Abstract: Methods of modulating interfacial characteristics in a self-assembled, force-transmitting peptide network at a fluid-fluid interface are disclosed. The methods involve exposing a peptide capable of participating in a self-assembled, force-transmitting peptide network, either before or after it interacts with other peptides to form the peptide network to a stimulus that alters the chemical and/or physical properties of the peptide. Use of such methods in applications such as emulsions and foams are also disclosed.

Abstract: A hydrogel microdome that can swell in response to a stimuli or target molecule is formed by polymerizing a mixture comprising a monomer capable of forming a hydrogel with a biopolymer. An array of hydrogel microdomes can be formed on a substrate by microspotting the mixture and polymerizing. The array can be used for high-throughput screening of analytes as well as for use as an actuator and biosensor using the swelling property of the hydrogel.

Abstract: The invention relates to a water-thin emulsion comprising a non-phospholipid, non-ethoxylated pseudoemulsifier system, the system having a chemical composition with at least one hydrophobic moiety and at least one polar moiety, the size, shape and/or planar arrangement of the hydrophobic and polar moieties being asymmetrical with respect to each other. The emulsion of the invention is prepared by high-pressure homogenization of a crude oil and water emulsion containing the pseudoemulsifier. The emulsions require little or no traditional emulsifier to maintain stability, and are particularly useful in the preparation of multiple emulsions.

Abstract: A method of producing protein stabilised emulsions comprising the steps of decreasing the pH of a protein solution by the addition of an acidic solution to convert it to a cationic form, heating the solution until the protein is solubilised, and then adding a lipid. The lipid is typically any fractionated or partially purified protein but may also comprise a mixture of proteins. The protein must be in a cationic form. There is also provided an oil in water emulsion and water in oil in water emulsion, made by the method.

Abstract: The invention relates to fine emulsions comprising at least one W/O emulsifier and at least one hydrophilic component, and to a process for their preparation. The fine emulsions are obtainable by converting a W/O preemulsion comprising at least one W/O emulsifier into an O/W fine emulsion by adding at least one hydrophilic component and, where appropriate, changing the temperature. Suitable W/O emulsifiers are preferably sorbitol esters. The fine emulsions are preferably spray emulsions for cosmetic and pharmaceutical applications.

Abstract: A lock unimolecular micelle includes at least one engineered acceptor specifically binding a ligand (or specifically a “key” unimolecular micelle) thereto. A key unimolecular micelle comprises a core molecule and a plurality of branches extending therefrom, at least one of the branches including a shank portion extending therefrom having a terminal moiety at an end thereof for binding to a complimentary acceptor of a lock unimolecular micelle. Together, the lock and key micelles form a unit, either irreversibly or reversibly bound wherein the lock micelles is a soluble receptor engineered to specifically bind to the specifically engineered key micelle.

Abstract: Externally emulsified aqueous resole dispersions obtained by reacting phenols and oxo compounds in the presence of an alkaline catalyst, adding an emulsifier and then dispersing in water, the catalyst used during resole formation comprising aliphatic linear, branched or cyclic tertiary monohydroxyamines having from 4 to 40 carbon atoms, and their use as binders for abrasives, particularly abrasives on backings.

Abstract: A composition comprising xanthan gum particles coated with a mixture of zein (corn protein) and at least one emulsifier. The surface coating improves the dispersion and hydration of xanthan gum resulting in shorter mix times for the user of the xanthan gum. Moreover, the xanthan gum powder dispersibility and hydration properties may be tailored by modifying the amounts of the zein and emulsifier in the coating blend. In addition, there is a significant fine particle reduction with the coated xanthan gum.

Abstract: A composition and a method for treatment of prostate related dysfunction and, particularly, non-bacterial prostatitis and, even more particularly, non-bacterial chronic prostatitis.
