Abstract

One of the major obstacles in nanoparticle-based therapy is to achieve tumour targeting, limiting non-specific accumulation of the nanoparticles. Here the authors propose the conjugation of anti-HER2 scFv fragments to the silica nanoparticles, increasing specificity and limiting the final size of the immunoconjugates below the renal clearance threshold.
