Abstract

DNA hydrogels exhibit unique properties such as sequence programmability

molecular recognition capability

stimuli-responsiveness

biocompatibility

and biodegradability

which have enabled their extensive applications in materials science and biomedical fields. Rolling circle amplification (RCA)

a simple and efficient isothermal enzymatic amplification strategy

can synthesize ultra-long single-stranded DNA with numerous repeated functional units. Leveraging RCA technology

researchers have developed a series of smart DNA hydrogel materials with promising potential for biomedical applications. This review summarizes the methodologies for fabricating multifunctional DNA hydrogels

via

RCA reaction

discusses the interactions between polyvalent aptamer-incorporated DNA hydrogels and biological particles upon specific recognition

and highlights their applications in the field of disease therapy and diagnosis.
