Doxorubicin-loaded quaternary ammonium palmitoyl glycol chitosan polymeric nanoformulation: uptake by cells and organs

Purpose This study was aimed to develop doxorubicin-loaded quaternary ammonium palmitoyl glycol chitosan (DOX–GCPQ) nanoformulation that could enable DOX delivery and noninvasive monitoring of drug accumulation and biodistribution at tumor site utilizing self-florescent property of doxorubicin.
