Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Targeted Photoswitchable Probe for Nanoscopy of Biological Structures

Theo Lasser, Kai Johnsson, Iwan Märki, Stefan Geissbühler, Noelia Laura Bocchio, Grazvydas Lukinavicius, Claudio Dellagiacoma, Sambashiva Banala

We introduce a photoswitchable O6-benzylguanine derivative and demonstrate its use for super-resolution microscopy of SNAP-tagged proteins based on single fluorophore localization. Stochastic Optical Reconstruction Microscopy (STORM) reveals SNAP-tagged mi ...

Reusable Localized Surface Plasmon Sensors Based on Ultrastable Nanostructures

Noelia Laura Bocchio

Nanoparticle arrays created by nanosphere lithography are widely used in sensing applications since their localized surface plasmon resonances are extremely sensitive to changes in the local dielectric environment. A major drawback for any biologically ori ...

The use of fluorescence light for far-field imaging at the nanometer scale has drawn much attention worldwide. Example techniques include STED microscopy and localization microscopy (PALM, STORM). Typically, nanoscopy approaches have been focused on the ma ...

2009

Metallic nanostructures show interesting optical properties due to their plasmonic resonances, and when arranged in three-dimensional (3D) arrays hold promise for optical metamaterials with negative refractive index. Towards this goal a simple, cheap, and ...

Controlled Polyelectrolyte Coating of Glass-Supported Metal Nanostructures

Noelia Laura Bocchio

We investigated the coating of glass-supported gold nanostructures with polyelectrolyte multilayers. To achieve selective coating of either the metal or the glass, thiol and silane monolayers with different functionalities were used. Self-assembled monolay ...

2009

Gold crescent-shaped nanoparticles, exhibiting multiple resonances in the visible and near-infrared spectral region, were characterized in terms of their optical response to thin dielectric coatings. A strong red shift of the resonances is observed upon th ...

Photonic mode density effects on single-molecule fluorescence blinking

Noelia Laura Bocchio

We investigated the influence of the photonic mode density (PMD) on the triplet dynamics of individual chromophores on a dielectric interface by comparing their response in the presence and absence of a nearby gold film. Lifetimes of the excited singlet st ...

Tuning resonances on crescent-shaped noble-metal nanoparticles

Noelia Laura Bocchio

The geometry of crescent-shaped noble-metal nanoparticles is systematically varied in terms of shape and size. The resulting changes in the plasmonic resonances of these structures are investigated by extinction spectroscopy revealing a rich polarization-d ...

Institute of Physics (IoP) and Deutsche Physikalische Gesellschaft2007

We demonstrate that fluorescence of single molecules in the nanometric vicinity of a thin gold film can be effectively excited and detected through the film with an epi-illumination scanning confocal micro- scope. A full theoretical treatment of the fluore ...
