文摘
- •
PEIQ, fluorescent Zn2 + probe, is synthesized by grafting PEI with quinoline derivatives.
- •
PEIQ exhibits high sensitivity and selectivity in absolute aqueous solution.
- •
PEIQ is biocompatible, water soluble, and cell-membrane permeable.
- •
Elementary logic operations have been demonstrated for PEIQ/Zn2 +/EDTA system.
- •
The practical application of PEIQ in living cell imaging is demonstrated.
