“…Contact-killing surfaces are specifically engineered to elicit a stress response in bacteria upon interaction, leading to cell death. These surfaces can employ various tethered antibacterial agents including nanodiamonds, AmPs, − antimicrobial polymers, small molecules, and NPs. − Optimized shape, orientation, and material properties can also facilitate puncturing of bacterial cell membranes . Other surface modifications utilize ionic interactions to create disturbances in the bacterial membrane.…”

“…Other surface modifications utilize ionic interactions to create disturbances in the bacterial membrane. These ionic interactions can be facilitated through AmP brushes, interactions with antimicrobial polymers in coatings such as poly- l -lysine, ,, or coatings with embedded salts and metals. , Adsorption and fouling of nonmicrobial content including host proteins and stimulation of the foreign body response, however, can reduce the antibacterial properties of many existing coatings. , Changing coating composition and improving fabrication to reduce defects can help overcome this limitation.…”

Bacterial infections are a major threat to human health, exacerbated by increasing antibiotic resistance. These infections can result in tremendous morbidity and mortality, emphasizing the need to identify and treat pathogenic bacteria quickly and effectively. Recent developments in detection methods have focused on electrochemical, optical, and mass-based biosensors. Advances in these systems include implementing multifunctional materials, microfluidic sampling, and portable data-processing to improve sensitivity, specificity, and ease of operation. Concurrently, advances in antibacterial treatment have largely focused on targeted and responsive delivery for both antibiotics and antibiotic alternatives. Antibiotic alternatives described here include repurposed drugs, antimicrobial peptides and polymers, nucleic acids, small molecules, living systems, and bacteriophages. Finally, closed-loop therapies are combining advances in the fields of both detection and treatment. This review provides a comprehensive summary of the current trends in detection and treatment systems for bacterial infections.

A nanocomposite containing imidazolium based on modified silica nanoparticles (polyimidazolium based on nano silica particles [PIZNS]) was prepared to remove nitrate from water. The prepared compounds were fully characterized by Fourier transform infrared, 1 H-NMR, field emission scanning electron microscopy, energy dispersive X-ray (EDX) and thermogravimetric analyzes. The ability of PIZNS in nitrate ions adsorption was tested under different operating conditions. The maximum removal efficiency and adsorption capacity (Q max ) of the PIZNS were obtained 90.56% and 37.73 mg g À1 , respectively (initial nitrate ion concentration of 50 mg/L, at pH = 7, 30 mg adsorbent, contact time of 30 min).

A series of gentamicin‐modified anion exchange membranes (AEMs) immobilized by mussel‐inspired dopamine coating is prepared in this work. The purpose is to improve antibacterial activity and fouling resistance of the commercial AEMs (AEM Type I, Fujifilm Co.). As a result of the applied modification, the hydrophilicity of membrane surface improved significantly. Thus, the as‐prepared modified AEMs exhibit the good antifouling property, in electrodialysis (ED) experiments by using the sodium dodecylbenzenesulfonate and albumin from bovine serum as model foulants. Furthermore, taking into account the results of the antibacterial test, the resulting modified AEMs exhibit improved antibacterial property for Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). After a brief contact with bacteria, the antibacterial rates of modified AEMs coating with gentamicin‐based polymer are 80.11% for E. coli and 90.66% for S. aureus, which are much higher than pristine AEM (6.28% and 9.07%), respectively. In addition, the modified membrane has good operational stability during ED process and recovery ability after contamination, and also maintains satisfactory electrochemical properties. This investigation highlights a design of simple strategy for the preparation of antimicrobial and antifouling AEM, which can be used for ED.
