Abstract
Carbon nanotubes (CNTs) possess unique physicochemical properties that are suitable for a variety of uses in manufacturing, environmental, and biomedical applications, as well as in the food and agriculture industries. The uses and manufacturing of CNTs are increasing due to advances in the large-scale production of CNTs and the development of various CNT-added composites. The antimicrobial activities and potential applications of CNTs and CNT-based materials as antimicrobials have recently attracted great interest. In this mini review, we first introduce the commonly seen nanotechnology-based antimicrobial materials, especially carbon-based nanomaterials such as CNTs, fullerenes, and graphene. Next, the history of the antimicrobial studies of CNTs is briefly described, followed by an overview of CNT toxicity. The antimicrobial properties of single-walled and multi-walled CNTs and the antimicrobial mechanisms of CNTs are summarized and discussed. The future challenges and potential applications of CNTs in bone tissue engineering and antimicrobial applications are provided.
