Abstract

The increase in antimicrobial resistance (AMR) poses a massive threat to world health, necessitating the urgent development of alternative antimicrobial growth control techniques. Due to their specific physical and chemical properties, nanomaterials, particularly carbon-based nanomaterials, have emerged as attractive candidates for antimicrobial applications, however, reviews are lacking. This comprehensive review aims to bridge the existing knowledge gaps surrounding the mechanism and significance of nanobiochar (NBC) and carbon nanostructures in the field of antimicrobial applications. Notably, NBC, which is derived from biochar, exhibits promising potential as an environmentally-friendly substance with antimicrobial properties. Its strong adsorption capabilities enable the removal and immobilization of pathogens and pollutants from soil and water and also exhibit antimicrobial properties to combat harmful pathogens. In addition to NBC, carbon dots (CDs) and graphene oxide (GO) have also shown excellent antimicrobial properties. These carbon-based nanomaterials find applications in agriculture for phytopathogen control and post-harvest disease management, as well as in medicine for nanotheranostics and in the food industry for extending shelf life as an eco-friendly alternative to chemicals and antibiotics. However, the long-term toxicity of these nanoparticles to humans and the environment needs further investigation, considering the influence of different physiochemical characteristics on antimicrobial properties and nanotoxicity. Therefore, continued exploration in this area will pave the way for future research and safe deployment strategies of carbon-based nanomaterials in combating microbial threats.

碳纳米结构抗菌活性的当前趋势:与碳点相比,纳米生物炭的潜力和现状
摘要 抗菌剂耐药性(AMR)的增加对世界健康构成了巨大威胁,因此迫切需要开发替代性抗菌剂生长控制技术。由于其特殊的物理和化学特性,纳米材料,尤其是碳基纳米材料,已成为抗菌应用的有吸引力的候选材料,但目前还缺乏相关综述。本综述旨在弥合纳米生物炭(NBC)和碳纳米结构在抗菌应用领域的机理和意义方面的现有知识差距。值得注意的是,从生物炭中提取的 NBC 作为一种具有抗菌特性的环境友好型物质,具有广阔的发展前景。它具有很强的吸附能力,能够清除和固定土壤和水中的病原体和污染物,还具有抗菌特性,可对抗有害病原体。除 NBC 外,碳点(CD)和氧化石墨烯(GO)也具有出色的抗菌性能。这些碳基纳米材料可应用于农业领域的植物病原体控制和收获后疾病管理,也可应用于医药领域的纳米otheranostics,以及食品工业领域的延长保质期,作为化学品和抗生素的环保型替代品。然而,考虑到不同理化特性对抗菌特性和纳米毒性的影响,这些纳米粒子对人类和环境的长期毒性还需要进一步研究。因此,在这一领域的持续探索将为碳基纳米材料在应对微生物威胁方面的未来研究和安全部署战略铺平道路。 图表摘要
