Supramolecular architectures for the functionalization of solid surfaces

Advances in Biophysics, 1997
Surface plasmon optical techniques are described as sensitive tools that allow for the on-line characterization of supramolecular biofunctional architectures at solid/solution interfaces. After a short introduction into the fundamentals of surface plasmon optics the observation of the build up of a functional bio-interface by the self-assembly process ...

Ultrathin layers and supramolecular architecture of isopentylcellulose

Macromolecules, 1995
The characterization of multilayers from tri-O-isopentyl cellulose assembled by the Langmuir-Blodgett technique is described. The analysis of ultrathin films by X-ray reflection confirmed a homogeneous overall film quality but did not show any Bragg reflection. However, investigation of a superstructure in terms of an alternating multilayer sample from

Amperometric biosensor for xanthine with supramolecular architecture

Chem. Commun., 2007
Xanthine oxidase modified with 1-adamantanyl residues was supramolecularly immobilized on Au electrodes coated with Au nanoparticles coated with a perthiolated beta-cyclodextrin polymer; the analytical response of the electrode toward xanthine was evaluated.

Anion−π Interactions in Supramolecular Architectures

Accounts of Chemical Research, 2013
The study of the noncovalent force between π-acidic aromatic systems and anions, referred to as the anion-π interaction, has recently emerged as a new branch of supramolecular chemistry. The anion-π contact is complementary to the cation-π interaction, a prominent noncovalent force involved in protein structure and enzyme function.

Photoactive amphiphiles for the assembly of supramolecular architectures

Faraday Discussions, 2015
The presented study reports the use of photoactive templating structures for the design of porous frameworks with built-in optical functionalities. The materials have been synthesised and characterised using powder X-ray diffractometry, UV-visible absorption and emission spectroscopy.

A sensitive choline biosensor with supramolecular architecture

Talanta, 2010
A sensitive biosensor with supramolecular architecture was designed and implemented here to detect choline. Choline oxidase and horseradish peroxidase were assembled onto the polymer of thiolated beta-cyclodextrin and platinum nanoparticles modified gold electrode through 1-adamantane carboxylic acid coupling.

Combination of orthogonal supramolecular interactions in polymeric architectures

Chemical Communications, 2005
Supramolecular polymers represent a highly interesting approach towards new "smart materials". A recent strategy includes the combination of different "orthogonal" non-covalent binding sites within one polymer system. Different functionalities can be introduced in a highly defined way by controlled self-assembly processes. This feature article presents

An inexpensive approach to supramolecular architecture

Chemical Communications, 1997
A new approach to generating supramolecular architectures, based on inexpensive and easy-to-prepare imine ligands, is described together with its application to the self-assembly of supramolecular triple-helicates.

Supramolecular interfacial architectures for biosensing

SPIE Proceedings, 2004
This contribution summarizes some of our efforts in designing, assembling and functionally characterizing supramolecular interfacial architectures for bio-affinity studies and for biosensor development. All the surface interaction studies will be based on the recently introduced novel sensor platforms involving surface plasmon fluorescence spectroscopy

Structural Characterization of Modular Supramolecular Architectures in Solution

Journal of the American Chemical Society, 2004
Structures of modular supramolecular architectures consisting of a hexameric, diphenylethyne-linked porphyrin macrocyclic array and the corresponding host-guest complex formed by inclusion of a tripyridyl guest molecule were characterized in solution using high-angle X-ray scattering.
