The treatments are effective when the healing materials are fabricated with excellent wound-healing potential. Comparatively, conventional treatments include using natural substances such as plant extracts, honey, propolis, larvae, etc. Some examples of modern and currently used treatments are stem cell therapy, oxygen therapy, nitric oxide therapy, artificial dressing, and growth factor therapy. These therapies include both conventional and modern treatments. Several therapies are available for the wound-healing process.

Multiple cell types are required within the damaged skin layers to accelerate the healing process, such as hemostasis/inflammation, angiogenesis, proliferation, and remodeling. Skin injury also occurs in daily life, where the skin loses its protective action, leading to the formation of a wound in the skin.
Wound healing is one of the most complex and essential treatments in the human body. The annual wound care costs are estimated to be several billion dollars, which constitute approximately 2–3% total expenditure on health. The accelerated wound healing was observed with CNTs-based hydrogels. CNTs-based composite hydrogels demonstrated superior antibacterial potential to corresponding pure polymer hydrogels. CNTs properties can be easily modified by surface functionalization. It has been observed that the conductivity of CNTs is profoundly affected by their structure, temperature, and functionalization. The conductive potential of CNTs and their derivatives is discussed. This review concisely discussed the preparation of CNTs-based hydrogels and their antibacterial and wound-healing applications. CNTs-based materials exhibited improved antimicrobial, antibacterial, adhesive, antioxidants, and mechanical properties, which are beneficial for the wound-healing process. CNTs-based hydrogels are widely used for wound-healing and antibacterial applications. Carbonaceous materials, including carbon nanotubes (CNTs), have been widely explored in wound healing and other applications because of their superior physicochemical and potential biomedical properties to the nanoscale level. Biocompatible nanomaterials have attracted enormous interest for biomedical applications.
