Researchers directly deposit gold nanoparticles in suspension

The delivery, manipulation and assembly of functional materials such as metal nanoparticles into predefined architectures and patterns is of great interest in nanotechnology. Nanoscale patterns of nanoparticles have the potential to be used in miniature electronic circuits or in plasmon waveguides to guide the transport of electromagnetic energy below the diffraction limit. Nanoparticles functionalized with biological materials can also be placed between electrodes for use in biosensing applications.
