Smart bioactive hydrogel-based films loaded with nanoparticles for wound healing

Nanoscale smart bioactive hydrogel-based films for wound healing are advanced materials designed to promote efficient and effective wound healing. These films are composed of hydrogels, which are three-dimensional (3D) networks of hydrophilic polymers capable of retaining large amounts of water or biological fluids. The nanoscale size refers to the small dimensions of the structures and particles incorporated within the hydrogel matrix. The key characteristic of these films is their “smart” nature, which means they possess responsive properties that can be triggered by specific stimuli or conditions. This responsiveness allows the films to actively interact with the wound environment and facilitate the healing process. Various components can be incorporated into the hydrogel matrix to achieve these functionalities. Here are some important features and components of nanoscale smart bioactive hydrogel-based films for wound healing. Firstly, nano-sized particles, such as nanoparticles or nanocapsules, can be embedded within the hydrogel matrix. These particles can carry therapeutic agents, such as growth factors, antimicrobial agents, or antiinflammatory drugs. The hydrogel matrix acts as a reservoir, gradually releasing the loaded substances into the wound bed, thereby providing sustained and controlled drug delivery. Secondly, nanoparticles or bioactive molecules can be incorporated into the hydrogel matrix to provide specific cues that promote cell adhesion, migration, and proliferation. This chapter provides key insights into nanoscale smart bioactive hydrogel-based films that offer a versatile platform for advanced wound healing and articulates the clinical potential of these films and their translation into clinical practice for the benefit of patients with various types of wounds.
