Quantitative Photoacoustic Imaging in the Acoustic Regime using SPIM
, 2017 While in standard photoacoustic imaging the propagation of sound waves is modeled by the standard wave equation, our approach is based on a generalized wave equation with variable sound speed and material density, respectively.

Advanced Science, EarlyView.This review introduces the concept of “general curvy surface reconstruction,” which incorporates both geometric and physical dimensions, representing an upgrade over conventional geometric reconstruction that focuses solely on spatial relationships. Particular emphasis is placed on the emerging opportunities enabled by advanced measurement techniques ...

Light source effects on aerosol photoacoustic spectroscopy measurements [PDF]
Journal of Quantitative Spectroscopy and Radiative Transfer, 2017 Photoacoustic spectroscopy measurements of flame-generated soot aerosol coated with small amounts of water yielded absorption enhancements that were dependent on the laser used: quasi-continuous wave (Q-CW, ≈ 650 ps pulse duration and 78 MHz repetition rate) versus continuous wave (CW).

Thermally Gated Dual‐Cascade Nanozyme for Enhanced Mild‐Temperature Photothermal Therapy
Advanced Science, EarlyView.A thermo‐responsive cascade nanozyme (Ru‐GOx‐PNN) synergistically enhances mild photothermal therapy by dual suppression of HSP70 through ROS‐induced lipid peroxidation and ATP depletion. This intelligent system effectively overcomes thermotolerance and amplifies apoptosis, offering a safe and precise strategy for tumor treatment.

Photoacoustics meets ultrasound: micro-Doppler photoacoustic effect and detection by ultrasound
, 2014 In recent years, photoacoustics has attracted intensive research for both anatomical and functional biomedical imaging. However, the physical interaction between photoacoustic generated endogenous waves and an exogenous ultrasound wave is a largely unexplored area.

Intelligent Soft Opto‐Magnetic Robot for Minimally Invasive Interventional Therapy
Advanced Science, EarlyView.An intelligent soft opto‐magnetic (iSOM) robot is developed that integrates remote magnetic actuation, skin‐mimic tactile perception, and photothermal ablation in a near‐millimeter‐scale design. It enables precise intraluminal navigation and localized ablation while providing real‐time optical feedback to support safe and accurate minimally invasive ...
