The Systematic Targeting Of MicroPlastics (STOMP), a nationwide $144 million program to create the definitive toolbox for measuring, researching, and affordably removing microplastics and nanoplastics (MNPs) in the human body. The STOMP program will focus on three technical areas across two phases: measurement and mechanism (phase one), and removal (phase two). During the first phase, STOMP performers will design experiments to understand microplastics within the human body. They will also develop gold-standard microplastics measurement methods, including a clinical test that will quantify individual microplastic burden, thus making monitoring and intervention possible at scale. Removal is the focus in phase two and where the earlier work proves indispensable.

ARPA-H Impact:

From long appointment wait times to complex medication regimens, our healthcare system places burdens on patients at every turn. Our current care model means people spend less time in their communities and more time traveling to clinics. What if, instead of care that constantly disrupts daily life, technology could deliver care that works within it? With ARPA-H projects that push the state of the art of cell engineering and bioelectronics, Program Manager Paul E. Sheehan, Ph.D., envisions a convenient, affordable future of medicine where patients can receive critical health information and treatment through safe and secure devices that are worn, ingested, or implanted. Read our latest ARPA-H Impact Story to learn more about these patient-centered solutions—and watch how one such device may revolutionize cancer care.
