As a outcome, the PA sign will increase with the absorbed energy and signifies the optical absorption of a sample. In addition, the PA imaging has deeper penetration due to the ultrasound transmission and sensitive detection, compared with limited gentle penetration in optical imaging . Taken collectively, the PA approach has been very engaging to the analytical community and its integration with current diagnostic platforms (e.g., ELISA) is promising to maneuver from the laboratory analysis to…See More
