Smart wound dressings, as the name suggests, are a class of wound dressings that can communicate with wounds, sense changes in the environment or in the state of the wound, and respond by using embedded sensors and/or smart materials like stimuli-responsive materials and self-healing materials.
There are many different clever wound dressings that have developed, including biomechanical wound dressings, stimuli-responsive wound dressings, self-healing wound dressings for emotional wounds, self-removable wound dressings, and monitoring wound dressings.
The Global Smart wound dressings Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
RMIT develops wound bandages with medical technology built in. The fluorescent nanosensors glow when subjected to ultraviolet (UV) light if an infection starts.
Magnesium hydroxide’s antibacterial and antifungal properties are used in multipurpose dressings to give them antimicrobial characteristics that last for up to seven days.
According to the researchers, the new dressings are equally effective against bacteria and fungi as silver-based dressings while being less costly to produce.
Currently, the only way to check on the progress of a wound’s healing is to remove the bandage dressing, which is unpleasant and risky because it leaves pathogens vulnerable to an assault.
It would be less necessary to change the dressing frequently and would help to keep wounds better protected if it could be seen quickly if something is incorrect.
With additional study, we expect that our multifunctional dressings could contribute to a new wave of inexpensive, magnesium-based technologies for cutting-edge wound care.
Magnesium’s antimicrobial, anti-inflammatory, and biocompatible qualities are well known, but there isn’t much concrete study data on how it works in medically important surfaces like bandages and dressings.
The RMIT team is the first to develop flexible fluorescent magnesium hydroxide nanosheets that could conform to the contours of bandage strands.
The nanosheets are responsive to pH variations and can therefore be used as pH-sensitive sensors to track healing.
The ability of the nanosheets to be incorporated into various biocompatible nanofibres suggests that they could be utilised with traditional cotton dressings.
In experiments carried out in the lab, it was discovered that the magnesium hydroxide nanosheets were not toxic to human cells and that they also killed newly emerging pathogens.
