a Size-selective catalysis based on a traditional molecular sieve. b Size-selective molecular recognition in the confined space of DNA molecular sieve using cavity-tunable DNA nanocage framework nucleic acids. Large molecules, such as nucleases, proteins and larger analogues, are prohibited from contacting with inner recognition sites, while small target molecules are able to enter the cavity for efficient molecular recognition.
