Eine Reihe Legierungen sind bei Raumtemperatur flüssig und vereinen so die Eigenschaften von Metallen und Flüssigkeiten. Anders als das flüssige Metall Quecksilber sind sie ungiftig. Damit sind sie gut handhabbar und eignen sich beispielsweise für elektronische Bauteile.
Assays to analyze the degradation, lysis and leakage of vesicles are commonly utilized in biology and physical chemistry. Here we show the fluorescence lifetime-based sensing of the leakage of stimuli responsive PEG-b-PLA block copolymer vesicles. The time-resolved technique differentiates between the fluorophore molecules in the solvated state at high concentrations, and in the wall material and in the solvated state at low concentrations. The vesicle leakage occurs after an incubation period, which was detected by the change of the time correlated single photon counting decays.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
