Ultraviolet Superradiance from Mega-Networks of Tryptophan in Biological Architectures
Majed Chergui, Katrin Elisabeth Oberhofer
Networks of tryptophan (Trp)& horbar;an aromatic amino acid with strong fluorescence response & horbar;are ubiquitous in biological systems, forming diverse architectures in transmembrane proteins, cytoskeletal filaments, subneuronal elements, photorecepto ...
Amer Chemical Soc2024DNA-Liposome Hybrid Carriers for Triggered Cargo Release
The design of simple and versatile synthetic routes to accomplish triggered-release properties in carriers is of particular interest for drug delivery purposes. In this context, the programmability and adaptability of DNA nanoarchitectures in combination w ...
AMER CHEMICAL SOC2022Thiazole Boron Difluoride Dyes with Large Stokes Shift, Solid State Emission and Room-Temperature Phosphorescence
Jieping Zhu, Wei Wang, Shuo Tong
The small Stokes shift and weak emission in the solid state are two main shortcomings associated with the boron-dipyrromethene (BODIPY) family of dyes. This study presents the design, synthesis and luminescent properties of boron difluoro complexes of 2-ar ...
WILEY-V C H VERLAG GMBH2022Chemistry and Analysis of Nanoparticle-Modified Living Cells
Conventional therapeutics are often limited by their targeting ability, resulting in harmful and potential fatal side-effects for the patients. Recently, new strategies have been developed to improve target specificity of drugs in order to generate more ef ...
EPFL2020Single-Photon, Time-Gated, Phasor-Based Fluorescence Lifetime Imaging through Highly Scattering Medium
Edoardo Charbon, Claudio Bruschini, Arin Can Ülkü
Fluorescence lifetime imaging (FLI) is increasingly recognized as a powerful tool for biochemical and cellular investigations, including in vivo applications. Fluorescence lifetime is an intrinsic characteristic of any fluorescent dye which, to a large ext ...
AMER CHEMICAL SOC2020Simplified Instrument Calibration forWide-FieldFluorescence Resonance Energy Transfer (FRET) Measured by the Sensitized Emission Method
Forster (or fluorescence) resonance energy transfer (FRET) is a quantifiable energy transfer in which a donor fluorophore nonradiatively transfers its excitation energy to an acceptor fluorophore. A change in FRET efficiency indicates a change of proximity ...
2020A multi-scale time-resolved study of photoactivated dynamics in 5-benzyl uracil, a model for DNA/protein interactions
Majed Chergui, Enrico Pomarico, Mohammadhassan Valadan
We combine fluorescence up-conversion and time correlated single photon counting experiments to investigate the 5-benzyl uracil excited state dynamics in methanol from 100 fs up to several ns. This molecule has been proposed as a model for DNA/protein inte ...
2019Mechanisms of fluorescence quenching in prototypical aggregation-induced emission systems: excited state dynamics with TD-DFTB
Antonio Prlj, Kun-Han Lin, Daniel Hollas, Thierry Tran
A recent implementation of time-dependent tight-binding density functional theory is employed in excited state molecular dynamics for the investigation of the fluorescence quenching mechanism in 3 prototypical aggregation-induced emission systems. An asses ...
ROYAL SOC CHEMISTRY2019Exploring Energy Transfer in a Metal/Perovskite Nanocrystal Antenna to Drive Photocatalysis
Raffaella Buonsanti, Mounir Driss Mensi, Anna Loiudice, Seryio Saris
The use of all-inorganic perovskite nanocrystals (PeNCs) in photocatalytic systems has been limited because of their instability in polar solvents. Encapsulation of PeNCs in inorganic or polymeric matrices has been shown to be effective in overcoming such ...
AMER CHEMICAL SOC2019Photolabile coumarins with improved efficiency through azetidinyl substitution
Pablo Rivera Fuentes, Zacharias Thiel, Eric Vauthey
Azetidinyl substituents have been recently used to improve the fluorescence quantum yield of several classes of fluorophores. Herein, we demonstrate that other useful photochem. processes can be modulated using this strategy. In particular, we prepd. and m ...
