TL;DR: It is shown that single-walled carbon nanotubes conjugated with cyclic Arg-Gly-Asp (RGD) peptides can be used as a contrast agent for photoacoustic imaging of tumours and intravenous administration showed eight times greater photoac acoustic signal in the tumour than mice injected with non-targeted nanot tubes.

TL;DR: Using a 2-D array of capacitive micromachined ultrasonic transducers (CMUTs) to perform 3-D photoacoustic and acoustic imaging using a tunable optical parametric oscillator laser system that generates nanosecond laser pulses was used to induce the photoac acoustic signals.

TL;DR: 3-D photoacoustic imaging of light absorbing objects embedded as deep as 5 cm inside strong optically scattering phantoms using a miniaturized CMUT array of 16 × 16 elements shows that CMUTs with integrated front-end amplifier circuits are an attractive choice for achieving relatively high depth sensitivity for PAI.

TL;DR: 3-D photoac acoustic imaging of optically absorbing targets embedded as deep as 5 cm inside a highly scattering background medium using a 2-D capacitive micromachined ultrasonic transducer (CMUT) array with a center frequency of 5.5 MHz makes the CMUT a promising technology for deep tissue photoacoustic imaging.

TL;DR: In this paper, a 2D capacitive micro-machined ultrasonic transducer (CMUT) array and associated electronics are used to measure and characterize the pressure fields of megasonic cleaners.
