Sensing of iron(III)-biomolecules by surfactant-free fluorescent copper nanoclusters
Sensing and Bio-Sensing Research, 2019 Surfactant-free copper nanoclusters (sf-CuNCs) synthesized in the absence of external stabilizer, could be promising fluorescence biosensors because of the presence of relatively exposed surfaces that may ease coupling with biomolecules.

Advanced Functional Materials, EarlyView.Molecular rotors are fluorescent molecules that are sensitive to viscosity and temperature variations in the environment. They exhibit a direct correlation between fluorescence and viscosity within Newtonian fluids. However, this correlation becomes less straightforward in complex systems.
