“…The antibacterial activity of all prepared electrospun Polyamide6 / Chitosan, Polyamide6 Also, the results show that the three filters antibacterial activity was better for gram positive bacteria in comparison with gram negative bacteria. This maybe explain by the differences in the cell membrane components of these bacteria and this agree with [22] results and did not agree with [8].…”

With the fast development of nanotechnology, the preparation of electrospun nanofibers received increasing interest. Because of their large specific area and superior functional abilities, electrospun nanofiber membranes play an essential role in various fields, particularly in wastewater treatment. The goal of this study is to develop bacterial rejection membranes of Polyamide6/Chitosan nanofiber membranes that have pores larger than some bacterial cell types present in wastewater. Polyamide6/ Chitosan nanofiber membranes were prepared by electrospinning technique. The fabricated filters were characterized using Field emission scanning electron microscopy (FeSEM), water contact angle assessment. The diameters of nanofibers in the range of (116.88 237.34) nm were achieved. The bacterial removal efficiency of Polyamide6/ Chitosan nanocomposites on coliform and streptococci were studied. The results showed that Polyamide6/ Chitosan/1.5% Zinc Oxide nanoparticles, and (20 25) min. of reaction time resulted in the best removal efficiency: 99 % for coliform and 99.99 % for Streptococci. The bacterial cells were entrapped and damaged after passing through the membrane, as seen by Fe SEM images. As a result, these PA6/ Chitosan nanocomposites membranes appear promising for decontamination of water.

Nanotechnology is one of the most emerging fields of research within recent decades and is based upon the exploitation of nano-sized materials (e.g., nanoparticles, nanotubes, nanomembranes, nanowires, nanofibers and so on) in various operational fields. Nanomaterials have multiple advantages, including high stability, target selectivity, and plasticity. Diverse biotic (e.g., Capsid of viruses and algae) and abiotic (e.g., Carbon, silver, gold and etc.) materials can be utilized in the synthesis process of nanomaterials. "Nanobiotechnology" is the combination of nanotechnology and biotechnology disciplines. Nano-based approaches are developed to improve the traditional biotechnological methods and overcome their limitations, such as the side effects caused by conventional therapies. Several studies have reported that nanobiotechnology has remarkably enhanced the efficiency of various techniques, including drug delivery, water and soil remediation, and enzymatic processes. In this review, techniques that benefit the most from nano-biotechnological approaches, are categorized into four major fields: medical, industrial, agricultural, and environmental.

Bacterial strains resistant to antimicrobial treatments, such as antibiotics, have emerged as serious clinical problems, necessitating the development of novel bactericidal materials. Nanostructures with particle sizes ranging from 1 to 100 nanometers have appeared recently as novel antibacterial agents, which are also known as “nanoantibiotics”. Nanomaterials have been shown to exert greater antibacterial effects on Gram-positive and Gram-negative bacteria across several studies. Antibacterial nanofilms for medical implants and restorative matters to prevent bacterial harm and antibacterial vaccinations to control bacterial infections are examples of nanoparticle applications in the biomedical sectors. The development of unique nanostructures, such as nanocrystals and nanostructured materials, is an exciting step in alternative efforts to manage microorganisms because these materials provide disrupted antibacterial effects, including better biocompatibility, as opposed to minor molecular antimicrobial systems, which have short-term functions and are poisonous. Although the mechanism of action of nanoparticles (NPs) is unknown, scientific suggestions include the oxidative-reductive phenomenon, reactive ionic metals, and reactive oxygen species (ROS). Many synchronized gene transformations in the same bacterial cell are essential for antibacterial resistance to emerge; thus, bacterial cells find it difficult to build resistance to nanoparticles. Therefore, nanomaterials are considered as advanced solution tools for the fields of medical science and allied health science. The current review emphasizes the importance of nanoparticles and various nanosized materials as antimicrobial agents based on their size, nature, etc.
