Antimicrobial resistance is an ever-growing global concern to public health with no clear or immediate solution. Silver nanoparticles (AgNPs) have long been proposed as efficient agents fight the growing number of antibiotic-resistant strains. However, synthesis these particles often linked high costs and use toxic, hazardous chemicals, environmental impact. In this study, we successfully produced AgNPs by green aid extract two brown algae-Cystoseira baccata (CB) Cystoseira tamariscifolia...
The integral utilization of sustainable resources with versatile, efficient and cleaner processes is encouraged. Hydrothermal treatment subcritical water a chemical free, tunable rapid technology providing enhanced yield compared to conventional extraction was explored for the benign by design depolymerization carrageenan from Chondrus crispus. Up 90% seaweed solubilized operating under nonisothermal regime during heating up 200 °C 75.5% crude attained at 140 °C. Crude could not be...
The biocompatibility properties of gold and silver nanoparticles synthesized by green chemistry.
Bacterial and fungal infections are a challenging global problem due to the reported increasing resistance of pathogenic microorganisms conventional antimicrobials. Nanomaterials promising strategy fight caused by multidrug-resistant microbes. In this work, gold (Au@UP) silver (Ag@UP) nanoparticles were produced for first time green synthesis using an aqueous extract invasive macroalgae Undaria pinnatifida (UP). The characterized wide range physicochemical techniques. Au@UP Ag@UP...
Over the last years, there has been an increasing trend towards use of environmentally friendly processes to synthesize nanomaterials. In case nanomedicine, bionanofactories with associated biological properties, such as seaweed, emerged a promising field work due possibility they open for both preservation those properties in nanomaterials synthesized and/or reduction their toxicity. present study, gold ([email protected]) and silver nanoparticles were using aqueous extract Saccorhiza...
Research on gold nanoparticles (AuNPs) occupies a prominent place in the field of biomedicine nowadays, being their putative toxicity and bioactivity areas major concern. The green synthesis metallic using extracts from marine organisms allows avoidance hazardous production steps while maintaining features interest, thus enabling exploitation promising bioactivity.To synthesize characterize AuNPs using, for first time, macroalga Cystoseira tamariscifolia aqueous extract (Au@CT).Algal were...
This study reports on the green and cost-efficient synthesis of gold nanoparticles from three different red algae extracts. The synthesized were fully characterized by UV-Vis spectroscopy, HRTEM, Z-potential. Relevant components occurring in extracts, such as polysaccharides or phenolic content, assessed analytical techniques spectrophotometric assays liquid chromatography. Finally, antioxidant, antitumoral, anti-inflammatory potential both extracts analyzed order to determine a possible...
The significance of gold nanoparticles in nanobiotechnology and the trend towards development green methods synthesis has boosted research on use new natural resources, such as plants, reducing agents for formation nanoparticles. This article focuses Hypericum perforatum L., a plant known since ancient times its multiple applications treatment variety diseases. In this study, flowers, leaves, stems were separated their corresponding ethanolic extracts (HPF, HPL, HPS) extensively...
