," explains Dr. A new handheld 3D printer can deposit sheets of skin to cover large burn wounds - and its 'bio ink' can accelerate the healing process. A 3D-printed wound dressing that uses advanced polymers may enhance the healing process for burn patients, aid drug delivery in cancer treatment, and help customize skin care regimens.
