Publication number: 20120183474Abstract: The present invention provides methods of detecting soluble amyloid ? using curcumin-derived near infrared (NIR) imaging probes. Upon interacting with soluble amyloid ?, these probes undergo a range of changes, qualifying them as “smart” probes. In addition, the invention provides methods of detecting soluble amyloid ? by positron emission tomography (PET), magnetic resonance imaging (MRI) and multimodal imaging based on the curcumin-derived NIR imaging probes and derivatives thereof.Type: ApplicationFiled: July 29, 2010Publication date: July 19, 2012Inventors: Chongzhao Ran, Anna Moore
