# Carbon Nanotubes-Based Hydrogels for Bacterial Eradiation and Wound-Healing Applications
## 6 Conclusions and Future Perspective  
The application of carbon nanotubes and metal nanoparticles could be considered a promising approach for disinfection purposes. In this review, we summarized the studies related to the design and current strategies for developing CNT hydrogel wound-healing applications. CNT hydrogel composites with conductive and antibacterial properties have been considered as a promising candidate in wound healing and antibacterial treatment due to their excellent electrical and mechanical properties. Advances in the research and development toward the development of multifunctional hydrogels composites using different strategies have been contributing to establish more effective devices for wound-healing applications and enable bringing out effective skin regenerations. However, few obstacles, including low drug resistance, low antibacterial properties, toxicity, and low physical strength, are associated with the hydrogel composites. Thus, CNT hydrogels with antibacterial agents and hydrogel matricesare adopted to solve these issues. However, the diversity of wound healing requires hydrogel composite materials with multifunction to resist infections in or around the wound, enabling an effective and fast healing process. In this contest, CNT hydrogel with multifunctionality (pH-responsive, self-healing hydrogel, conductive hydrogel) needs to be developed to meet the requirements of different wound environments and types to heal it efficiently. Hence, future research should explore more advanced strategies to design efficient hydrogel composite materials with null toxicity.CNTmultifunctional hydrogels will be more attractive wound-healing materials. These composites should possess certain advantages such as easy synthesis procedures, large-scale compatibility, economic viability, degradability, and ready availability. These sustainable aspects should be considered for the further development of CNT-based hydrogels. In addition to CNT hydrogel's potential efficiency in wound healing and other biomedical applications, a few necessary research fields need to be addressed in the near future, such as (i) significant studies to understand the toxicity issues related to CNT hydrogel and developing the strategies to overcome these issues, (ii) the development of a multifunctional hydrogel hybrid composite as well as devices (patches in the form of nasal, ocular, oral, intrathecal) for an efficient recovery, (iii) research on the implementation and working mechanism of CNT hydrogel for the complete wound-healing process, (iv) sensing or detection of interacted hydrogel materials to confirm the progress of treatment, and (v) studies related to the hydrogel effect on inflammation and wound site recovery. More importantly, significant studies should be conducted on the applicability of CNT hydrogel materials to check their potential for other innovative biomedical applications such as tissue engineering, organ replacement, biosensing devices, DNA identifications, micro chemotaxis devices, cardiac construction, etc. Conceptualization, T.V.P., writing-original draft, T.V.P., S.D.D., K.G., A.R., writing-review and editing, D.K.P., Supervision, K.-T.L., funding acquisition, K.-T.L.
