SAN ANTONIO — Aug.8, 2018 — Southwest Research Institute (SwRI) and The University of Texas at San Antonio (UTSA) are developing a 3D printed implant that, when injected in a patient’s body, could deliver a personalized dose of medicine to treat infections as well as ailments such as arthritis, cancer and AIDS. The project, led by Albert Zwiener of SwRI’s Chemistry and Chemical Engineering Division and Dr. Lyle Hood of UTSA’s College of Engineering, is supported by a $125,000 grant from the Connecting through Research Partnerships (Connect) program.
For a drug to be effective, patients must take a minimum amount, but not so much that it makes them ill or causes serious harm. As a result of those limitations, someone who needs frequent doses of a specific medicine either has to take a pill each day or visit a doctor for treatment. To remedy this, the SwRI-UTSA team is working to create an implantable device that can deliver a controlled, personalized dose of medicine over several weeks.
“The implant addresses a specific patient’s illness in addition to their medical history and other health issues,” Zwiener said. “We inject this non-invasive device into the body to deliver medicine over a
