Abstract: An apparatus and method are provided for converting light into a surface plasmon polariton on a plasmon supporting nanostructure and then controlling the emission of the re-emitting light. A circuit component is also described that is constructed of a nanostructure, which is comprised of at least one plasmon supporting metal. The metal can propagate the light, as a surface plasmon polariton, through the one-dimensional nanostructure and re-emit the light. The metal is a plasmon supporting metal, for example but not limited to, gold, silver, copper, and aluminum.

Abstract: Photochromic fluorescent protein moiety having two or more stable states having excitation or emission spectra that are shifted from one wavelength region to another wavelength region in the two states are described. The photochromic material switches between states by irradiation with light of appropriate wavelengths. The two states are preferably stable at room temperature and in the dark. The switching between states can be reversible.

Abstract: A magnetic chuck assembly comprises top and bottom plates separated by a layer of non-magnetizable material, each plate having magnetizable sections separated by strips of non-magnetic material. A rotor mounted between the top and bottom plates carries a plurality of permanent magnets substantially symmetrically disposed therein. The magnets in each half of the rotor are of the same polarity but those in one half are of opposite polarity to those in the other. When the rotor is turned to a position in which all the magnets of like polarity in one half thereof lie between the magnetizable sections of the plates on the same side of the non-magnetizable strips, the sections become magnetized and hold a magnetizable workpiece in place on the edges of the plate. Switching the rotor to a position in which equal numbers of magnets of opposite polarity lie between the magnetizable sections serves to de-energize the latter and release the workpiece.
