Development of photoacoustic imaging agent using self-assembling system

In photoacoustic imaging, it is possible to perform deep tissue imaging in living organisms and obtain cross-sectional images. Moreover, when paired with conventional ultrasound images, morphological information can be derived simultaneously with functional information by using an imaging agent. Similar to fluorescence imaging, photoacoustic imaging agents, if designed appropriately, will likely lead to the development of a wide range of specific biomolecules and agents that recognize the environment. In this study, we aim to develop a photoacoustic imaging agent that can detect specific disease states and molecules, by allowing it to form a self-assembling system efficiently, thereby changing the photoacoustic spectrum.
