Dichroism of coupled multipolar plasmonic modes in twisted triskelion stacks
We present a systematic investigation of the optical response to circularly polarized illumination in twisted stacked plasmonic nanostructures. The system consists in two identical, parallel gold triskelia, centrally aligned ...
Malaria quantitative POC testing using magnetic particles, a paper microfluidic device and a hand-held fluorescence reader
A point-of-care (POC) device is reported for highly sensitive and selective detection of Plasmodium falciparum lactate dehydrogenase (Pf-LDH), a biomarker of malaria infection, based on a single-step magneto-immunoassay, ...
Folate-Receptor-Targeted Gold Nanoparticles Bearing a DNA-Binding Anthraquinone
In recent years, anthraquinones have been widening their therapeutic opportunities given their numerous health benefits. The search for adequate delivery platforms to improve their pharmacokinetics leads us to propose ...
Reading QR Codes on challenging surfaces using thin-plate splines
In real world uses, QR Codes are printed or overlaid on top of complex surfaces, like cylindrical bottles or other daily objects with random topographies that pose big challenges to their readout with the conventional ...
Method for reducing specular reflections in Mueller matrix imaging
Mueller matrix polarimetry has emerged as a powerful tool for non-destructiveoptical analysis of biological tissues and bioorganic materials, offering detailed insights intopolarization-specific properties such as ...
Time-resolved solvation of alkali ions in superfluid helium nanodroplets: Theoretical simulationof a pump–probe study
The solvation process of an alkali ion (Na+, K+, Rb+, and Cs+) inside a superfluid 4He2000 nanodroplet is investigated theoretically using liquid 4He time-dependent density functional theory at zero temperature. We simulate ...
Confronting positions: para- vs. meta-functionalization in triindole for p-type air-stable OTFTs
The 5,10,15-trihexyl-10,15-dihydro-5H-diindolo[3,2-a:3′,2′-c]carbazole core, namely triindole, is well-known for its prominent hole-transporting properties and air stability. The functionalization of this core is also ...
C60 fullerene as an on-demand single photon source at room temperature
Single photon sources are fundamental for applications in quantum computing, secure communication, and sensing, as they enable the generation of individual photons and ensure strict control over photon number statistics. ...
Clustering, collision, and relaxation dynamics in pure and doped helium nanoclusters: Density- vs particle-based approaches
The clustering, collision, and relaxation dynamics of pristine and doped helium nanodroplets is theoretically investigated in cases of pickup and clustering of heliophilic argon, collision of heliophobic cesium atoms, and ...
Exudative versus nonexudative age-related macular d generation: physiopathology and treatment options
Age-related macular degeneration (AMD) is an eye disease typically associated with the aging and can be classified into two types—namely, the exudative and the nonexudative AMD. Currently available treatments for exudative ...
Spin Crossover-Assisted Modulation of Electron Transport in a Single-Crystal 3D Metal−Organic Framework
Molecule-based spin crossover (SCO) materials display likely one of the most spectacular switchable processes. The SCO involves reversible changes in their physicochemical properties (i.e. optical, magnetic, electronic, ...
Tandem Mn-I Exchange and Homocoupling Processes Mediated by a Synergistically Operative Lithium Manganate
Pairing lithium and manganese(II) to form lithium manganate [Li2Mn(CH2SiMe3)4] enables the efficient direct Mn-I exchange of aryliodides, affording transient (aryl)lithium manganate intermediates which in turn undergo ...
Effect of substituents on the 1O2 production and biological activity of (N^N^N)Pt(py) complexes
Twelve (N^N^N)platinum pyridyl complexes, (N^N^N)Pt(pyF), were synthesised and investigated for their singlet oxygen generation and potential biological activities. They exhibited 1IL and 1MLCT absorption transitions at ...
Direct evidence of a graded magnetic interface in bi-magnetic core/shell nanoparticles using electron magnetic circular dichroism (e-MCD).
nterfaces play a crucial role in composite magnetic materials and particularly in bimagnetic core/shell nanoparticles. However, resolving the microscopic magnetic structure of these nanoparticles is rather complex. Here, ...

Selective signalling of alcohols by a molecular lattice and mechanism of single-crystal-to-single-crystal transformations
Single-crystal-to-single-crystal (SCSC) transformations of molecular materials involving exchange of lattice molecules are becoming commonplace and very relevant in areas like chemical sensing or the pharmaceutical sector. ...
Microfluidic 3D platform to evaluate endothelial progenitor cell recruitment by bioactive materials
Most of the conventional in vitro models to test biomaterial-driven vascularization are too simplistic to recapitulate the complex interactions taking place in the actual cell microenvironment, which results in a poor ...
