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.
The characteristics of the binding reaction of surfactant-cobalt(III) complex, cis-[Co(phen)(2)(C14H29NH2)]Cl-2 center dot 3H(2)O (phen =1,10-phenanthroline, C14H29NH2 = tetradecylamine) with human serum albumin (HSA) were studied by fluorescence and UV-vi ...
We investigate two-photon-induced fluorescence for organic chromophores next to elongated gold disks which support plasmonic resonances. By polyelectrolyte coating, the dye is placed in a defined concentration at a defined distance from the surface. A fluo ...
Single-molecule Forster resonance energy transfer (FRET) and photoinduced electron transfer (PET) have developed into versatile and complementary methods for probing distances and dynamics in biomolecules. Here we show that the two methods can be combined ...
Synthesis of Modified Prolines using aza naked sugar methodology R and S-prolines are secondary, cyclic, pyrrolidine-based amino acids. Proline demonstrated excellent catalytic activity to promote enantio- and diatereoselective, intra- and intermolecular c ...
Fluorescence resonance energy transfer (FRET) efficiency measurements based on acceptor photobleaching of yellow fluorescent protein (YFP) are affected by the fact that bleaching of YFP produces a fluorescent species that is detectable in cyan fluorescent ...
Triplet, photo-oxidized and other photoinduced, long-lived states of fluorophores are sensitive to the local environment and thus attractive for microenvironmental imaging purposes. In this work, we introduce an approach where these states are monitored in ...
A novel imaging method employing the different kinetics of the energetic states of fluorescent markers is presented, where the contrast depends on the triplet kinetics. An attractive feature of triplet states is their long lifetime, rendering them highly s ...
Planar mutilayers sustaining either TE or TM polarized Bloch Surface Waves (BSWs) offer new opportunities for management of light at the nanoscale. We will discuss how BSWs can be exploited in guiding and confining light on nanometric relieves, enhancing f ...
We report for the first time the absorption and fluorescence spectra of gold dimers in a neon matrix. The dimer absorption spectra show the A←X transition predicted from measurements in the gas phase and not observed so far in a matrix, as well as the so-c ...
Coherent manipulation of molecular wavepackets in biomolecules might contribute to the quest towards label-free cellular imaging and protein identification. We report the use of optimally tailored UV laser pulses in pump-probe depletion experiments that se ...
