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.
We describe and demonstrate a new oscillator topology, the parametric feedback oscillator (PFO). The PFO paradigm is applicable to a wide variety of nanoscale devices and opens the possibility of new classes of oscillators employing innovative frequencydet ...
Surface plasmon resonance (SPR) was observed when a planar close-packed assembly of gold nanoparticles (Au NPs) is adsorbed at the water|1,2-dichloroethane interface. Aqueous gold nanoparticles, 13 or 16 nm in diameter, are deposited at the interface by ad ...
A class of peptides from the bombolitin family, not previously identified for nitroaromatic recognition, allows near-infrared fluorescent single-walled carbon nanotubes to transduce specific changes in their conformation. In response to the binding of spec ...
Optical limiting by suspensions of Au nanoparticles is enhanced by several orders of magnitude with the use of complex plasmonic shapes, such as spined 'nanourchins,' instead of nanospheres. Similar enhancements are observed by changing the material of nan ...
The authors use glucose-binding protein (GBP) to mech. actuate a fluorescent single-walled carbon nanotube (SWNT), resulting in reversible exciton quenching in response to glucose. The GBP is covalently conjugated with carboxylated poly(vinyl alc.)-wrapped ...
The Optical trapping of Au nanoparticles with dimensions as small as 10 nm in the gap of plasmonic dipole antennas is demonstrated. Single nanoparticle trapping events are recorded in real time by monitoring the Rayleigh scattering spectra of individual pl ...
In recent work, the authors have shown that d(AT)15 DNA-wrapped single-walled carbon nanotubes (SWNTs) are able to detect the adsorption and desorption of single mols. of nitric oxide (NO) from the surface by quenching of the near-IR fluorescence. A centra ...
The lanthanide binuclear helicate [Ln(2)(L-C2)(3)] has been embedded into bare and NH2-functionalized silica nanoparticles (NPs) using water-in-oil microemulsion technique. TEM analysis reveals both [Ln(2)(L-C2)(3)]@SiO2 and [Ln(2)(L-C2)(3)]@SiO2/NH2 nanop ...
This work focuses on trapping subwavelength objects using resonant plasmonic structures. Trapping entities include latex spheres, living cells and metallic particles; the plasmonic structures involved include subwavelength disks, subwavelength apertures, a ...
In this paper, we introduce a novel sensor scheme which merges nano-photonics and nano-fluidics on a single platform through the use of free-standing photonic crystals (PhCs). PhCs offer great freedom to manipulate the spatial extent and the spectral chara ...
