development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

Sulfidation of silver nanoparticles: natural antidote to their toxicity.

Nanomaterials are highly dynamic in biological and environmental media. A critical need for advancing environmental health and safety research for nanomaterials is to identify physical and chemical transformations that affect the nanomaterial properties and their toxicity. Silver nanoparticles, one of the most toxic and well-studied nanomaterials, readily react with sulfide to form Ag(0)/Ag2S c...

Sulfidation of silver nanoparticles decreases Escherichia coli growth inhibition.

Sulfidation of metallic nanoparticles such as silver nanoparticles (AgNPs) released to the environment may be an important detoxification mechanism. Two types of AgNPs-an engineered polydisperse and aggregated AgNP powder, and a laboratory-synthesized, relatively monodisperse AgNP aqueous dispersion-were studied. The particles were sulfidized to varying degrees and characterized to determine th...

Comparison of Blood Pressure in Mature and Premature Neonates Using Direct and Indirect Methods of Measurement

The aim of this study was to evaluate the correspondence of blood pressure (BP) measured using the direct intra-arterial method and indirect oscillometric monitor method. Twenty-three newborns with radial arterial catheters inserted were enrolled in this study. The gestational age (GA) ranged from 25-40 weeks and birth weight (BW) ranged from 700-3,550 g. Direct BP was measured using radial art...
