Journal ArticleDOI
Stepwise quenching of exciton fluorescence in carbon nanotubes by single-molecule reactions.
Laurent Cognet,Laurent Cognet,Dmitri A. Tsyboulski,Dmitri A. Tsyboulski,John-David R. Rocha,John-David R. Rocha,Condell D. Doyle,Condell D. Doyle,James M. Tour,James M. Tour,R. Bruce Weisman,R. Bruce Weisman +11 more
TL;DR: Single-molecule chemical reactions with individual single-walled carbon nanotubes were observed through near-infrared photoluminescence microscopy, providing highly efficient sensing of local chemical and physical perturbations.
Journal ArticleDOI
Carbon nanotube-enhanced thermal destruction of cancer cells in a noninvasive radiofrequency field
Christopher J. Gannon,Paul Cherukuri,Boris I. Yakobson,Laurent Cognet,John Kanzius,Carter Kittrell,R. Bruce Weisman,Matteo Pasquali,Howard K. Schmidt,Richard E. Smalley,Steven A. Curley,Steven A. Curley +11 more
TL;DR: A novel property of SWNTs—heat release in a radiofrequency (RF) field)—that they hypothesized may be used to produce thermal cytotoxicity in malignant cells is discovered.
Journal ArticleDOI
Differential activity-dependent regulation of the lateral mobilities of AMPA and NMDA receptors.
Laurent Groc,Martin Heine,Laurent Cognet,Kieran Brickley,F. Anne Stephenson,Brahim Lounis,Daniel Choquet +6 more
TL;DR: Different lateral mobilities for AMPARs and NMDARs are found: changes in neuronal activity modified AMPAR but not NMDar mobility, whereas protein kinase C activation modified both.
Journal ArticleDOI
Surface Mobility of Postsynaptic AMPARs Tunes Synaptic Transmission
Martin Heine,Laurent Groc,Renato Frischknecht,Jean-Claude Béïque,Brahim Lounis,Gavin Rumbaugh,Richard L. Huganir,Laurent Cognet,Daniel Choquet +8 more
TL;DR: It is shown that AMPAR lateral diffusion, observed in both intact hippocampi and cultured neurons, allows fast exchange of desensitized receptors with naïve functional ones within or near the postsynaptic density, which can be explained in part by this fast receptor exchange.
Journal ArticleDOI
Direct imaging of lateral movements of AMPA receptors inside synapses
TL;DR: The data show that rapid exchange of receptors between a synaptic and extra‐synaptic localization occurs through regulation of receptor diffusion inside synapses, and that this process is driven by inhibition of inhibitory transmission to favor excitatory synaptic activity.
