Growth of gold tips onto hyperbranched CdTe nanostructures

Uniformly sized gold nanoparticles are selectively deposited onto the tips of hyperbranched CdTe nanostructures, as illustrated in the figure. The reaction mechanism is thought to involve the reduction of gold by the CdTe nanostructures. These novel hybrid semiconductor-metal nanostructures may be useful for energy conversion, optoelectronics, and biofunctional platforms.
