While biopsies of cancerous tissue can provide insight into an appropriate course of treatment, cancer can evolve, develop resistance to therapies, and find new pathways for growth. Now, researchers in the laboratory of KI faculty member and David H. Koch Professor of Engineering Michael Cima have developed an implantable device, small enough to fit inside a biopsy needle, allowing doctors to monitor cancer in real time. The device wirelessly transmits biomarker data, allowing clinicians to easily and inexpensively receive critical feedback on whether a treatment is working or needs adjusting. Cima’s device was covered extensively in the press, including in Boston Magazine and on Boston.com.
