Photoacoustic technologies for visualizing tumors and searching for foreign objects in the blood stream

In our work, we present data on the development of tumors at different stages in an animal model with engrafted tumors and study the number of circulating tumor cells produced by the tumors. Since the second task requires minimally invasive analysis of large volumes of blood, the in vivo photoacoustic flow cytometry setup was developed. It can work with the flow of objects in a flow cell, the flow of blood in a large vessel of an animal, and the blood flow in large vessels of the human body.
