Abstract

With the rapid development of biomedical imaging, non-invasive imaging method particularly has been widely used in clinical diagnosis. Different imaging methods have their own advantages, such as higher resolution of optical imaging, deeper penetration of acoustic imaging, high resolution photoacoustic imaging (PAI), and multi-parameter guidance of magnetic resonance imaging (MRI). Recent years, multimodal MRI, fluorescence imaging, PAI and others have been verified to play an important role in the field of molecular imaging and provided detail information for accurate in vivo diagnosis. Therefore, the design of multimodal probe that can integrate the above advantages to carry out combined imaging will be more accurate to assist diagnosis and treatment. While tumor microenvironment (TME) is highly critical in validating and optimizing current therapeutic strategies. Herein, we highlight the TME-triggered supramolecular system as an in situ nano-generator for multimodal imaging-guided treatment. The experimental protocols on the PAI/fluorescence imaging/MRI-based diagnosis are described in this chapter.
