“…13 d. Also, further works reveal the death of bacteria was due to the loss of their membrane integrity after the membrane integrity assay displayed the fluorescent intensity of PI dye following their penetrations into the membrane of damaged and slightly damaged bacteria Fig. 13 e. PI is capable of penetrating such membranes other than those unaffected or intact membranes [ [168] , [169] , [170] ]. Thus, exposure to K3 resulted in the loss of membrane integrity and subsequently bacterial cell death.…”

“…The contribution of PDA to provide stability as an adhesive and antibacterial activity has been validated during evaluation of PDA/alginate/Fe 3 O 4 hydrogel beads. The coating of PDA on to Alg/Fe 3 O 4 beads not only significantly increased the stability in different pH, hydrophilicity, and elasticity but also performed strongly against bacterial strains ( Matai et al, 2019 ). These beads have been demonstrated to be used repeatedly as antibacterial agents.…”

The drug resistance developed by bacteria during antibiotic treatment has been a call to action for researchers and scientists across the globe, as bacteria and fungi develop ever increasing resistance to current drugs. Innovative antimicrobial/antibacterial materials and coatings to combat such infections have become a priority, as many infections are caused by indwelling implants (e.g., catheters) as well as improving postsurgical function and outcomes. Pathogenic microorganisms that can exist either in planktonic form or as biofilms in water-carrying pipelines are one of the sources responsible for causing water-borne infections. To combat this, researchers have developed nanotextured surfaces with bactericidal properties mirroring the topographical features of some natural antibacterial materials. Protein-based adhesives, secreted by marine mussels, contain a catecholic amino acid, 3,4-dihydroxyphenylalanine (DOPA), which, in the presence of lysine amino acid, empowers with the ability to anchor them to various surfaces in both wet and saline habitats. Inspired by these features, a novel coating material derived from a catechol derivative, dopamine, known as polydopamine (PDA), has been designed and developed with the ability to adhere to almost all kinds of substrates. Looking at the immense potential of PDA, this review article offers an overview of the recent growth in the field of PDA and its derivatives, especially focusing the promising applications as antibacterial nanocoatings and discussing various antimicrobial mechanisms including reactive oxygen species-mediated antimicrobial properties.

“…MNPs have been widely used in the biological field in recent years due to their physical properties, good biocompatibility, and high binding capacity [8][9][10], including in vivo and in vitro bacterial detection and separation imaging [11], as well as the treatment of pathogenic bacteria. For example, magnetic materials were used to synthesize new structures [12] and new magnetic material composite nanoparticles with improved structural stability [13], biological activity [14], and antibacterial properties [15][16][17][18] to realize the separability and recyclability of MNPs [19][20][21].…”

Infections caused by pathogenic bacteria, especially multidrug-resistant bacteria, have become a serious worldwide public health problem. Early diagnosis and treatment can effectively prevent the adverse effects of such infections. Therefore, there is an urgent need to develop effective methods for the early detection, prevention, and treatment of diseases that are caused by bacterial infections. So far, magnetic material nanoparticles (MNPs) have been widely used in the detection and treatment of bacterial infections as detection agents and therapeutics. Therefore, this review describes the recent research on MNPs in bacterial detection and treatment. Finally, a brief discussion of challenges and perspectives in this field is provided, which is expected to guide the further development of MNPs for bacterial detection and treatment.
