The targeted intracellular delivery of cytochrome C protein to tumors using lipid-apolipoprotein nanoparticles.

abstract：:When developed as targeting ligands for the in vivo delivery of biomaterials to biological systems, RNA aptamers immediately face numerous obstacles, in particular nuclease degradation and post-selection 2' modification. This study aims to develop a novel class of highly stable, 2'-fully modified RNA aptamers that are...
