The food service industry has inspired an innovative new wound dressing.
As it stands now, the wound care industry is full of powerful dressing options. Hydrocolloid dressings, for instance, use gel to maintain the moisture around a wound site. Iodine impregnated dressings manage more complex injuries like chronic ulcers and low-level burns. Foam dressings are another common choice, and can greatly reduce patient pain and discomfort thanks to self-adhering strips. Collagen has become similarly popular for a wide array of benefits, including how it encourages major healing processes like debridement and angiogenesis.
Even with all of these dressings already available, scientists the world over are always looking for new and more effective options to help patients. Now, a team of doctors from Iran have unveiled a new wound dressing with plenty of possibilities for improving healing for people everywhere.
A More Effective Dressing
As part of a new study published in the journal Carbohydrate Polymers, the Iranian scientists have developed a special nanocomposite for use in wound dressings. The team represents the Iran Nanotechnology Initiative Council, who began their research with the goal of creating a dressing that would tackle a number of different properties, including controlling wound temperature and ensuring it could be applied and removed easily.
To achieve those goals, the researchers created the dressing with nanocellulose and antimicrobial zinc oxide nanoparticles. According to an October 2014 study in the European Polymer Journal, nanocellulose is often touted as the future of medicine and biotechnology, as it’s biodegradable and has a much lower toxicity level than some other materials. Featuring three full layers of cellulosic material, the dressing is able to release the antimicrobial particles in several increments, allowing for a much more through treatment of the wound.
The dressing’s design was inspired in part by the food industry, according to the Digital Journal. Specifically, the dressing features what’s called an “active pack,” which helps seal off the wound from the outside environment and prevent any harmful bacteria from entering.
The dressing has already undergone several rounds of experimentation. The Iranian team found the dressing can block out several different strands of fungi and bacteria and was most effective when paired with a bandage to further seal off the wound. More tests will follow, but this dressing could represent another effective option for people with any number of wound types.
