Abstract:

A method and apparatus are disclosed for forming an optical trap with light directed through or above a semiconductor material. A preferred embodiment selected light-trapping wavelengths that have lower absorption by the semiconductor. A preferred embodiment provides for an optical trapping through semiconductor employing a thin silicon (Si) wafer as a substrate. Further embodiments of the invention provide for microchannel fabrication, force probe measurement, sorting, switching and other active manipulation and assembly using an optical trap.

Abstract:

The present invention is a laminate and resultant package expressing an aroma burst. The laminate or package is comprised of a polyolefin sealing layer; a pressure sensitive adhesive layer and microcapsules containing an active core material, the microcapsules dispersed in a resealably tacky pressure sensitive adhesive layer; the pressure sensitive adhesive sandwiched between at least two layers by being disposed along substantially an entire surface of the polyolefin sealing layer and in continuous and direct contact with a second polyolefin layer opposing and coextensive with the polyolefin sealing layer; and the microcapsules in the pressure sensitive adhesive layer having less tensile strength than the adhesive such that a fraction of the microcapsules rupture releasing core material such as an aroma or fragrance when the pressure sensitive adhesive layer is separated when the polyethylene and first polyolefin layers sandwiching the pressure sensitive adhesive are pulled apart. The laminate polyolefin sealing layer can have a portion such as one or more edge areas that are sealed to itself or a second laminate forming a lumen or chamber area. The lumen area is physically isolated from the pressure sensitive adhesive and microcapsule layer by a polyolefin layer until the polyolefin layer is ruptured.
