英文摘要：

Due to its advantages,including high catalytic efficiency,good recognition ability,mild reaction condition and good biocompatibility,enzyme-assisted bioanalysis has been widely used in the detection of biomolecules.However,the application of routine methods is always limited by the complex matrices and the trace amound of target.Therefore,it is getting more and more important to develop ultra-sensitive detection methods based on the signal amplification.This review presents the fundamental introduction of enzyme and the enzyme-assisted signal amplification for biomolecule detection.Furthermore the future trends and potential of enzyme are outlined.
