Abstract: A decomposable thin film comprising a plurality of alternating layers of net positive and negative charge. At least a portion of the positive layers, the negative layers, or both, comprise a polyelectrolyte.

Abstract: A linear-dendritic hybrid polymer for encapsulating biologically active materials. The hybrid polymer includes a ligand for a predetermined target, a dendron, and a polyethylene glycol (PEG) chain linking the ligand to the dendron.

Abstract: One aspect of the invention provides ion-exchange and gas-diffusion membranes, fabricated by a layer-by-layer approach, for use, e.g., in electrochemical cells; a process for making membrane electrode assemblies fabricated using porous frameworks, LBL composite membranes and LBL carbon-Polymer electrodes; and the application of the membrane and electrode assemblies to a variety of devices, both electrochemical and otherwise.

Abstract: One aspect of the present invention relates to an array of non-adhesive cells, comprising a polymeric substrate, an array of a graft copolymer bound to the polymeric substrate, an antibody bound to the polymeric substrate in an area of the polymeric substrate not covered by the graft copolymer, and a non-adhesive cell bound to the antibody. Another aspect of the present invention relates to a method of preparing an array of non-adhesive cells, comprising depositing an array of a graft copolymer upon a polymeric substrate; binding an antibody to an area of the polymeric substrate not covered by the graft copolymer; and binding a non-adhesive cell to the antibody.
