Herein, a fluorescence and surface-enhanced Raman spectroscopy dual-mode system was designed for cholesterol detection based on self-assembled plasmonic nanojunctions mediated by the competition of rhodamine 6G (R6G) with β-cyclodextrin modified gold nanoparticles (HS-β-CD@Au). The R6G quenched HS-β-CD@Au due to resonance energy transfer effect. When introduced as competitive guest, in cavities displaced recover its fluorescence. Moreover, two can be linked one form more stable 2:1 complex,...
ATP and reactive oxygen species (ROS) are considered significant indicators of cell apoptosis. However, visualizing the interplay between apoptosis-related ROS is challenging. Herein, we developed a metal–organic framework (MOF)-based nanoprobe for an apoptosis assay using duplex imaging cellular ROS.
