Methods: The authors developed two novel dendrimerâ gold (Au) complex-based nanoparticles using twodifferent synthesis routes: complexation method (formulation A) and precipitation method (formulation B). Using a biomimetic cancer-on-a-chip model, the authors evaluated the possible cytotoxicity and internalization by colorectal cancer cells of dendrimerâ Au complex-based nanoparticles. Results: The results showed promising capabilities of these nanoparticles for selectively targeting cancer cells and delivering drugs, particularly for the formulation A nanoparticles. Conclusion: This work highlights the potential of dendrimerâ Au complex-based nanoparticles as a new strategy to improve the targeting of anticancer drugs.This work is financially supported by the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 952603 (http://sgabu.eu/).
