Abstract: Polymer particles are formed containing molecular memory recognition sites and magnetically susceptible components. The particles are prepared by co-polymerizing one or more monomers and a cross-linking agent in the presence of at least one imprint molecule and at least one magnetically susceptible component such as iron oxide or nickel oxide, and removing the imprint molecule to form molecular memory recognition sites. The particles are also prepared by co-polymerizing the monomer and cross-linking agent in the presence of the imprint molecule to produce particles, removing the imprint molecule and associating magnetically susceptible components with the particles. The particles may also be prepared containing selective adsorbents such as cells or antibodies. The particles are used for selective adsorption of a product such as separating and resolving two different enantiomeric forms due to one of the forms adsorbing to a memory recognition site created by using the form as an imprint molecule.

Abstract: Paucilamellar lipid vesicles containing lipid bilayers at least two lipid bilayers formed of surfactant materials, each of the bilayers comprising a glucoside primary amphiphile and a steroid. The vesicles may have either an aqueous or oil-filled central cavity and are particularly useful for delivering dermatological, cosmetic and pharmaceutical formulations. A method of manufacture for these vesicles is also disclosed.

Abstract: Disclosed and claimed are methods for selecting a recombinant virus, phage or cell expressing a catalytic antibody or catalytic portion thereof, or for selecting catalytic activity by a moiety. The method employs reaction-based selection for catalytic activity. The method can also be used to concentrate (increase the proportion of catalytic to non-catalytic moieties) a sample containing a catalytic moiety or viruses, phages or cells expressing a catalytic moiety. The selection or concentrating can be by employing a mechanism-based inhibitor, catalysis-accelerated movement, surface binding, changes in enthalpic component of binding as a function of temperature, or changes in binding by competition, or combinations thereof. The invention also comprehends a method for producing a recombinant virus or a cell-line expressing a catalytic moiety such as a catalytic antibody or catalytic portion thereof; and, this method can include infecting a suitable host with viruses which are screened for the expression.
