silver nanoparticles were synthesized by biophysical method. Silver nanoparticles were characterized using UV-Visible absorption spectroscopy (Surface Plasmon absorption at 418-420 nm)‚ Energy Dispersive Spectroscopy (EDX)‚ Scanning Electron Microscopy (SEM) and X- ray diffraction (XRD). The cytotoxic effect of silver nanoparticles on acute myeloid leukemia cell line (THP – 1 cell line) was studied in vitro. The activity of chemotherapeutic drugs Cyclophosphamide and Busulfan was enhanced in

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

they are transparent and almost colorless when suspended in an aqueous medium. To study their properties and divide microorganisms into specific groups for diagnostic purposes‚ biological stains and staining procedures‚ in conjunction with light microscopy‚ have become major tools in microbiology. Chemically‚ a stain may be defined as an organic compound containing a benzene ring plus a chromophore and an auxochrome. Stains are of 2 types: 1. Acidic stains e.g.‚ picric acid 2. Basic stains e.g.‚ methylene
