Raman systems include a radiation source, a radiation detector, and a Raman device or signal-enhancing structure. Raman devices include a tunable resonant cavity and a Raman signal-enhancing structure coupled to the cavity. The cavity includes a first reflective member, a second reflective member, and an electro-optic material disposed between the reflective members.

A multi-tiered network for gathering detected condition information includes a first tier having first tier nodes and a second tier having a second tier node. The second tier node is operable to receive detected condition information from at least one of the first tier nodes in a substantially autonomous manner. In addition, the second tier node is operable to at least one of store, process, and transmit the detected condition information. The network also includes a third tier having a third tier node configured to receive the detected condition information and to at least one of store and process the detected condition information.

Abstract:
The present invention provides a method of forming a controlled distribution of nano-particles on a surface. The method includes forming a layer of block copolymer having at least two types of blocks. Each type of block has a respective type of polymer. The block copolymer has an exposed surface and the blocks have exposed surface portions. The blocks are distributed on a substrate. The method also includes attaching nano-particles to the surface portions of at least one and less than all types of the blocks so that the attached particles form a controlled distribution on the surface of the block copolymer.
