Abstract:
The present invention provides visible light sensitive and ultraviolet (UV) light sensitive composition for DNA transfer comprising acid sensitive polyacetals developed as DNA/RNA delivery agents, a photoacid generator and optionally a photosensitizer.
Abstract:
We have designed, built and operated an innovative JTOC system utilizing a holographic photopolymer as the square law detector to record the holographic data for one-step correlation signal requisition in real time. The resultant high-resolution, high- speed JTOC is useful to perform real-time pattern recognition. An example application that has been demonstrated is fingerprint verification.
Abstract:
The present invention provides compounds and compositions, which include: at least one chromophore having strong simultaneous two-photon or multi-photon absorptivity; at least one acid- or radical-generator in close proximity to the chromophore; such that the single- or multi-photon excitation of the chromophore results in the generation of an acid and/or redical that is capable of activating chemistry; and such that compositions of matter based on the componds and compositions of the invention can be photo-patterned by one- or multiphoton excitation.

Abstract:
Light-emitting chromophores (lumophores) that emit different colored light may be covalently attached to a nanoparticle core such as a silsequioxane. The light emission profile of the resulting lumophore-functionalized nanoparticle is the sum of the light emission of all of the lumophores attached to the nanoparticle. In some embodiments, the lumophore-functionalized nanoparticle is white light-emitting.

Abstract:
Methods for significantly improving the working lifetime of photorefractive materials and photorefractive articles involve annealing the photorefractive materials at a temperature higher than the temperature range in which degradation occurs. The methods are particularly applicable to amorphous photorefractive materials and devices in which phase separation results in performance degradation or device failure.
