Monoolein-Alginate Beads as a Platform to Promote Adenosine Cutaneous Localization and Wound Healing

In the 2017 study, researchers developed monoolein-alginate beads to manage wet wounds by absorbing excess fluid and releasing adenosine to promote healing. These beads were larger, had a higher swelling ability, and released less adenosine after 24 hours compared to alginate-only beads. They were safe for topical use, as they did not affect the viability of reconstructed skin. The beads delivered adenosine more effectively to the viable skin layer, indicating better cutaneous localization, which is crucial for wound healing. The study concluded that these beads are a promising method for localized drug delivery in wound management, potentially extending to other skin conditions like psoriasis and androgenetic alopecia.
