“…The diameter and interactions of the AgNPs are two advantageous factors in designing modified AgNPs with improved mercury detection and removal capability [ 36 ]. Carboxylic acid-capped AgNPs show better antimicrobial properties even against drug-resistant strains [ 37 , 38 , 39 , 40 ]. As-synthesized silver nanoparticles either capped with hydrophilic ligands or carboxylic acids have also been reported to detect Hg+ at ppm levels [ 33 , 41 ].…”

The present work reports the synthesis, characterization, and antimicrobial activities of adipic acid-capped silver nanoparticles (AgNPs@AA) and their utilization for selective detection of Hg2+ ions in an aqueous solution. The AgNPs were synthesized by the reduction of Ag+ ions with NaBH4 followed by capping with adipic acid. Characterization of as-synthesized AgNPs@AA was carried out by different techniques, including UV–Visible spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Dynamic Light Scattering (DLS), and zeta potential (ZP). In the UV–Vis absorption spectrum, the characteristic absorption band for AgNPs was observed at 404 nm. The hydrodynamic size of as-synthesized AgNPs was found to be 30 ± 5.0 nm. ZP values (−35.5 ± 2.4 mV) showed that NPs possessed a negative charge due to carboxylate ions and were electrostatically stabilized. The AgNPs show potential antimicrobial activity against clinically isolated pathogens. These AgNPs were found to be selectively interacting with Hg2+ in an aqueous solution at various concentrations. A calibration curve was constructed by plotting concentration as abscissa and absorbance ratio (AControl − AHg/AControl) as ordinate. The linear range and limit of detection (LOD) of Hg2+ were 0.6–1.6 μM and 0.12 μM, respectively. A rapid response time of 4 min was found for the detection of Hg2+ by the nano-probe. The effect of pH and temperature on the detection of Hg2+ was also investigated. The nano-probe was successfully applied for the detection of Hg2+ from tap and river water

“…Additionally, nanomaterials’ distinct dimensions and physical characteristics enable them to target biofilms and treat resistant illnesses [ 103 ]. Ag nanoparticles (AgNPs) have a large surface area and small size, and they are one of the most effective antimicrobials [ 104 ]. This encourages contact between them and their targets, such as bacterial cells [ 105 ].…”

Recent Advances in Nanotechnology for the Management of Klebsiella pneumoniae–Related Infections

Klebsiella pneumoniae is an important human pathogen that causes diseases such as urinary tract infections, pneumonia, bloodstream infections, bacteremia, and sepsis. The rise of multidrug-resistant strains has severely limited the available treatments for K. pneumoniae infections. On the other hand, K. pneumoniae activity (and related infections) urgently requires improved management strategies. A growing number of medical applications are using nanotechnology, which uses materials with atomic or molecular dimensions, to diagnose, eliminate, or reduce the activity of different infections. In this review, we start with the traditional treatment and detection method for K. pneumoniae and then concentrate on selected studies (2015–2022) that investigated the application of nanoparticles separately and in combination with other techniques against K. pneumoniae.

“…Green synthesis methods [32] are among the ideal methods applied for the production of nanoparticles because they are harmless [33], cheap [34], and simple [35, 36]. One of the significant nanotechnological research focuses on synthesizing M/MO NPs such as silver [37, 38], carbon [39, 40], zinc oxide [41–43], gold [44–46], copper [47–49], nickel [50–52], selenide [53], palladium [54, 55], molybdenum [56, 57], tin oxide [58], titanium [59], and iron [60, 61]. The M/MO NPs have a broad range of applications [62, 63] such antifungal [64–66], cytotoxicity [67, 68], antioxidant [69–71], photocatalyst [72–74], antibacterial [75–77], biosensor [78–80], extraction [81, 82], agriculture [30, 83], food analysis [84], energy [85–87], detection [88–90], and drug delivery [91–93].…”

Here, the authors described a sustainable green synthesis approach to synthesize cuprous oxide nanoparticles (NPs) using Olea europaea extract. The resulting synthesized cuprous oxide NPs were characterized by the UV–Visible spectra, scanning electron microscopy (SEM)/energy‐dispersive X‐ray spectroscopy (EDS), transmission electron microscopy (TEM), and X‐ray diffraction (XRD). The average cuprous oxide NPs crystallite size of about 30 nm was calculated using the Scherrer formula. According to TEM, the resulting synthesized cuprous oxide NPs are spherical shaped. The cuprous oxide NP provides good antibacterial activity versus the two strains compared to Olea europaea aqueous extract; cuprous oxide NP has higher MIC against Staphylococcus aureus and Klebsiella pneumoniae.
