Abstract:	Background: Wound healing is a complex and dynamic process involving the replacement of devitalized and missing cellular structures and tissue layers. Methods: This study involved developing a drug-loaded biomimetic micropillar wound dressing based upon inspiration from witnessing the adhesive ability in a gecko's footpad. The conformal adhesion was set up by applying a soft elastomer thin film on the developed wound dressing surfaces. The results showed that the developed surfaces prepared based on polydimethylsiloxane (PDMS) had low surface free energy, high chemical stability, and good plasticity. Astaxanthin (AST) and curcumin were applied as the patch's bioactive compounds to help accelerate the wound healing process. Results: The results showed that the developed surfaces prepared based on polydimethylsiloxane (PDMS) had low surface free energy, high chemical stability, and good plasticity. Astaxanthin (AST) and curcumin were applied as the patch's bioactive compounds to help accelerate the wound healing process. The results indicate that the developed biomimetic micropillar patches could release the loaded drugs and significantly increase cell viability and collagen content to 20 % ∼ 25 % in vitro and in vivo. Conclusion: In summation, the primary purpose of this study has been to design a novel encapsulated carrier (micropillar patch) for use in adjustable drug release, while combining with the biomimetic microstructure to reach wound healing through percutaneous absorption.
