Advances in Smart Bioactive Surfaces for Wounding Healing and Tissue Repair

Biomaterials and implantable/interventional medical devices play an irreplaceable role in saving human life and promoting human health. Their surface properties and functions largely determine their clinic performances after the implantation. The introduction of the bioactive factors on the surfaces to design the surface biological function and construct the surface microenvironment, so as to further endow the surfaces with the ability to in-situ regulate the physiological microenvironment responses, can effectively promote wound healing and tissue repair and regeneration after the implantation. In particular, by constructing the smart bioactive surfaces on the implant surfaces that can not only mimics the in vivo three-dimensional microenvironment but also promote and induce wound healing and tissue repair through the in vivo physiological environment after the implantation, the implant can be endowed with the multi-functional ability to actively adapt to and regulate the interfacial physiological responses, so as to better promote wound healing and tissue repair and regeneration.

The current Research Topic mainly focuses on the most recent advances in smart bioactive surfaces for wounding healing and tissue repair, which can be potentially used in the clinic biomaterials and implants. Typically, the methods for fabricating the smart bioactive surfaces, the three-dimension smart hydrogel coating, the newly synthesized bioactive molecules for the smart bioactive surfaces, stimuli-responsive surfaces for wounding healing and tissue repair, etc, which can offer innovative insights and perspectives for the development of this interdisciplinary area, will be emphasized.
