Due to their unique features, nanomaterials have gained considerable attention in recent years for applications in biomedicine. In particular, stimuli-responsive nanoparticles have shown promising results as a novel treatment approach for cancer. These nanoparticles can – for instance – produce heat upon a triggering stimulus (i.e. light). Current challenges include accumulating effective amounts of these nanoparticles in the tumor and efficiently delivering a stimulus that will elevate the temperature and, eventually, destroy the tumor. This project aims at finding approaches for the targeting and subsequent treatment of cancer cells with nanoparticles.
