Patent number: 9150646Abstract: A coating for a surface of a surgical implant, the coating including a binding protein for capturing cells to the surface via a bi-functional linker molecule. The linker can have a first functional group (such as a trichlorosilyl group) for covalently linking to the surface, and a second functional group (such as a benzothiosulfonate group) for covalently linking to the binding protein. One exemplary linker molecule is S-(11-trichlorosilyl-undecenyl)benzenethiosulfonate. The coating may be a self-assembled monolayer and may also include a spacer molecule, which can be unreactive with the binding protein. The target cells may be endothelial stem cells (such as endothelial progenitor cells). The binding protein may be an antibody, antibody fragment or non-antibody derived antigen binding molecule. The binding protein may bind a cell surface marker specific to target cell type. Coated surgical implants, and methods of forming such a coating are also contemplated.Type: GrantFiled: September 12, 2011Date of Patent: October 6, 2015Assignee: Econous Systems Inc.Inventors: Michael Thompson, Pasquale Benvenuto, Christophe Blaszykowski

Patent number: 9078956Abstract: A surface-modified polymer is described, comprising a polymeric material and a self-assembling monolayer covalently bound thereto. The monolayer comprises monoethylene glycolated-OH (MEG-OH); 2-(3-trichlorosilyl-propyloxy)-ethyl-trifluoroacetate (7-OEG or MEG-TFA); 2,2,2-trifluoroethyl-13-trichlorosilyl-tridecanoate (TTTA); OEGylated TTTA (OEG-TTTA); S-(2-(2-(2-(3-trichlorosilyl-propyloxy)-ethoxy)-ethoxy)-ethyl)-benzenethiosulfonate (OEG-TUBTS); or a combination thereof. Methods are described for forming a surface-modified polymer by surface activation, such as with plasma. By utilizing the surface-modified polymer to make medical equipment or devices for contacting biological fluids, a reduction in surface fouling and thrombus formation can result. Advantageously, polymeric equipment or components so modified may have a reduction in unwanted chemical interactions leading to fouling or clotting.Type: GrantFiled: July 4, 2013Date of Patent: July 14, 2015Assignee: Econous Systems Inc.Inventors: Michael Thompson, Sonia Sheikh, Jack Chih-Chieh Sheng, Christophe Blaszykowski, Kiril Fedorov

Patent number: 8491958Abstract: An acoustic wave biosensor comprising a surface of a mixed self-assembling monolayer for receiving a probe-biomolecule is described herein. The biosensor surface may comprise a piezoelectric quartz crystal,—for detection purposes with the electromagnetic piezoelectric acoustic sensor (EMPAS)—upon which a mixed self-assembling monolayer is formed, which includes at least one linker, such as 2,2,2-trifluoroethyl-13-trichlorosilyl-tridecanoate (TTTA); its oligoethylene glycol (OEG) analog OEGylated TTTA (OEG-TTTA); S-(2-(2-(2-(3-trichlorosilyl-propyloxy)-ethoxy)-ethoxy)-ethyl)-benzenethiosulfonate (OEG-TUBTS). Linker/diluent systems for attaching a functionalizing entity to the surface of a biosensor are described, as well as methods for preparing a biosensor surface with an oligoethylene glycol linker.Type: GrantFiled: June 6, 2011Date of Patent: July 23, 2013Assignee: Econous Systems Inc.Inventors: Michael Thompson, Sonia Sheikh, Jack Chih-Chieh Sheng, Christophe Blaszykowski
