Imaging Agent Illuminates Cancer and Surrounding ‘Hijacked’ Cells

Facebook X LinkedIn Email
Scientists at Washington University School of Medicine have developed an imaging agent that can identify multiple types of tumors as well as the surrounding normal cells that the cancer uses as a shield against attempts to destroy it. “This unique imaging agent identifies cancer cells as well as other compromised cells surrounding the tumor,” professor Samuel Achilefu said. “Cancer transforms surrounding cells so that it can proliferate, spread to other parts of the body, and escape treatment. This imaging compound can detect cancer cells and their supporting cast, the...Read full article

    fluorescence
    Fluorescence is a type of luminescence, which is the emission of light by a substance that has absorbed light or other electromagnetic radiation. Specifically, fluorescence involves the absorption of light at one wavelength and the subsequent re-emission of light at a longer wavelength. The emitted light occurs almost instantaneously and ceases when the excitation light source is removed. Key characteristics of fluorescence include: Excitation and emission wavelengths: Fluorescent materials...
