(1) Stimuli-Responsive DNA Microcapsules\uff1aWe develop a method to synthesize substrate-loaded DNA microcapsules acting as drug carriers and being unlocked by stimuli. The base pairing of nucleotides provides a means to assemble microcapsules by interlinking DNA layers via hybridization. By programming the base sequences of DNA, stimuli-responsive functionalities encoded in the DNA shell of microcapsules allow for the dissociation of microcapsules in the presence of appropriate triggers and for the release of drugs.<\/p>\n\n\n\n

(2) Nucleoapzymes\uff1aThe concept of nucleoapzymes is to improve the catalytic functions of nucleic acids and to develop versatile applications in DNA nanotechnology. The nucleoapzyme is a hybrid structure of nucleic acids by the conjugation of a substrate binding aptamer with a DNAzyme sequence to mimic a native enzyme with both a substrate binding site and an active site. We study the catalytic activity of nucleoapzymes with different orientation and distance between the aptamer and DNAzyme units and find their activities can be controlled by their configurations.<\/p>\n\n\n\n

(3) Biosensors\uff1aTo achieve a rapid and accurate detection of analytes, we develop various sensing platforms. Specifically, we utilize biomolecules (e.g., nucleic acids, antibodies) as recognition elements to bind analytes and introduce signal amplification mechanisms (e.g., nanozymes, enzyme cascades) to convert the analyte information to optical or electrical output signals.<\/p>\n\n\n\n
