Summary: Optical nanosensors based on single-wall carbon nanotubes are able to capture the dynamics of biochemical processes. A one-step phase separation approach has been developed to isolate monochiral (6,4)-SWCNTs from mixed SWCNT samples, enabling high-resolution imaging in the near-infrared spectrum using standard Si-based cameras. (6,4)-SWCNTs modified with (GT)(10)-ssDNA become highly sensitive to the neurotransmitter dopamine, allowing for fast and high-resolution imaging of dopamine release from cells.

Summary: This study developed a highly selective and sensitive squaraine dye (F-0) for detecting Cu2+. The addition of Cu2+ caused a significant decrease in absorption peak and a 170-fold fluorescence quenching, with a detection limit as low as 7.2 nmol/L. F-0 exhibited excellent water solubility and enabled naked eye detection of Cu2+. A paper strip pre-stained with F-0 solution changed color from blue to colorless upon addition of Cu2+. F-0 showed high specificity to Cu2+ and low cytotoxicity, allowing for the monitoring of Cu2+ in living cells and mice through fluorescence imaging. These results suggest the great potential of F-0 for more complex applications.
