Biomedical imaging modalities such as magnetic resonance imaging (MRI) have revolutionized the ability to detect and track the progress of many cancer types. However, the difficulty of obtaining detailed images of cancer cells buried deep within normal tissues has slowed the usefulness of imaging technology for improved, personalized cancer care.

An approach biomedical engineers are pursuing to overcome this limitation involves building nanoprobes that are designed to travel throughout the body, accumulate in cancer cells, and send a signal that illuminates the tumor.

NIBIB-supported researchers at Johns Hopkins University have developed a smart nanoprobe designed to infiltrate prostate tumors and send back a signal using an optical imaging technique known as Raman spectroscopy. The new probe, reported in Advanced Science, has the potential to determine tumor aggressiveness and could also enable sequential monitoring of tumors during therapy to quickly determine if a treatment strategy is working.
