Abstract: A new physical scheme is presented for the detection of copper, based on the use of a fluorescently labeled dendrimer anchored on a gold nanowire. Upon light illumination surface plasmon resonance was generated from the gold nanowire, which promoted quenching of the dendrimer fluorescence as a result of the energy transfer between the dendrimer and the copper ions. The monotonic dependence of the fluorescence quenching on copper concentration was exploited to reach a copper detection sensitivity of 2 nM. In addition, the fluorescence of the labeled dendrimers was quenched specifically by copper in a matrix of common metal ions. Using simulations we calculated the enhanced optical near field for a dendrimer-coated gold nanowire illuminated by a TM-polarized plane wave, which provided a physical basis for the sensitive copper detection using the current experimental scheme.

Abstract: The physical interaction between a lipid vesicle and a silver nanoparticle (AgNP)-human serum albumin (HSA) protein “corona” has been examined. Specifically, the binding of AgNPs and HSA was analyzed by spectrophotometry, and the induced conformational changes of the HSA were inferred from circular dichroism spectroscopy. The fluidity of the vesicle, a model system for mimicking cell membrane, was found to increase with the increased exposure to AgNP-HSA corona, though less pronounced compared to that induced by AgNPs alone. This study offers additional information for understanding the role of physical forces in nanoparticle-cell interaction and has implications for nanomedicine and nanotoxicology.
