Probing Plasmons in Graphene by Resonance Energy Transfer

, 2011
We propose a novel method to probe electronic excitations in graphene by monitoring the fluorescence quenching of a semiconductor quantum dot (or a dye molecule) due to the resonance energy transfer to the graphene sheet.

CdTe Quantum Dots Modified with Cysteamine: A New Efficient Nanosensor for the Determination of Folic Acid

Sensors, 2019
In this paper, we report the synthesis, characterization, and application of a new fluorescent nanosensor based on water-soluble CdTe quantum dots (QDs) coated with cysteamine (CA) for the determination of folic acid (FA).

Very high water permeability in vasopressin-induced endocytic vesicles from toad urinary bladder. [PDF]

, 1989
The regulation of transepithelial water permeability in toad urinary bladder is believed to involve a cycling of endocytic vesicles containing water transporters between an intracellular compartment and the cell luminal membrane.

Effect of Halogen Ions on the Photocycle of Fluorescent Carbon Nanodots

C, 2019
Carbon dots (C-dots) are well-known for their strong sensitivity to the environment, which reflects on intensity and shape changes of their fluorescence, induced by various interacting ions and molecules in solution. Although these interactions have been
