Journal ArticleDOI
A biosensor that uses ion-channel switches
Bruce Cornell,Vijoleta Lucija Bronislava Braach-Maksvytis,Lionel G. King,P. D. J. Osman,Burkhard Raguse,Lech Wieczorek,Ronald Pace +6 more
TL;DR: In this article, the authors describe the development of a biosensing technique in which the conductance of a population of molecular ion channels is switched by the recognition event, which mimics biological sensory functions and can be used with most types of receptor, including antibodies and nucleotides.
Journal ArticleDOI
Tethered Lipid Bilayer Membranes: Formation and Ionic Reservoir Characterization
Burkhard Raguse,Vijoleta Lucija Bronislava Braach-Maksvytis,Bruce Cornell,Lionel G. King,Peter Osman,and Ron J. Pace,Lech Wieczorek +6 more
TL;DR: In this paper, a tethered bilayer membrane (tBLM) was formed onto a gold electrode such that a well-defined ionic reservoir exists between the gold surface and the bilayer membranes.
Journal ArticleDOI
Nanoparticle films as sensitive strain gauges
J. Herrmann,K.-H. Müller,T. Reda,G. R. Baxter,Burkhard Raguse,G. J. J. B. de Groot,Roger Chai,M. Roberts,Lech Wieczorek +8 more
TL;DR: In this paper, the authors demonstrate that thin films consisting of cross-linked nanoparticle aggregates function as highly sensitive strain gauges and exploit the exponential dependence of the interparticle tunnel resistance on the particle separation.
Journal ArticleDOI
Fabrication of Hollow Metal “Nanocaps” and Their Red‐Shifted Optical Absorption Spectra
Journal ArticleDOI
Gold nanoparticle chemiresistor sensors: direct sensing of organics in aqueous electrolyte solution.
TL;DR: A novel chemiresistor sensor for detection of organic analytes in high-conductivity aqueous electrolyte solution is reported, based on thin films of gold nanoparticles capped with a 1-hexanethiol monolayer that is inkjet printed onto a microelectrode.
