Researchers from Institute of Chemistry Report Details of New Studies and Findings in the Area of Nanorods

February 18, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Nanorods have been published. According to news originating from Beijing, People's Republic of China, by NewsRx correspondents, research stated, "Accurate determination of copper in complex biological media such as cells is quite difficult, and an analytical strategy based on copper-modulated formation of core-shell gold nanorods is described. Selective and label-free sensing can be achieved by measuring the change in the localized surface plasmon resonance absorption."

Our news journalists obtained a quote from the research from the Institute of Chemistry, "The technique can determine trace amounts of copper in human serum, urine, and red blood cells without or with minimal sample pretreatment. The Cu detection limits are 20.67 mu M in human serum, 0.193 mu M in human urine, and 3.09 X 10(-16) g in a single cell. The advantages of the technique are the high selectivity, simple or no sample pretreatment, and label free."

According to the news editors, the research concluded: "Boasting a practical detection limit down to 2 IM, only 10(3) red blood cells are needed to conduct the analysis and the technique may be extended to the detection of trace amounts of copper in a single cell."
