Samuel Sia, a professor of biomedical engineering at New York City’s Columbia University, has developed a 3D printed biobot that can be implanted in the body to release controlled doses of drugs. The amazing device can be controlled from outside the body using only magnets.
For patients who have been diagnosed with cancer, treatment options are often few and far between, and in many serious cases, starting an intense course of chemotherapy becomes a necessity rather than a choice. But despite being a powerful weapon against cancer, chemotherapy takes its toll on the body in a number of ways: chronic pain, nausea, fatigue, hair loss, and the chance of infertility are just some of the adverse effects that chemotherapy can present. Fortunately, scientists are working hard to develop more effective ways of delivering chemotherapy drugs, including a new 3D printing method that involves fabricating squishy, “clockwork” micromachines that deliver precise drug doses from within the body.
