Multi-scale molecular photoacoustic tomography of gene expression.
PLoS ONE, 2012 Photoacoustic tomography (PAT) is a molecular imaging technology. Unlike conventional reporter gene imaging, which is usually based on fluorescence, photoacoustic reporter gene imaging relies only on optical absorption. This work demonstrates several key

Single Element-Based Dual Focused Photoacoustic Microscopy
Photonics, 2015 We present a single element-based dual focused photoacoustic microscopy (PAM) that shows improved signal-to-noise ratio and lateral resolution compared to conventional single focused PAM in the out-of-focus region.

Advanced Science, EarlyView.Field‐driven active colloids are framed as distributed micromachines in which externally supplied power, sensing, and control regulate task‐relevant states. By closing the loop between particle behavior, imaging, computation, and electric or magnetic actuation, these systems can progress from programmable motion toward adaptive functional outcomes ...

SCANNING PHOTOACOUSTIC MICROSCOPY
Acta Physica Sinica, 1982 The principle, possible applications and prospects of the scanning photoacoustie microscopy are described briefly. The microscopy system presented herewith attains a resolution of about 4,5 μm. Some images of such samples as the interdigital transducer of surface acoustic wave, integrated circuit and in particular the subsurface structure of the ...
