Patent number: 10073037Abstract: The invention relates to the use of a construct for the detection of an analyte using surface enhanced spectroscopic techniques. The construct includes linked surfaces, where the link is formed by a linker providing a fixed inter-surface separation between the linked surfaces, wherein the linker is a linking compound, and at least one of the surfaces is the surface of a nanoparticle. The linking compound is suitable for interacting with the analyte. The linking compound may be a cucurbituril. The surface enhanced spectroscopic technique may be surface enhanced Raman spectroscopy (SERS).Type: GrantFiled: June 24, 2011Date of Patent: September 11, 2018Inventors: Richard William Taylor, Jeremy John Baumberg, Sumeet Mahajan, Tung-Chun Lee, Oren Alexander Scherman, Setu Kasera, Roger Coulston

Publication number: 20170028374Abstract: Provided is a capsule having a shell of material that is a supramolecular cross-linked network. The network is formed from a host-guest complexation of cucurbituril (the host) and one or more building blocks comprising suitable guest functionality. The complex non-covalently crosslinks the building block and/or non-covalently links the building block to another building block thereby forming the supramolecular cross-linked network. The capsules are obtained or obtainable by the complexation of a composition comprising cucurbituril and one or more building blocks having suitable cucurbituril guest functionality thereby to form a supramolecular cross-linked network.Type: ApplicationFiled: July 29, 2016Publication date: February 2, 2017Applicant: CAMBRIDGE ENTERPRISE LIMITEDInventors: Oren Alexander SCHERMAN, Roger COULSTON, Christopher ABELL, Jing ZHANG

Patent number: 9227980Abstract: A method for purifying a cucurbituril from a mixture. The method includes the step of forming a complex between the cucurbituril and a cucurbituril guest. The complex has altered physical and/or chemical properties to the cucurbituril which allow the complex to be separated from at least one other component of the mixture. The mixture includes the cucurbituril, the other component and a solvent.Type: GrantFiled: December 23, 2010Date of Patent: January 5, 2016Assignee: CAMBRIDGE ENTERPRISE LIMITEDInventors: Oren Alexander Scherman, Dezhi Jiao, Nan Zhao

Patent number: 8378059Abstract: This invention pertains generally to supramolecular polymers comprising a polymeric molecule linked to a first CB[8] guest molecule and an attachment compound linked to a second CB[8] guest molecule, wherein the first and second CB[8] guest molecules form a ternary host-guest complex with a CB[8] molecule which non-covalently links the polymeric molecule and the attachment compound in a supramolecular polymer. These polymers are useful as vehicles for delivery of a therapeutic compound for use in a method of treatment of the human or animal body, in particular for use in a method of delivering the therapeutic compound to a target site in an individual. The invention also provides methods for the preparation of the supramolecular polymers.Type: GrantFiled: December 4, 2008Date of Patent: February 19, 2013Assignee: Cambridge Enterprise Ltd.Inventors: Urs Rauwald, Oren Alexander Scherman
