We describe how 4-dimensional in vivo biochemical analysis can be performed using photoacoustic contrast nanoagents that have been designed to probe both structural and chemical information in vivo, enabling noninvasive, real time, spatially resolved chemical imaging. Early chemical imaging of a patient's tumor can inform the decision of effective treatment, regarding choices of chemotherapy, radiation, or immunotherapy.
