The current study aims to utilize the bacteria Paraclostridium benzoelyticum strain 5610 to synthesize bio‐genic silver nanoparticles (AgNPs). Biogenic AgNPs were thoroughly examined using various characterization techniques such as UV‐spectroscopy, XRD, FTIR, SEM, and EDX. Synthesis of AgNPs was confirmed by UV–vis analysis resulting in absorption peak at 448.31 nm wavelength. The SEM analysis indicated the morphological characteristics and size of AgNPs which was 25.29 nm. The face centered cubic (FCC) crystallographic structure was confirmed by XRD. Furthermore, FTIR study affirmed the capping of AgNPs by different compounds found in biomass of the Paraclostridium benzoelyticum strain 5610. Later, EDX was used to determine the elemental composition with respective concentration and distribution. Additionally, in the current study the antibacterial, anti‐inflammatory, antioxidant, anti‐aging, and anti‐cancer ability of AgNPs was assessed. The antibacterial activity of AgNPs was tested against four distinct sinusitis pathogens: Haemophilus in‐fluenza, Streptococcus pyogenes, Moraxella catarrhalis and Streptococcus pneumonia. AgNPs shows significant inhibition zone against Streptococcus pyogenes 16.64 ± 0.35 followed by 14.32 ± 071 for Moraxella catarrhalis. Similarly, the antioxidant potential was found maximum (68.37 ± 0.55%) at 400 μg/mL and decrease (5.48 ± 0.65%) at 25 μg/mL, hence the significant antioxidant ability was observed. Furthermore, anti‐inflammatory activity of AgNPs shows the strongest inhibitory action (42.68 ± 0.62%) for 15‐LOX with lowest inhibition activity for COX‐2 (13.16 ± 0.46%). AgNPs have been shown to exhibit significant inhibitory actions against the enzyme elastases AGEs (66.25 ± 0.49%), which are followed by AGEs of visperlysine (63.27 ± 0.69%). Furthermore, the AgNPs show high toxicity against HepG2 cell line which shows 53.543% reduction in the cell viability after 24 h of treatment. The anti‐inflammatory activity demonstrated a potent inhibitory effect of the bio‐inspired AgNPs. Overall, the biogenic AgNPs have the ability to be served for the treatments of anti‐aging and also due to their anti‐cancer, antioxidant abilities NPs may be a useful therapy choice for a variety of disorders including cancer, bacterial infections and other inflammatory diseases. Moreover, further studies are required in the future to evaluate their in vivo biomedical applications. Highlights Biogenic synthesis of AgNPs using Paraclostridium benzoelyticum Strain for the first time. FTIR analysis confirmed capping of potent biomolecules which are of great use in applied field especially Nanomedicines. Notable antimicrobial activity against sinusitis bacteria and cytotoxic potential of synthesized AgNPs on in vitro basis produce a new idea shifting us to treat cancerous cell lines.

“…The recent technological development can be considered a double-edged sword due to its negative impact on human health, especially the issue of environmental pollution and the spread of many chronic diseases such as autoimmune, metabolism, and cancer [1][2][3]. Unfortunately, some of these diseases are still difficult to treat by conventional pharmacotherapy that relies primarily on many factors such as solubility, molecular weight, and hydrogen bonds, all of which can impede the achievement of a therapeutic response.…”

Polymers and their composites have recently attracted attention in both pharmaceutical and biomedical applications. Polyethylene glycol (PEG) is a versatile polymer extensively used in medicine. Herein, three novel PEG-based polymers that are pseudopolyrotaxane (PEG/α-CD) (1), titania–nanocomposite (PEG/TiO2NPs) (2), and pseudopolyrotaxane–titania–nanocomposite (PEG/α-CD/TiO2NPs) (3), were synthesized and characterized. The chemical structure, surface morphology, and optical properties of the newly materials were examined by FT-IR, 1H-NMR, SEM, and UV–Vis., respectively. The prepared polymers were used as drug carriers of sulfaguanidine as PEG/α-CD/Drug (4), PEG/TiO2NPs/Drug (5), and PEG/α-CD/TiO2NPs/Drug (6). The influence of these drug-carrying formulations on the physical and chemical characteristics of sulfaguanidine including pharmacokinetic response, solubility, and tissue penetration was explored. Evaluation of the antibacterial and antibiofilm effect of sulfaguanidine was tested before and after loading onto the prepared polymers against some Gram-negative and positive bacteria (E. coli, Pseudomonas aeruginosa, and Staphylococcus aureus (MRSA)), as well. The results of this work turned out to be very promising as they confirmed that loading sulfaguanidine to the newly designed polymers not only showed superior antibacterial and antibiofilm efficacy compared to the pure drug, but also modified the properties of the sulfaguanidine drug itself.

ZnO/MWCNTs nanocomposite has significant potential in photocatalytic and environmental treatment. Unfortunately, its photocatalytic efficacy is not high enough due to its poor light absorbance and quick recombination of photo-generated carriers, which might be improved by incorporation with noble metal nanoparticles. Herein, Ag-doped ZnO/MWCNTs nanocomposite was prepared using a pulsed laser ablation approach in the liquid media and examined as a degradable catalyst for Rhodamine B. (RhB). Different techniques were used to confirm the formation of the nanostructured materials (ZnO and Ag) and the complete interaction between them and MWCNTs. X-ray diffraction pattern revealed the hexagonal wurtzite crystal structure of ZnO and Ag. Additionally, UV-visible absorption spectrum was used to study the change throughout the shift in the transition energies, which affected the photocatalytic degradation. Furthermore, the morphological investigation by a scanning electron microscope showed the successful embedding and decoration of ZnO and Ag on the outer surface of CNTs. Moreover, the oxidation state of the formed final nanocomposite was investigated via an X-ray photoelectron spectrometer. After that, the photocatalytic degradations of RhB were tested using the prepared catalysts. The results showed that utilizing Ag significantly impacted the photo degradation of RhB by lowering the charge carrier recombination, leading to 95% photocatalytic degradation after 12 min. The enhanced photocatalytic performance of the produced nanocomposite was attributed to the role of the Ag dopant in generating more active oxygen species. Moreover, the impacts of the catalyst amount, pH level, and contact time were discussed.
