Researchers have developed a chip capable of simulating a
tumor's "microenvironment" and plan to use the new system to test the
effectiveness of nanoparticles and drugs that target cancer.
The new system, called a tumor-microenvironment-on-chip
(T-MOC) device, will allow researchers to study the complex environment
surrounding tumors and the barriers that prevent the targeted delivery of
therapeutic agents, said Bumsoo Han, a Purdue University associate professor of
mechanical engineering.
