Controlled deposition of metal nanostructures on various substrates is highly desirable for electronics, photonics, sensing and catalysis. A laser focused beam has been used to deposit metal nanoparticles and nanostructures based on optical forces with diffraction-limited spatial resolution. We demonstrate fabrication of nanostructured silver wires, spots and wire arrays by using a confocal microscope setup, offering highly reproducible nanostructured silver growth and pattern writing. Particularly, laser-deposited silver micro-wires show adjustable electronic conductivities. Taking into accounts the superior spatial resolution and versatile pattern design, this technique is promising for a variety of applications such as microelectronics and bio-chips.
