A versatile two-photon fluorescent probe for ratiometric imaging E. coliß-galactosidase in live cells and in vivo.

We have described the design, synthesis, spectroscopy and biological applications of NI-ßGal, a versatile fluorescent probe to detect E. coliß-galactosidase in live cells and mice sensitively and directly, which holds great promise for its application in biomedical research such as gene therapy for cancer in the future.
