“It’s something they’ve been doing for the past 25 years; they’re comfortable with the diagnostic accuracy, and they’re somewhat hesitant to make a change.”

— I. Michael Leitman, MD, chief of general surgery at Beth Israel Medical Center in New York, explaining why doctors rely so heavily on breast biopsies, as reported by CBS News

Customized Molecular Probes Offer Better Tumor Visualization

A new class of nanoparticles for molecular imaging may eventually allow for the individualized targeting of tumors. According to investigators at Memorial Sloan-Kettering Cancer Center and Cornell University, these particles are biologically safe, stable, and small enough to be easily transported across the body’s structures and efficiently excreted in urine. It is the first time that all of these properties have been successfully engineered on a single-particle platform, called C dots, to optimize the biological behavior and imaging properties of nanoparticles for use in a wide array of biomedical and life science applications. The work was published in the January issue of Nano Letters.

“Highly sensitive and specific probes and molecular imaging strategies are critical to ensure the earliest possible detection of a tumor and timely response to treatment,” says the study’s senior author, Michelle S. Bradbury, MD, PhD, a physician-scientist specializing in molecular imaging and neuroradiology at Memorial Sloan-Kettering Cancer Center. “Our findings may now be translated to the investigation of tumor targeting and treatment in the clinic, with the goal of ultimately helping physicians to better tailor treatment to a patient’s individual tumor.”
