The role of xanthophylls in the supramolecular organization of the photosynthetic complex LHCII in lipid membranes studied by high-resolution imaging and nanospectroscopy

Giovanni Dietler, Serguei Sekatski, Jiangtao Zhou

The xanthophyll cycle is a regulatory mechanism operating in the photosynthetic apparatus of plants. It consists of the conversion of the xanthophyll pigment violaxanthin to zeaxanthin, and vice versa, in response to light intensity. According to the curre ...

Spectro-electrochemical toolbox for monitoring and controlling quinone-mediated redox-driven molecular gripping

Jovana Milic, Thomas Schneeberger

The control of molecular systems by electrical charge or light is a prerequisite for their application in nanoelectronics. Such potential has been uniquely exploited in quinone-based resorcin[4]arene cavitands that can act as molecular grippers, reversibly ...

Fixed DNA Molecule Arrays for High-Throughput Single DNA-Protein Interaction Studies

Vytautas Navikas

The DNA Curtains assay is a recently developed experimental platform for protein-DNA interaction studies at the single-molecule level that is based on anchoring and alignment of DNA fragments. The DNA Curtains so far have been made by using chromium barrie ...

Host-guest chemistry with water-soluble gold nanoparticle supraspheres

Francesco Stellacci, Benjamin Timothée Nicolas Le Ouay

The uptake of molecular guests, a hallmark of the supramolecular chemistry of cages and containers, has yet to be documented for soluble assemblies of metal nanoparticles. Here we demonstrate that gold nanoparticle-based supraspheres serve as a host for th ...

Engineering the self-assembly of diketopyrrolopyrrole-based molecular semiconductors via an aliphatic linker strategy

Kevin Sivula, Xavier Adrian Jeanbourquin, Nestor Guijarro Carratala, Xiaoyun Yu, Andrea Gasperini, Emilie Aude Marie Ripaud, Muhammad Aiman Bin Rahmanudin Hamdan

The solid-state self-assembly of molecular semiconductors is a key aspect for controlling the optoelectronic properties of organic electronic materials. Herein, we investigate the use of a flexible linker strategy to control the self-assembly of a solution ...

Microfluidic platforms for high-throughput mammalian cell printing, transfection, and dosage-dependent studies

Kristina Pan Woodruff

With the advent of high-throughput and genome-wide screening initiatives, there is a need for improved methods for cell-based assays. Current approaches require expensive equipment, rely on large-scale culturing formats not suited for small or rare sample ...

Total Synthesis of Fijiolide A via an Atropselective Paracyclophane Formation

Christoph Heinz

The natural product fijiolide A is a secondary metabolite isolated from a marine-derived actinomycete of the genus Nocardiopsis. It displays inhibitory activity against TNF-Î±-induced activation of NFÎºB, an important transcription factor and a potential t ...

Light absorption in 1D and 2D nanostructured organic semiconductors

Damien Rolland

Organic photovoltaics will be one of the corner stones in solving the increasing world's energy demand issue. For this reason, a better understanding of the detailed mechanisms involved in energy conversion in the employed nanostructured materials is still ...

Conductance Switching and Many-Valued Logic in Porphyrin Assemblies

Nicola Marzari

We investigate quantum interference in the transport properties of porphyrin-based molecular devices, and are able to develop a minimal but qualitatively accurate model of conductance based on the maximally localized Wannier functions of just the isolated ...

Precise Control of Intramolecular Charge-Transport: The Interplay of Distance and Conformational Effects

Jacques-Edouard Moser, Mateusz Barnaba Wielopolski, Lars-Hendrik Mewes

A new series of donor–bridge–acceptor (D–B–A) compounds consisting of π-conjugated oligofluorene (oFL) bridges between a ferrocene (Fc) electron-donor and a fullerene (C60) electron-acceptor have been synthesized. In addition to varying the length of the b ...
