We demonstrate the potential of using evanescent fields, instead of conventional propagating sound fields, to manipulate particles at micro or nano scale. We generate an evanescent acoustic Bessel beam in liquid above a thin, circular, asymmetrically excited plate. In the sub-MHz ultrasound domain, ...
corridor and two-dimensional open field environment with NIR light stimulation transcranially. Activation of CaMKIIα neurons in M2 by 808 nm laser resulted in an increase in the distance traveled, while activation of PV neurons by 980 nm laser resulted in a decrease in the distance traveled...
The IR function can become very peaked (i.e. containing discontinuities) in particular in the far field of the transducer. As a result, in order to evaluate the IR function numerically, high sampling frequencies are required increasing calculation time and making data handling more cumbersome. How...
and compared with ordinary ultrasound imaging, PA imaging has better tissue contrast, thus representing a complementary imaging modality27,28. More interestingly, PA imaging in the second near-infrared (NIR-II, 1000–1700 nm) window has been developed very recently. In particular, the spectral ...

The calculation formula of tumor volume is (l × w2)/2, where l = length and w = width. Tumor resection was performed when the volume reached ∼500 mm3. For evaluation of CD47-targeted optical molecular imaging-assisted tumor resection and NIR-PIT in vivo, mice were randomly divided ...
(40%) to water with GNTs led to further decrease the threshold to 0.9 mJ/cm2due to facilitating the bubble formation phenomena. Using an established calculation algorithm, the absorption cross-section of GNTs with the dimension of 11 nm×60 nm was estimated as 7.6×10−10cm2at 900 nm, ...
Compared with conventional fluorescence imaging, PA imaging has higher spatial resolution and deeper penetration depth as the scattering of acoustic waves in tissue is orders of magnitude weaker than that of light; and compared with ordinary ultrasound imaging, PA imaging has better tissue contrast, ...
3D acoustic wave field cloaking has been the subject of quite a few studies since the pioneering works of Refs15,16,17. Such systems are getting increasingly more refined as the detection methods become more sophisticated. Considerable attention has been recently paid to the cloaking systems that ...
