Abstract: Polymer-inorganic particle blends are incorporated into structures generally involving interfaces with additional materials that can be used advantageously for forming desirable devices. In some embodiments, the structures are optical structures, and the interfaces are optical interfaces. The different materials at the interface can have differences in index-of-refraction to yield desired optical properties at the interface. In some embodiments, structures are formed with periodic variations in index-of-refraction. In particular, photonic crystals can be formed. Suitable methods can be used to form the desired structures.

Abstract: Compositions comprising purified gadolinium-exchanged carboxylate-alumoxane nanoparticles in an aqueous solution are provided for use as MRI contrast agents. Targeted imaging is provided by nanoparticles comprising surface-bound antibodies specific for biomolecules present in a patient.

Abstract: A method and system are provided whereby rights in graphic works such as digital photographs and the like may be registered, and potential infringements of those rights monitored. The method includes storing representations of the works in a computer database together with details of any licensed users of the work, obtaining comparison representations from the internet or other computer network, and comparing the two representations to determine whether a threshold of similarity has been met. If the representations are determined to be similar or identical, the identity of the user of the comparison representation is determined and compared with identity of licensed users. In the event that the user is unlicensed, appropriate action such as alerting the rights owner may be taken. The database may also be used for displaying a portfolio of a rights owner's works, or for granting licences to use registered works.

Abstract: The invention relates to microfluidic devices and methods that employ electromagnetic radiation to move a droplet of fluid on a fluid-transporting surface of a substrate. Typically, radiation of a particular wavelength is directed through a substantially transparent material, and the radiation imparts an optical trapping force to move the droplet. In addition, a means for reducing evaporative loss from the droplet may be provided.
