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 ...
Valorisation of Mixtures of Linear Alkenes using Cobalt-Mediated Isomerisation and Hydroformylation Chemistries
<p>Active catalysts derived from cobalt and the Xantphos ligand were synthesised, characterised and tested in the</p><p>hydroformylation of pure linear alkenes or their mixtures. The preformed complex [Co2(CO)6(Xantphos)] ...
Extracellular Vesicles Derived from Plasmodium-infected and Non-infected Red Blood Cells as Targeted Drug Delivery Vehicles
Among several factors behind drug resistance evolution in malaria is the challenge of administering overall doses that are not toxic for the patient but that, locally, are sufficiently high to rapidly kill the parasites. ...
Aproximacions a la perspectiva de la persona en tractament de manteniment amb metadona: Reflexions a propòsit de 10 anys de recerca
Els tractaments de manteniment amb metadona (TMM) són un autèntic tractament psicofarmacològic de la dependència d'heroïna i, a la vegada, un element indispensable de les polítiques i les intervencions de reducció de danys. ...
Development of DNA Aptamers Against <i>Plasmodium falciparum</i> Blood Stages Using Cell-Systematic Evolution of Ligands by EXponential Enrichment.
"New biomarkers have to be developed in order to increase the performance of current antigen-based malaria rapid diagnosis. Antibody production often involves the use of laboratory animals and is time-consuming and costly, ...
Manufacturing and properties characterization of Ti patterned coatings for water electrolyzers by CSAM
This work investigates the microstructure and manufacturing control of the masked Cold Spray Additive Manufacturing (CSAM) strategy for producing of new bipolar plates (BPPs) for Proton Exchange Membrane (PEM) electrolyzers, ...
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, ...
Mono- and Dinuclear Gold(I) Coumarin Complexes: Luminescence Studies and Singlet Oxygen Production
The 4-(thiolmethyl)-7-(diethylamino)-2H-chromen-2-one ligand has been synthesized and used as chromophore in several mono- and dinuclear gold(I) compounds that contain a phosphane at the second coordination position. Four ...
Exploring optimal graphene slit-pore width for the physical separation of water-methanol mixture
Efficient and sustainable techniques for separating water- alcohol mixtures are in high demand in the industry. Recent research has revealed that nanotechnology could be the optimal solution. In this study, we investigate ...
Comparative study of ex vivo transmucosal permeation of Pioglitazone nanoparticles for the treatment of Alzheimer's disease
Pioglitazone has been reported in the literature to have a substantial role in the improvement of overall cognition in a mouse model. With this in mind, the aim of this study was to determine the most efficacious route for ...
On the uptake of cationic liposomes by cells: from changes in elasticity to internalization
