“…The Arenas-Arrocena group synthesized Fe x−1 S NPs and reported their antibacterial and cytotoxic activity in 2018. Antibacterial activity against S. aureus, E. coli and E. faecalis was observed (Argueta-Figueroa et al, 2018 ). In addition, Gao and coworkers discovered antibacterial inorganic iron polysulfides materials that were converted by organosulfur compounds in 2018.…”

Nano-sized iron sulfides have attracted intense research interest due to the variety of their types, structures, and physicochemical properties. In particular, nano-sized iron sulfides exhibit enzyme-like activity by mimicking natural enzymes that depend on an iron-sulfur cluster as cofactor, extending their potential for applications in biomedicine. The present review principally summarizes the synthesis, properties and applications in biomedical fields, demonstrating that nano-sized iron sulfides have considerable potential for improving human health and quality of life.

“…This finding indicated that the PVP was successfully converted into the carbon under inert atmosphere during the carbonization process. Additionally, the peaks at 2θ values of 30.3 and 43.6 • corresponding to the (200) and (2010) planes of Fe 1−x S were observed (JCPDS # 29-0724) [25,26]. The selected area electron diffraction (SAED) in the inset in Figure 2C also shows the polycrystalline nature of the prepared sample.…”

Fe1−xS-TiO2 nanoparticles embedded carbon nanofibers (Fe1−xS-TiO2/CNFs) composite as a supercapacitor electrode material has been reported in the present work. The Fe1−xS-TiO2/CNFs composite was fabricated by electrospinning technique followed by carbonization under argon atmosphere and characterized by the state-of-art techniques. The electrochemical studies were carried out in a 2 M KOH electrolyte solution. The synthesized material showed a specific capacitance value of 138 F/g at the current density of 1 A/g. Further, the capacitance retention was about 83%. The obtained results indicate that the Fe1−xS-TiO2/CNFs composite can be recognized as electrode material in supercapacitor.

“…In terms of ROS permeability of bacterial cell membrane, it is found that both Gram-positive and Gram-negative bacteria are equally permeable to ROS [116], the only difference being in ROS intracellular effects. Superoxide and H 2 O 2 species are generated in the cytoplasm as a result of oxygen interaction with redox enzymes possessing flavin groups [124].…”

Along with the extensive range of exotic nanoparticle (NPs) applications, investigation of magnetic NPs (MNPs) in vitro has ushered modern antibacterial studies into an increasingly attractive research area. A great number of microorganisms exist in the size scales from nanometre to micrometre regions. The enormous potential of engineered MNPs in therapeutic procedures against various drug-resistant bacteria has declined the menace of fatal bacterial infections. Many biocompatible MNPs have been introduced that possess remarkable impacts on various bacterial strains. Conventional synthesis methods such as co-precipitation or hydrothermal techniques have been widely adopted in the production of MNPs. The MNPs for antibacterial applications are mainly required to be superparamagnetic, recyclable and biocompatible. To implement novel strategies in developing new generation antimicrobial magnetic nanomaterials, it is essential to obtain a comprehensive preview of recent achievements in synthesis, proposed antibacterial mechanisms and characterisation techniques of these nanomaterials. This review highlights notable aspects of antibacterial activity in engineered MNPs and nanocomposites including their particle properties (size, shape and saturation magnetisation), antibacterial mechanisms, synthesis methods, testing methods, surface modifications and minimum inhibitory concentrations.
