Influence of structural dynamics on cell uptake investigated with single-chain polymeric nanoparticles

Francesco Stellacci, Lixia Wei, Suiyang Liao, Arthur Eliot Bouchez

Most nanoparticles' parameters affect their interactions with cells. To date, all the parameters studied are basically static (e.g., size, shape, ligands, and charge). This is unfortunate, because proteins have struc-tural dynamics that most nanoparticles ...
