Research on organ-on-a-chip technology is being explored for its potential applications in cancer therapy, including early detection and treatment. The technology involves the use of microfluidic engineering to create immune-competent organs-on-chips, which can be used for drug screening and toxicology testing. The development of this technology may have significant implications for the field of cancer treatment and drug development, with some reports suggesting it could transform the way cancer is treated and drugs are tested.
