Carbon Nanotubes-Based Hydrogels for Bacterial Eradiation and Wound-Healing Applications

Biocompatible nanomaterials have attracted enormous interest for biomedical 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. CNTs-based hydrogels are widely used for wound-healing and antibacterial applications. CNTs-based materials exhibited improved antimicrobial, antibacterial, adhesive, antioxidants, and mechanical properties, which are beneficial for the wound-healing process. This review concisely discussed the preparation of CNTs-based hydrogels and their antibacterial and wound-healing applications. The conductive potential of CNTs and their derivatives is discussed. It has been observed that the conductivity of CNTs is profoundly affected by their structure, temperature, and functionalization. CNTs properties can be easily modified by surface functionalization. CNTs-based composite hydrogels demonstrated superior antibacterial potential to corresponding pure polymer hydrogels. The accelerated wound healing was observed with CNTs-based hydrogels.

Automated summary

Biocompatible nanomaterials, particularly carbon nanotubes (CNTs), have superior antimicrobial, adhesive, and mechanical properties that make them suitable for wound-healing and antibacterial applications. The conductivity of CNTs is significantly influenced by their structure, temperature, and functionalization, while surface functionalization can easily modify their properties to enhance antibacterial potential.
