Understanding the mechanism of surface-enhanced Raman scattering (SERS) of molecules on semiconductor nanostructures is directly related to our capabilities of designing and optimizing new SERS-active substrates for broad applications in the field of molecular detection and characterization. Here, we present an exploration of using cuprous oxide nanostructures with hierarchical porosity for enh...

In the present communication we report the fabrication a unique core-shell inorganic nanomaterial with potential therapeutic and diagnostic functions. It contains an iron-cobalt (FeCo) core that demonstrates MRI contrast property and a thin nanoshell of gold that inhibits the function of a pro-angiogenic growth factor, VEGF165. Au(FeCo) core-shell nanomaterials are fabricated in the gas phase a...

The spectroscopic characterization of individual nanostructures is of fundamental importance to understanding a broad range of physical and chemical processes. One general and powerful technique that addresses this aim is dark-field microscopy, with which the scattered light from an individual structure can be analyzed with minimal background noise. We present the spectroscopic analysis of indi...
