    Abstract: Using a novel water-soluble, active ester amide-containing functionalized controlled radical polymerization initiator, stimuli responsive polymers have been grown from the surface of a protein, exemplified by chymotrypsin or any protein having surface amino acids that will covalently bind to the active ester amide-containing functionalized initiator. It is shown that changes in temperature or pH can change the conformation of the polymer surrounding the enzyme, which in turn enabled the rational tailoring of enzyme activity and stability. This method has afforded an increase in the activity and stability of the enzyme by an order of magnitude at pH's where the enzyme is usually inactive or unstable. Multimodal temperature responsive protein-block copolymer conjugates are described.

    Abstract: The present invention relates to biocidal articles. In an embodiment the biocidal article comprises a plurality of polymers having biocidally active groups. The polymers are attached to a surface and may have a polydispersity less than 3. The biocidally active groups may comprise at least one of a quaternary ammonium salt, a quaternary phosphonium salt or a chloroamine. The attached polymers may be any microstructure, topology or composition, such as, a homopolymer, block copolymer, multiblock copolymer, a random copolymer, graft polymer, a branched or a hyperbranched polymer, and a gradient copolymer. The present invention also comprises a process for the preparation of a biocidal article. Embodiments of the process comprise polymerizing radically polymerizable monomers from an initiator attached to a surface, wherein at least a portion of the monomers comprise a group capable of being converted to a biocidally active group, and converting the group to the biocidally active group.

    Abstract: The invention concerns the synthesis of nanotubes and nanocarpets composed of single chain achiral diacetylenes under conditions where individual molecules form supra molecular associations. Self-assembly is a coordinated association of individual molecules into a defined (usually non-covalent) structure without the intervention of a central controller. Self assembly presumes the ability of a molecule, or group of molecules, to assume a stable or quasi stable structure based solely on the structure of the molecules themselves. The driving force in self-assembling systems is that the supramolecular structure achieves a lower energy state than the individual components alone.

    Abstract: The invention provides methods for preparing a stable, multiple-use three enzyme biosensor for the amperometric determination of creatinine in biological liquids that has a useful lifetime that extends significantly beyond that of presently available amperometric biosensors. The biosensor prepared by the methods of the invention encompasses a plurality of immobilized enzymes that are applied to the biosensor as an enzyme-polymer composition. The enzymes, which can include creatinine amidohydrolase, creatine amidinohydrolase and sarcosine oxidase, are immobilized into the enzyme-polymer composition simultaneously as well as applied to the biosensor simultaneously. Prior to being immobilized, the enzymes can be chemically modified by attaching one or more polyethylene glycol (PEG) chains per enzyme monomer. The polymer component can be provided by a polyurethane membrane. The invention also provides a method of preparing a biosensor that limits the diffusion of silver ions emanating the reference electrode, thereby preventing, contact between the silver ions and the enzymes. Related methods of preparing an enzyme-polymer composition for incorporation into a multiple use three enzyme biosensor for the amperometric determination of creatinine in biological liquids also are provided. The invention also provides multiple-use biosensors and enzyme-polymer compositions prepared by the methods disclosed.
