Abstract: A novel Claisen rearrangement reaction is provided. An allylic reactant such as an allylic amine, an allylic ether or an allylic thioether is reacted with an acid chloride in the presence of a Lewis acid catalyst composition composed of a Lewis acid and a base selected from the group consisting of tertiary amines and non-nitrogenous bases. The stereochemistry of the reaction product is readily controlled by the positioning and size of substituents on the allylic reactant. The reaction may be carried out on a solid support, i.e., on the surface of a substrate suitable for conducting solid phase chemical reactions.

Abstract: The present invention provides a means to substantially decrease the pH bias that is commonly observed with pH data obtained using ion selective electrode (ISE) containing instruments that have a solvent polymeric membrane based ISE pH electrode. The pH bias is reduced by utilizing the discovery that the presence of protein in a liquid sample induces an apparent interference with the pH value.

Abstract: A microdevice having interior cavity with high aspect ratio features and ultrasmooth surfaces, and associated method of manufacture and use is described. An LIGA-produced shaped bit is used to contour polish the surface of a sacrificial mandrel. The contoured sacrificial mandrel is subsequently coated with a structural material and the mandrel removed to produce microdevices having micrometer-sized surface features and sub-micrometer RMS surface roughness.

Abstract: A method for producing a multi-domain alignment layer, as well as multi-domain alignment layers produced thereby and liquid crystal displays comprising the same, are provided. In the subject method, an alignment layer is produced on an alignment surface by directing an ion beam or ion beams at the surface at an angle not equal to 90°, so that the ions contact the surface at non-normal incidence. The substrate may be rotated or the ion beam(s) re-directed or the ion beam source moved so that the surface may be bombarded from different directions in different regions resulting in multiple alignment layer domains with differing alignment. In an alternative embodiment, two ion beams with different angles of incidence may be directed at the surface simultaneously or sequentially, thereby creating multiple alignment layer domains without need for rotation of the substrate. The resultant multi-domain alignment layers find use in liquid crystal display devices.

Abstract: Methods and compositions for transporting drugs and macromolecules across biological membranes are disclosed. In one embodiment, the invention includes a method for enhancing transport of a selected compound across a biological membrane, wherein a biological membrane is contacted with a conjugate containing a biologically active agent that is covalently attached to a transport polymer. In one embodiment, the polymer consists of from 6 to 25 subunits, at least 50% of which contain a guanidino or amidino sidechain moiety. The polymer is effective to impart to the attached agent a rate of trans-membrane transport across a biological membrane that is greater than the rate of trans-membrane transport of the agent in nonconjugated form.
