The invention discloses an application of a composite fluorescent probe in imaging detection of live tumor cells. When the composite fluorescent probe is used in imaging detection of live tumor cells,in a waveband of 580 to 620 nm, the composite fluorescent probe generates prominent fluorescent signals in live tumor cells, and the composite fluorescent probe is a 3-(4-amino)-butyric acid-acenaphthopyrazine-8,9-dinitrile compounded titanium dioxide quantum dot. Titanium dioxide has a strong light absorbing performance, energy absorbed by titanium dioxide is transmitted to 3-(4-amino)-butyric acid-acenaphthopyrazine-8,9-dinitrile, the emitting strength of the quantum dot is enhanced, strong fluorescent signals are obtained, organic substances are gathered on titanium dioxide nano particles,the water solubility of the quantum dots is improved, and moreover, the fluorescent probe has a good performance on penetrating the cell membranes.
