Bioactive coatings that are stabilized against inactivation by weathering are provided including a base associated with a chemically modified enzyme, and, optionally a first polyoxyethylene present in the base and independent of the enzyme. The coatings are optionally overlayered onto a substrate to form an active coating facilitating the removal of organic stains or organic material from food, insects, or the environment.

The invention provides a non-particulate cross-linked poly--lysine polymer. The poly--lysine and cross linker are linked by amide bonds and may the cross linker has at least two functional groups capable of reacting with an alpha carbon amine of poly--lysine. The polymer is suitably insoluble in water and other solvents and is provided in macro form for example a sheet, article or fiber. The macro form polymer is useful in a wide range of applications including wound treatment, as a medical diagnostic comprising a particulate support and a functional material bound or retained by the support and solid phase synthesis of peptides, oligonucleotides, oligosaccharides, immobilisation of species, cell culturing and in chromatographic separation.

Provided is a method for capture and release of microorganisms using microstructures. The method includes providing microstructures coated with a protein for attachment/detachment of microorganisms, mixing the microstructures with a solution containing substances assisting in attachment of microorganisms in a solution containing microorganisms to prepare a mixed solution, stirring the mixed solution to attach the microorganisms to the microstructures, separating the microorganism-attached microstructures from the mixed solution; and exposing the microstructures to an environment where the substances assisting in attachment of the microorganisms are present at a low concentration to detach the microorganisms from the microstructures.
