Abstract: The present invention relates to artificial tear compositions and ophthalmic compositions suitable for drug delivery. In one embodiment of the present invention, the compositions comprise a galactomannan polymer such as guar or hydroxypropyl guar, hyaluronic acid, and a cis-diol such as sorbitol. In a preferred embodiment, the compositions also comprise a borate compound.

Abstract: Protein-based photovoltaic cells and the manufacture and use of protein-based photovoltaic cells are described. In one embodiment, bacteriorhodopsin from Halobacterium salinarum, which undergoes structural transitions when irradiated with a given wavelength of light, is used as the protein in the protein-based photovoltaic cells. In another embodiment, mutant bacteriorhodopsin from H. salinarum is used. Exposure of the protein to sunlight causes proton transfer across a membrane resulting in the generation of an electrical charge. The protein can be oriented and/or layered on a substrate and modified by mutation to enhance transmembrane proton transfer, covalent binding to a substrate and layering. The protein-based photovoltaic cells sequentially or simultaneously generate hydrogen gas from water or salt, which also can be harnessed to produce electricity.

Abstract: Bacteriorhodopsin protein variants and methods using the bacteriorhodopsin variants for performance in holographic and three-dimensional (3D) memory storage devices are described. The amino acid and chemical modifications of bacteriorhodopsin provided herein achieve greatly enhanced protein performance. The memory storage devices write, read and erase data proficiently. The bacteriorhodopsin protein variants are useful in optical memory storage and associative processor systems. Irradiation of the light-sensitive protein with light of known wavelength causes the protein to switch between different states. The variants enter the branched photocycle via a single or a two photon process and form the permanent ‘Q’ state more efficiently than the wild-type bacteriorhodopsin protein. This branching photocycle of the variants is exploited in the fabrication of 3D memory storage devices.
