Abstract α-amylase was immobilized covalently on iron oxide magnetic nanoparticles. The synthesis of magnetic nanoparticles was done by the coprecipitation conventional method. The chemical composition and particle size of the synthesized particles was confirmed via X-ray diffraction. Tyrosine‚ Lucien and chitosan and glutaraldehyde were investigated to make a covalent binding between the iron oxide magnetic core and the immobilized enzyme. Immobilization using chitosan and glutaraldehyde show

1- Synthesis of silver nanoparticles by Bacillus sp.: The microorganisms in the most contaminated toilet Sink were isolated by dilution technique. The dominant bacterial strains are identified as Bacillus sp.‚ on the basis of morphological and biochemical characteristics. Gram’s staining: Gram positive and rod shape. They were serially diluted and spread on nutrient agar plates. The starch has been hydrolyzed and a clear zone by the addition of iodine solution. Visual identification: When bacterial

ABSTRACT: Silver nanoparticles are nanoparticles of silver which are in the range of 1 and 100 nm in size. Silver nanoparticles have unique properties which help in molecular diagnostics‚ in therapies‚ as well as in devices that are used in several medical procedures. The major methods used for silver nanoparticle synthesis are the physical and chemical methods. The problem with the chemical and physical methods is that the synthesis is expensive and can also have toxic substances absorbed onto
