Synthesis, Characterization, and Electrochemical Evaluation of Copper Sulfide Nanoparticles and Their Application for Non-Enzymatic Glucose Detection in Blood Samples.

Glutathione-capped copper sulfide (CuS) nanoparticles with two different average sizes were successfully achieved by using a simple reduction process that involves only changing the reaction temperature. Temperature-induced changes in the size of CuS nanoparticles resulted in particles with different optical, morphological, and electrochemical properties. The dependence of electrochemical sensing properties on the sizes of CuS nanoparticles was studied by using voltammetric and amperometric techniques.

Engineered Inorganic/Organic-Core/Shell Magnetic FexOy Nanoparticles with Oleic Acid and/or Oleylamine As Capping Agents.

Magnetic nanoparticles with tailored surface chemistry are widely used for a number of different in vivo applications, ranging from tissue repair and magnetic cell separation through to cancer-hyperthermia, drug delivery and magnetic resonance imaging contrast enhancement. A major requirement for all these biomedical applications is that these nanoparticles must have high magnetization values and sizes smaller than 100 nm with a narrow particle size distribution. Thus nanoparticles must have uniform physical and chemical properties.

Analysis of the interaction of surfactants oleic acid and oleylamine with iron oxide nanoparticles through molecular mechanics modeling.

The interface interactions between surfactants oleic acid and oleylamine and magnetic nanoparticles are studied via molecular mechanics and dynamics. Mixtures of these two surfactants are widely advocated in the chemical synthesis of nanoparticles. However, the exact dynamic mechanism remains unclear.
