Article Abstract

The development of DNA delivery techniques is critical to promote the wider use of deoxyribonucleic acids as cellular transporters. The present study aimed to develop a type of DNA nanoparticle (citZ-box) to automatically load and release cargo. The restriction enzyme can cleave citZ-boxes at pro-designed sites, and the enhanced green fluorescent protein gene (eGFP) can be delivered into the B. subtilis protoplasts by them. The process of eGFP expression is recorded using a confocal microscope over 4 h. Here, multiscaffold and multimodular designs are used for citZ-box assembly with a DAEDALUS module, DX_cage_design and rem (edge_length, 21), to ensure the structure was predicted as B-type DNA. Finally the citZ-box is estimated to be a 50.7 nm cube. The 3D structure of the citZ-box particle is detected to be approximately 50.3 ± 0.3 nm. DNA nanoparticles prepared as citZ-boxes have great potential as drug carriers with automatic loading and releasing abilities.
