Abstract:

Deoxyribozymes(DNAzymes) are synthetic deoxynucleotide oligomers with enzyme-like activities identified through in vitro SELEX selection technology. DNAzymes have been widely explored in a broad range of applications, notably in biosensing and biomedical devices, owing to their easy synthesis and modification, stable chemical structure and excellent catalytic activity. Regulating the activity of DNAzymes is the key for exploring its potential utilization in many fields, and the flexible control will dramatically promote the application of DNAzymes. In this review, we summarize some methods for the regulation of DNAzymes activity and introduce their main applications in biomedical analysis. It is believed that DNAzymes will play a critical role in chemistry and medicine in the future.

Key words: Deoxyribozyme, Activity regulation, Biosensing, Medical diagnosis
