Title: All-optical photoacoustic imaging towards single-cell resolution deep-tissue calcium imaging for neurobiology

Abstract: Combining optical excitation and ultrasonic detection, photoacoustic imaging has emerged in the last decades as a very powerful technique to provide high resolution images of optically contrasted objects embedded deep inside biological tissue.

After presenting the basic principles of this modality, I will discuss the technological key points that remain to be addressed regarding the ultrasound detection systems and molecular probes, and will present the last techniques that we developed in our group to approach single-cell resolution for deep-tissue calcium imaging.
