CRISPR-Cas9 cleaves DNA microspheres to release drug for efficient thrombosis treatment
Abstract The drug delivery nanocarriers are widely employed in thrombolytic therapy. However, the off targeting and ineffective drug release of delivery vehicles make it difficult to targeted accumulation, effective diffusion, and penetration into thrombus tissue. Herein, we reported a biocompatible magnetic microsphere constructed via a programmable DNA rolling circle amplification (RCA) reaction integrated with iron oxide magnetic nanoparticles (Fe3O4 NPs). By combining ultrasound and photoacoustic imaging for di …
