New Chip (IMAGE) Purdue University Caption This illustration shows the design of a new chip capable of simulating a tumor's 'microenvironment' to test the effectiveness of nanoparticles and drugs that target cancer. The new system, called a tumor-microenvironment-on-chip device, will allow researchers to study the complex environment surrounding tumors and the barriers that prevent the targeted delivery of therapeutic agents.
