Gold nanoparticles have attracted much interest as a platform for development of multifunctional imaging and therapeutic agents. Multifunctionalized gold nanoparticles are generally constructed by covalent assembly of a gold core with thiolated ligands. In this study, we have assembled multifunctionalized gold nanoparticles in one step by nucleic acid hybridization of ODN (oligodeoxynucleotide)...

OWEN, CHARLES A., JR., and JANE B. HAZELRIG. Copper deJi&nc~ and copper toxicify in the rat. Am. J, Physiol. 215(Z) : 334-338. I968.-Changes in metabolism of an intravexmusly injected tracer dose of 64Cu were measured in Sprague-Dawley rats subjected to copper loading, by addition of cupric acetate to the drinking water, or made copper deficient, by use of a milk-powder diet and copper-free wat...

Isotopic techniques have become a valuable tool for assessing the lability or potential availability of elements in soil. Until now, work on soil Cu has been limited to E-value methods where soil solution extracts are obtained by physical means due to the very short (12.4 h) half-life of the radio isotope 64Cu. However, a stable isotope method has recently been developed for determining soil Cu...
