Concave Microwell Array-mediated Three-dimensional Tumor Model for Screening Anticancer Drug-loaded Nanoparticles

From The Clinical Editor: The battle against cancer is a big challenge. With new anti-cancer drugs being developed under the nanotechnology platform, there is a need to have a consistent and reliable testing system that mimics the in-vivo tumor scenario. The authors successfully designed a 3D tumor model using concave microwells to produce different tumor diameters. This will be of value for future drug screening.
