Abstract Chitosan is one of the most abundant biopolymers in nature with high economic value due to its biocompatibility, biodegradability, lack toxicity, and antifungal activity. In this study, chitosan was extracted from three different sources: Blaps lethifera (CSB), Pimelia fernandezlopezi (CSP), Musca domestica (CSM). The ash content (AC), moisture (MC), fat binding capacity (FBC), water (WBC), deacetylation degree (DD) were determined for prepared chitosans. effect DD on antibacterial...
Chitosan was used in the sol-gel synthesis of zinc oxide nanoparticles (ZnO NPs) as a capping agent order to control size, morphology, optical bandgap, photocatalytic efficiency, and antimicrobial activity. Different chitosan sources were for ZnO NPs, namely shrimp shells, crab Streptomyces griseus bacteria. The efficiency studied by using methylene blue (MB) photodegradation test, antibacterial activity different types NPs investigated agar well diffusion technique. particle size varied...
Ephedra alata leaf extracts have therapeutic properties and contain various natural compounds known as phytochemicals. This study assessed the phytochemical content antioxidant effects of a extract, well zinc oxide (ZnO) nanoparticle production. The extract contained phenolic acids, including vanillic acid, chlorogenic gallic p-coumaric vanillin rutin. Its total flavonoid were 48.7 ± 0.9 mg.g -1 1.7 0.4 , respectively. displayed DPPH inhibition rate 70.5%, activity 49.5 3.4 significant...
Insects are a readily available source of chitosan due to their high reproductive rates, ease breeding, and resistance changes in ecosystem. This study aimed extract from several widespread insects: Blaps lethifera (CS-BL), Pimelia fernandezlopezi (CS-PF), Musca domestica (CS-MD). The was also extended using the obtained chitosans removing methylene blue dye (MB) wastewater. chitosan, initial concentration MB dye, reaction time were chosen as working parameters. experiments designed central...
Dear Editor,Highlights Skin is composed of several layers essential to its response and function injury. Wound healing process achieve a quick effective skin tissue regeneration. Biopolymers, such as chitosan, have been widely utilized in regenerative medicine. Nanomaterial topical use has shown dramatically enhance healing. injury: hypodermis, dermis, epidermis. Damaged spontaneously starts the wound when injured1. Inflammation, hemostasis, remodeling, proliferation (or scar development)...
The green approach-based nanoparticle synthesis is considered a more cost-effective and ecologically responsible method of producing nanoparticles than other standard techniques. A major accomplishment in resolving these issues the use for environmental pollution remediation. This article describes simple MgO ZnO (NPs) using aqueous extracts Zingiber officinale Glycyrrhiza roots as stabilizing reducing agents, respectively. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction...
Metal and metal oxide nanoparticles are gaining traction in inorganic catalysis photocatalysis, driving the development of eco-friendly methods. This study introduces an cost-effective approach for synthesizing Al2O3 (NPs) using extracts derived from leaves Calligonum comosum L. The primary objective this investigation is to assess photocatalytic efficacy synthesized catalyst addressing organic pollutants. NPs exhibit a spherical morphology with crystalline arrangements, as evidenced by...

Background Chicken eggshells, a common poultry byproduct, are rich in calcium and provide sustainable source for producing oxide nanoparticles (CaO NPs). Their use eco-friendly synthesis aligns with the growing emphasis on materials environmental biomedical applications. Objectives: This study develops an method synthesizing CaO NPs from chicken characterizes their physicochemical properties, evaluates antibacterial antifungal activities. It also tests effectiveness removing heavy metal ions...
The Oued Zénati, a vital waterway in Algeria, faces severe pollution from urban discharges, hospital wastewater, and agricultural activities, threatening both the ecosystem public health. This is characterized by high nutrient levels, suspended solids, fecal contamination indicators, jeopardizing biodiversity human well-being. To explore natural restoration solutions, this study assessed purification potential of reeds (Phragmites australis) found Zénati riverbed. Water quality was analyzed...
