Journal ArticleDOI
Light-Controlled Conductance Switching of Ordered Metal−Molecule−Metal Devices
Sense Jan van der Molen,Jianhui Liao,Tibor Kudernac,Jon S. Agustsson,Laetitia Bernard,Michel Calame,Bart J. van Wees,Ben L. Feringa,Christian Schönenberger +8 more
TL;DR: Reversible, light-controlled conductance switching of molecular devices based on photochromic diarylethene molecules, in which neighboring particles are bridged by switchable molecules, is demonstrated.
Journal ArticleDOI
Reversible Formation of Molecular Junctions in 2D Nanoparticle Arrays
TL;DR: In this article, the formation of the molecular junctions is reversible, making nanoparticle networks a promising platform for the development of molecular electronic circuits, and the flexibility of this approach lets us envisage the realization of more complex networks, for instance, by intermixing ensembles of bimodal nanoparticles of different materials.
Journal ArticleDOI
Silver nanoparticle toxicity and association with the alga Euglena gracilis
Xiaomei Li,Xiaomei Li,Kristin Schirmer,Kristin Schirmer,Kristin Schirmer,Laetitia Bernard,Laura Sigg,Laura Sigg,Smitha Pillai,Smitha Pillai,Renata Behra,Renata Behra +11 more
TL;DR: The impact of silver nanoparticles on aquatic algae has largely been studied with model species that possess a rigid cell wall, but the interactions of AgNPs with Euglena gracilis, a green alga having no cell wall but a pellicle, are explored.
Journal ArticleDOI
Spectroscopy of Molecular Junction Networks Obtained by Place Exchange in 2D Nanoparticle Arrays
Laetitia Bernard,Yavor Kamdzhilov,Michel Calame,Sense Jan van der Molen,Jianhui Liao,Christian Schönenberger +5 more
TL;DR: In this article, the insertion of conjugated molecular species within the nanoparticle arrays via spectroscopic and electrical transport measurements was studied, and it was shown that upon exchange of the alkanethiol chains with the conjugate oligomers, the conductance of the network increases by one to 3 orders of magnitude.
Journal ArticleDOI
Ultraviolet Plasmonic Chirality from Colloidal Aluminum Nanoparticles Exhibiting Charge‐Selective Protein Detection
Kevin M. McPeak,Christian D. van Engers,Christian D. van Engers,Sarah Bianchi,Aurelio A. Rossinelli,Lisa V. Poulikakos,Laetitia Bernard,Sven Herrmann,David Kim,Sven Burger,Mark Blome,Sriharsha V. Jayanti,David J. Norris +12 more
TL;DR: Chiral aluminum nanoparticles, dispersed in water, are prepared, which provide strong ultraviolet plasmonic circular dichroism, high-energy superchiral near-fields, and charge-selective protein detection.
