Fine Tuning of the Photoacoustic Generation Efficiency by Aggregation-Caused Quenching and Excitation Energy Transfer in Bodipy-Labeled Polylactide Nanoparticles

The relationship between the fluorescence decrease by aggregation-caused quenching (ACQ) and the photoacoustic generation efficiency in polylactide-Bodipy nanoparticles (PLA-Bodipy NPs) is demonstrated. PLA NPs with different PLA-Bodipy loadings …

Multi-approach strategy to probe the interactions between anions and new classes of molecular receptors

The anion distribution across cell membranes is a major element governing biological processes in the human body. This is ensured by ion channels, membrane proteins with the capacity to selectively regulate ion flows. Disruption of these…

Ultrabright two-photon excitable red-emissive fluorogenic probes for fast and wash-free bioorthogonal labelling in live cells

Fluorogenic bioorthogonal reactions are promising tools for tracking small molecules or biomolecules in living organisms. Two-photon excitation, by shifting absorption towards the red, significantly increases the signal-to-noise ratio and decreases…

Trace elements discriminate between tissues in highly weathered fossils

Palaeontologists assess the affinities of fossils using either morphology-based phylogenetic analyses, possibly enhanced by the use of advanced imaging techniques, or the identification of remnants or derivatives of fossil organic molecules with…

Light‐Promoted Basic Nitrogen Unmasking in Arene Ruthenium Complexes Derived from Z ‐Configured 2,2′‐Azobispyridine

Two novel 2,2′‐azobispyridine derivatives bearing N ‐dialkylamino substituents at position 4,4′ were synthesized and their E – Z photoswitching behavior was characterized by combination of 1 H‐ and 13 C NMR spectroscopy, UV–Vis absorption and DFT…

Revealing the Friction Stress of Microalgae in Microfluidic Devices through Mechanofluorochromism

Polydiacetylenes are deeply investigated for their mechanofluorochromic behavior: the blue, non-emitting solid phase, obtained by photopolymerization of the diacetylene precursor, is converted to the red, emitting one by a mechanical stimulus…

Evidence of artefacts made of giant sloth bones in central Brazil around the last glacial maximum

The peopling of the Americas and human interaction with the Pleistocene megafauna in South America remain hotly debated. The Santa Elina rock shelter in Central Brazil shows evidence of successive human settlements from around the last glacial…

Tuning the photoluminescence properties of SLE- and MRL-active tricarbonylrhenium(I) complexes through minor structural changes of the organic ligand

Solid-state luminescence properties depend on numerous parameters, including the molecular geometry and the intermolecular interactions that take place in the solid. To clarify the role played by these parameters on the photoluminescence (PL)…
