Synthesis and Characterization of Silver and Gold Nano-Structures on Chitosan-Porous Anodic Alumina Nano-Composite
This study was designed to probe the fabrication of unique silver and gold nano-structures engaging a self-designed chitosan-porous anodic alumina nano-composite as a template. Porous anodic alumina has been manufactured by di-step aluminum anodization in an oxalic acid electrolytic bath. The surface properties of porous anodic alumina were reinforced by chitosan neutralized in sodium hydro...
متن کاملextraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds
سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...
Biosynthesis, Characterization, Comparative and Synergistic Activity of Silver Nano Particles from Bacillus Species against Human Pathogens
Nanotechnology is useful in diagnostic techniques, drug delivery, sunscreens, antimicrobial bandage, and disinfectants. In the present investigate work synthesis of silver nanoparticles was prepared by biological method by reducing silver nitrate using the bacteria Bacillus species. The construction of nanoparticles was established by UV-visible spectroscopy with a maximum absorbance at 434nm, ...
متن کاملAntimicrobial activity of silver nitrate against periodontal pathogens.
Metal ions were evaluated as potential antimicrobial agents suitable for local delivery in the oral cavity for the treatment of periodontitis. Silver nitrate, copper chloride, and zinc chloride were tested for antimicrobial activity in in vitro killing assays conducted in phosphate buffered saline with a series of oral bacteria including gram-negative periodontal pathogens and gram-positive str...
متن کاملantimicrobial effect of nano-zinc oxide and nano-chitosan particles in dental composite used in orthodontics
background : incidence of white spots due to demineralization of enamel and gingival problems is an unacceptable result of orthodontic treatment. plaque accumulation and bacterial biofilm growth are responsible for these phenomena. the resin-based dental composites used as bonding agents in orthodontics play a major role in mentioned problems. as recent researches assert the an...
