Fig. 6From: Cancer nanotechnology: current status and perspectivesTumor heterogeneity and drug resistance are two major obstacles that conventional chemotherapy face. Nanotechnology can overcome these obstacles through multi-modal treatments and increase therapeutic efficacy while decreasing dosage by utilizing targeted delivery, stimuli-triggered release, and formulations to improve PK/PD profiles.
