Abstract: The present invention provides a composition comprising an antimicrobial bilayer coating on a substrate which coating comprises: (1) a polyionic material, in alternating layers, where one layer is a cationic polymer containing —NHR1 or —C(O)NHR2 groups, where R1 and R2 are independently hydrogen, straight- or branch-chain C1-C10 alkyl, phenyl, benzyl, or C6-C14 aryl; and another layer is an anionic polymer containing —COOH or —COOR groups, where R is straight- or branch-chain C1-C10 alkyl, phenyl, benzyl, or C6-C14 aryl; and (2) At least two full bilayers are coated on the substrate; and (3) the layers are crosslinked through amide, imide, urea, or carbamate bonds; and (4) at least 1% of the amine or amide N—H groups in the coating are converted to N—X, where X is Cl or Br. The bilayers, where an anionic outermost layer is present, is preferred. These coating compositions, applied to a substrate, are then crosslinked and finally treated with aqueous hypochlorite when N—X is N—Cl.

Abstract: An improved synthetic blood substitute which exhibits excellent long-term storage stability at both high and low temperatures is suitable for use in various biomedical and biotechnical applications, including resuscitation of trauma victims that have suffered massive hemorrhaging, and transfusions for human and veterinary surgical procedures. The artificial blood solution comprises an aqueous carrier, and a dendritic polymer that is capable of carrying oxygen dissolved in the aqueous carrier. The dendritic polymer comprises fluorocarbon moieties and hydrophilic moieties.

Abstract: Solid-state colorimetric biosensors having sensory groups and interdendritic cross-linking segments of alternating conjugated double and triple bonds are prepared by intermolecular polymerization of diacetylene-functionalized dendritic polymer precursors. The polymerization process may be used to form solid films that are capable of indicating the presence of an analyte by a detectable change in color. The disclosed solid-state colorimetric biosensors may exhibit excellent stability at elevated temperatures and in the presence of organic solvents, and due to the dendritic architecture and high density of sensing functionality achieve high sensitivity to analytes.

Abstract: Molecular chemical and/or biological sensors that exhibit a very high density of sensing functionality and which are applicable to a wide variety of different analytes, and enable rapid, convenient and economical detection of analytes are prepared by reacting a dendritic polymer with a diacetylene reagent wherein the diacetylene functional groups are subsequently intramolecularly polymerized to form segments having alternating conjugated double and triple bonds. Sensory groups that can bind with an analyte are bonded to the acetylene monomer units to form molecular sensors that produce observable and measurable color changes when an analyte binds with the sensory groups.

Abstract: The present invention is a sorbent polymer with the (AB)n sequence where the fluorinated interactive A segment is fluoroalkyl-substituted bisphenol and the oligosiloxane B segment is an oligodimethylsiloxane. More specifically, the fluoroalkyl-substituted bisphenol contains two allyl groups and the oligodimethylsiloxane has terminal Si--H groups. The sorbent polymer may be used as thin films on a variety of chemical sensors, or as a component of a thin film on a chemical sensor. Crosslinked sorbent polymers are processable into stable thin films on sensor devices. Sorbent polymers are also useful in sensor arrays, in surface acoustic wave sensors, and in cladding of optical fibers. Sensor arrays provide better selectivity than single sensors and permit identification and quantification of more than one species in a mixture. The sorbent polymer is synthesized by hydrosilylation polymerization which is achieved by catalyzed heating.
