A biofilm is an aggregation of surface-associated microbial cells that is confined in an extracellular polymeric substance (EPS) matrix. Infections caused by microbes that form biofilms are linked to a variety of animals, including insects and humans. Antibiotics and other antimicrobials can be used to remove or eradicate biofilms in order to treat infections. However, due to biofilm resistance to antibiotics and antimicrobials, clinical observations and experimental research clearly demonstrates that antibiotic and antimicrobial therapies alone are frequently insufficient to completely eradicate biofilm infections. Therefore, it becomes crucial and urgent for clinicians to properly treat biofilm infections with currently available antimicrobials and analyze the results. Numerous biofilm-fighting strategies have been developed as a result of advancements in nanoparticle synthesis with an emphasis on metal oxide np. This review focuses on several therapeutic strategies that are currently being used and also those that could be developed in the future. These strategies aim to address important structural and functional aspects of microbial biofilms as well as biofilms' mechanisms for drug resistance, including the EPS matrix, quorum sensing (QS), and dormant cell targeting. The NPs have demonstrated significant efficacy against bacterial biofilms in a variety of bacterial species. To overcome resistance, treatments such as nanotechnology, quorum sensing, and photodynamic therapy could be used.
生物膜是一种与表面相关的微生物细胞聚集体,被限制在细胞外聚合物(EPS)基质中。由形成生物膜的微生物引起的感染与包括昆虫和人类在内的多种动物有关。抗生素和其他抗菌剂可用于去除或根除生物膜以治疗感染。然而,由于生物膜对抗生素和抗菌剂具有抗性,临床观察和实验研究清楚地表明,仅使用抗生素和抗菌疗法往往不足以完全根除生物膜感染。因此,临床医生正确使用现有抗菌剂治疗生物膜感染并分析结果变得至关重要和紧迫。由于纳米颗粒合成技术的进步,特别是金属氧化物纳米颗粒的发展,已经开发出许多对抗生物膜的策略。本综述重点关注目前正在使用的几种治疗策略以及未来可能开发的策略。这些策略旨在解决微生物生物膜的重要结构和功能方面以及生物膜的耐药机制,包括EPS基质、群体感应(QS)和休眠细胞靶向。纳米颗粒已在多种细菌物种中显示出对细菌生物膜的显著疗效。为了克服耐药性,可以使用纳米技术、群体感应和光动力疗法等治疗方法。
