Grating formation by metal-nanoparticle-mediated coupling of light into waveguided modes
L. Eurenius, C. Hägglund, E. Olsson, B. Kasemo & D. Chakarov
Published online: 11 May 2008; | doi:10.1038/nphoton.2008.80
We report the experimental observation of one- and two-dimensional grating patterns formed in a disordered metal-nanoparticle layer by a single light pulse. The phenomenon is attributed to interference effects between the incident light and waveguided modes. Such self-patterning behaviour could be useful for the fabrication of complex nanostructures and advanced photonic devices.

Nanometric optical tweezers based on nanostructured substrates
A. N. Grigorenko, N. W. Roberts, M. R. Dickinson & Y. Zhang
Published online: 11 May 2008; | doi:10.1038/nphoton.2008.78
Optical tweezers are well known for being able to control and move microscopic objects with high precision using focused laser beams. Alexander Grigorenko and colleagues report three-dimensional tweezers based on coupled pairs of gold nanodots in standard tweezer set-ups, which offer improved trapping efficiencies and reduced trapping volumes. Their tweezers could pave the way to improved manipulation of fragile, tiny biological objects.

Until print versions of AOP papers are published, they should be cited in the style "Author(s) Nature Photonics advance online publication, day month year (doi:10.1038/nphotonXXXXX)". Once the print version (identical to the AOP) is published, it should be cited as follows: "Author(s) Nature Photonics volume, page (year); advance online publication, (doi:10.1038/nphotonXXXXX)".
