An electrogenerated chemiluminescence (ECL) probe is based on trititanium dicarbide two-dimensional (2D) metal carbide catalyzed luminol and a preparation method. The biosensor includes the probe and the electrode of the biosensor, wherein the probe includes the Ti.sub.3C.sub.2 MXenes nanosheets, a linker molecule and a bio-recognition molecule 1; the Ti.sub.3C.sub.2 MXenes nanosheets are linked with the linker molecule by electrostatic adsorption; the linker molecule is linked with the bio-recognition molecule 1 by an amide group, contains a primary or secondary amine group, and presents positive potential in water; the bio-recognition molecule 1 is a single-stranded DNA sequence 1 having a carboxyl group at the 5′ end, and a CD63 protein on exosomes is recognized by the single-stranded DNA sequence 1. It was found for the first time that Ti.sub.3C.sub.2 MXenes can improve the ECL signal of luminol, the Ti.sub.3C.sub.2 MXenes could be applicable to the ECL probe.
