Illuminating the invisible: using gold particles to map cancer in real-time
In short: Surgeons often struggle to identify the smallest traces of deadly tumors, where traditional methods fall short. A new approach from Stanford University uses remarkable imaging technology to light up cancer-seeking gold particles inside the body. This technique aims to provide a visual roadmap for complete tumor removal.
The challenge in treating cancer often lies in the limitations of traditional biochemical studies, which may fail to capture how biomolecules behave in living tissue. Adam de la Zerda, an Associate Professor of Structural Biology and Electrical Engineering at Stanford University, is addressing this by developing molecular imaging technologies. His work focuses on visualizing the complex behaviors of biomolecules—such as signaling factors and posttranslational modifications—as they change across different times, spaces, and local environments within a living subject.
One of the most promising applications of this research is the use of gold particles designed to seek out cancer cells. By injecting these particles into the body and using specialized imaging technology to illuminate them, de la Zerda's lab aims to provide a high-precision visual guide for surgeons. This could allow for the identification and removal of even the tiniest traces of tumors that might otherwise be missed, potentially preventing recurrence and improving patient outcomes.
The research is grounded in the intersection of engineering and structural biology. De la Zerda, who transitioned from an engineering background to structural biology, builds optical imaging instrumentation to study cancer and ophthalmic disease in animal models. By creating both chemical tools and imaging hardware, the de la Zerda Group seeks to bridge the gap between basic science and clinically translatable work. The goal is to reveal molecular mechanisms that are currently invisible, providing a foundation for entirely new diagnostic and therapeutic approaches.
