In the present work, bioaugmented zinc oxide nanoparticles (ZnO-NPs) were prepared from aqueous fruit extracts of Myristica fragrans. The ZnO-NPs characterized by different techniques such as X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, ultraviolet (UV) scanning electron microscopy (SEM), transmission (TEM), dynamic light scattering (DLS), and thermogravimetric analysis (TGA). crystallites exhibited a mean size 41.23 nm measured via XRD highly pure, while SEM TEM analyses synthesized NPs confirmed their spherical or elliptical shape. functional groups responsible for stabilizing capping using FTIR analysis. ζ-size ζ-potential reported 66 −22.1 mV, respectively, DLS technique can be considered moderate stable colloidal solution. Synthesized used to evaluate possible antibacterial, antidiabetic, antioxidant, antiparasitic, larvicidal properties. found active against bacterial strains both coated with antibiotics alone. Klebsiella pneumoniae was most sensitive strain (27 ± 1.73) imipinem (26 1.5). displayed outstanding inhibitory potential enzymes protein kinase (12.23 0.42), α-amylase (73.23 α-glucosidase (65.21 0.49). Overall, have shown significant activity (77.3 1.8) Aedes aegypti, mosquitoes involved in dengue fever. Similarly, tremendous leishmanicidal also observed promastigote (71.50 0.70) amastigote (61.41 0.71) forms parasite. biosynthesized excellent antioxidant biocompatible nanomaterials. Biosynthesized photocatalytic agents, resulting 88% degradation methylene blue dye 140 min.

Abstract Bacterial wound infection is one of the most common nosocomial infections. The unnecessary employment antibiotics led to raising growth antibiotic‐resistant bacteria. Accordingly, alternative armaments capable accelerating healing along with bactericidal effects are urgently needed. Considering this, we fabricated chitosan (CS)/polyethylene oxide (PEO) nanofibers armed antibacterial silver and zinc nanoparticles. nanocomposites exhibited a high antioxidant effect activity against Staphylococcus aureus , Escherichia coli Pseudomonas aeruginosa . Besides, based on results cell viability assays, optimum concentration ZnONPs AgNPs in nanofibrous mats 0.2% w/v 0.08% respectively had no cytotoxicity fibroblast cells. scaffold also showed good blood compatibility according coagulation time. As well as significant migration proliferation margin, wound‐healing assay. All all, developed biocompatible, antioxidant, Ag‐ZnO NPs incorporated CS/PEO their potential an effective dressing.

Increased request for metal and oxide nanoparticles has led to their large-scale production using high-energy methods with various toxic solvents. This cause environmental contamination, thus eco-friendly "green" synthesis become necessary. An alternative way synthesize includes bioresources, such as plants plant products, bacteria, fungi, yeast, algae, etc. "Green" low toxicity, is safe human health environment compared other methods, meaning it the best approach obtaining nanoparticles. review reveals 12 principles of chemistry examples biological components suitable synthesis, well modern scientific research magnetic Particularly, extracts green tea, fruits, roots, leaves, etc., obtain Fe3O4 NPs. The precursors egg white (albumen), leaf fruit extracts, can be used spinel are being widely antimicrobials, photocatalysts adsorbents. demonstrate toxicity high biocompatibility, which allows biomedical application, especially targeted drug delivery, contrast imaging hyperthermia applications. silver, gold, platinum palladium from red been described.

Brain tumors, especially glioblastoma, remain the most aggressive form of all cancers because inefficient diagnosis and profiling. Nanostructures, such as metallic nanostructures, silica nano-vehicles, quantum dots, lipid nanoparticles (NPs) polymeric NPs, with high specificity have made it possible to permeate blood–brain barrier (BBB). NPs possess optical, magnetic photodynamic properties that can be exploited by surface modification, bio composition, contrast agents’ encapsulation coating tumor-derived cells. Hence, nanotechnology has brought on a revolution in field imaging brain tumors cancers. Recently, nanomaterials biomimetic functions been introduced efficiently cross BBB engulfed deep skin cancer malignancies for imaging. The review focuses nanotechnology-based diagnostic approaches exploration Moreover, also summarizes few strategies image glioblastoma multimodal functional nanocomposites more precise accurate clinical diagnosis. Their unique physicochemical attributes, including nanoscale sizes, larger area, explicit structural features ability encapsulate diverse molecules their surface, render nanostructured materials excellent nano-vehicles convey drug target region. This sheds light current progress various kinds nanomaterials, liposomes, nano-micelles, dendrimers, carbon nanotubes, dots (gold, silver zinc oxide NPs), efficient delivery treatment cancer.
