Ultrafast subwavelength CVD-graphene nanoheater for the generation of broadband photoacoustic waves. [PDF]

Photoacoustics
Efficient operation of light-to-pressure transducers and flexible fabrication on demand are key factors for the use of photoacoustic devices in various biomedical disciplines. Graphene layers can be grown at wafer scale and transferred to any surface geometry, providing a versatile approach for the development of photoacoustic emitters with a large and

Ultrafast photoacoustic cavitation pumped by picosecond laser for high-efficient and long-term shockwave theranostics. [PDF]

Photoacoustics, 2023
Photoacoustic (PA) theranostics is a new emerging field that uniquely combines diagnosis and treatment in one modality. However, its current status is compromised by the indispensable dependence on nonreversible phase-change nanoprobes that provides one-time-only action.

Efficient ultrafast photoacoustic transduction on Tantalum thin films

Applied Physics A, 2023
AbstractNano-acoustic strain generation in thin metallic films via ultrafast laser excitation is widely used in material science, imaging and medical applications. Recently, it was shown that transition metals, such as titanium, exhibit enhanced photoacoustic transduction properties compared to noble metals, such as silver.

FPGA-based reconfigurable processor for ultrafast interlaced ultrasound and photoacoustic imaging [PDF]

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2012
In this paper, we report, to the best of our knowledge, a unique field-programmable gate array (FPGA)-based reconfigurable processor for real-time interlaced co-registered ultrasound and photoacoustic imaging and its application in imaging tumor dynamic response. The FPGA is used to control, acquire, store, delay-and-sum, and transfer the data for real-
