Opto acoustic and photoacoustic
WebPhotoacoustic targeting systems for intracellular recording. In one embodiment, the photoacoustic targeting system includes a light source, a micropipette electrode, an acoustic transducer, and a controller. The light source is configured to emit pulsed light. The micropipette electrode is configured to deliver the pulsed light to a target cell. Photoacoustic imaging or optoacoustic imaging is a biomedical imaging modality based on the photoacoustic effect. Non-ionizing laser pulses are delivered into biological tissues and part of the energy will be absorbed and converted into heat, leading to transient thermoelastic expansion and thus wideband (i.e. MHz) ultrasonic emission. The generated ultrasonic waves are d…
