The Latest Smart Wound Dressings

Introduction: Smart wound dressings have emerged as a solution to the spread of infectious wounds and complications in their recovery. These dressings can sense and respond to changes in the environment, release medicine at the wound site, and use fluorescent molecular probes and colored light analysis to determine the extent of infection and damage. Additionally, wearable wireless sensors, biodegradable metal electrodes, and laser-induced graphene are being used to create innovative and effective smart wound dressings. The use of colorimetric sensors in wound dressings for detecting blood glucose in diabetic patients, along with growth factor releasing components, has also been successful in wound healing and infection control.Method: Researchers have developed a two-layer smart wound dressing that can detect temperature, pH, and uric acid levels at the wound site, and release antibiotics when needed. The dressing utilizes sensors and a wireless connection to a smartphone to monitor and control the wound environment. This information is taken from Elsevier,Pubmed, Research Gate databases.Result: Recent studies have found that smart dressings, such as pH-sensitive and heat-sensitive dressings, are more effective in treating wounds and preventing infection compared to traditional dressings. Additionally, colorimetric sensors used in diabetic patients can not only measure blood glucose levels but also aid in healing scars and reducing infection through temperature-sensitive sensors and controlled drug delivery.conclusion: Smart dressings have helped a lot in treating and improving wound control. The emergence of biodegradable dressings has helped to protect the environment. The presence of moisture in the wound area as well as very high or sub-zero temperatures may endanger the sensitivity of the sensors.
