Abstract

In the present communication, we report the fabrication of a unique core-shell inorganic nanomaterial with potential therapeutic and diagnostic functions. It contains an iron-cobalt (FeCo) core that demonstrates magnetic resonance imaging (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 and characterized using transmission electron microscopy, energy dispersive spectrum, inductively coupled plasma analysis, and MRI. Inhibition of VEGF165 function by Au(FeCo) is demonstrated against VEGF165/VPF-induced signaling cascades and proliferation of human umbilical vein endothelial cells (HUVECs). The self-contrast property of Au (FeCo) is determined in vitro by MRI after incubating HUVECs with Au(FeCo), demonstrating intrinsic contrast property of this potentially therapeutic nanomaterial. In brief, we report here the successful fabrication of an inorganic core-shell nanomaterial with potential therapeutic and diagnostic functions. It inhibits the function of VEGF165 and functions as a MRI contrast agent.
