CHALLENGES WITH EXISTING DRESSING MATERIALS Before developing advanced wound care materials, researchers must examine the shortcomings of present wound dressings.

8.1 Adherence Dressings with an adhesive layer allow them to stick to undamaged skin, but they must be removed carefully because the adhesive might harm the epidermal skin, resulting in pain and the possibility of hypersensitivity. Non-adherent dressings should be applied to the wound to offer an interface with the secondary dressing in order to promote quick and painless removal.212

8.2 Opaque The majority of wound dressings available in the market are typically opaque. As a result, visual examination of the process of recovery is prohibited. With opaque dressings, infection or other problems are difficult to detect. Removal of dressing during examination not only causes irritation but also disturbance in healing which can cause bleeding and inflammation. As a result, transparent dressings will be preferable. Transparent adhesive free dressings with antiseptic which can be quickly absorbed by wound are especially attractive because, rather than removing, a similar transparent self-adhering dressing could be applied forthwith after the preceding one has been absorbed.213

8.3 Low degradation rate Some wound dressing has a low degradation rate, which can prolong antibiotic release at the wound site; consequently, these can be combined with polymers having a higher degradation rate to tune the degradation process.214

8.4 Multifunctionality It is a challenge to monitor the wound bed properties like pH or temperature. Such criteria have the potential to reflect wound healing progress and must be examined carefully. Different types of biosensors must be incorporated into wound dressings for this objective, and an updated series of sophisticated devices capable of real-time sensing and monitoring of wound conditions should be developed. As a result, multifunctional dressings that can manage multiple types of infected wounds while significantly reducing infection risk are required as an all-in-one solution. A wound dressing that addresses these problems ensures not only rapid wound healing but also prevents infection. Furthermore, the therapeutic cycle and duration may be anticipated and managed over time
