Abstract Strain and temperature are important physiological parameters for health monitoring, providing access to the respiration state, movement of joints, inflammation processes. The challenge smart wearables is unambiguously discriminate strain using a single sensor element assuring high degree integration. Here, dual‐mode with two electrodes tubular mechanically heterogeneous structure enabling simultaneous sensing without cross‐talk reported. consists thermocouple coiled around an...
Photoacoustic (PA) imaging and tracking of stem cells plays an important role in the real-time assessment cell-based therapies. Nevertheless, limitations conventional inorganic PA contrast agents narrow range excitation wavelength first near-infrared (NIR-I) window hamper applications living subjects. Herein, we report design synthesis a second (NIR-II) absorptive organic semiconducting polymer (OSP)-based nanoprobe (OSPN+) for cells. Comparison studies biological tissue show that NIR-II...
Micro/nanorobots have long been expected to reach all parts of the human body through blood vessels for medical treatment or surgery. However, in current stage, it is still challenging drive a microrobot viscous media at high speed and difficult observe shape position single once enters bloodstream. Here, we propose new micro-rocket robot an all-optic driving imaging system that can actuate track with microscale resolution. To achieve force, engineer rocket-like triple-tube structure. Owing...
Precise diagnosis and effective treatment of gliomas still remain a huge challenge. Photoacoustic-guided photothermal therapy (PTT) has unique advantages over conventional techniques for brain tumor theranostics, but existing nanoagents photoacoustic imaging (PAI)-guided PTT are mainly organic small molecules or inorganic nanoparticles, which have the limitations poor photostability biocompatibility. Besides, restricted absorption in first near-infrared window (NIR-I) most compromises their...
Optical-resolution photoacoustic microscopy (OR-PAM) has been developed for anatomical, functional, and molecular imaging but usually requires multiple scanning different contrasts. We present five-wavelength OR-PAM simultaneous of hemoglobin concentration, oxygen saturation, blood flow speed, lymphatic vessels in single raster scanning. develop a pulsed laser via stimulated Raman scattering. The five wavelengths, i.e., 532, 545, 558, 570, 620 / 640 nm, are temporally separated by several...
We present fast functional optical-resolution photoacoustic microscopy (OR-PAM) that can simultaneously image hemoglobin concentration, blood flow speed, and oxygen saturation with three-pulse excitation. To instantaneously determine the dual-pulse flowmetry is developed to speed from signal decay in sub-microseconds. Grueneisen relaxation effect compensated for calculation. The imaging validated phantom vivo experiments. results show be measured accurately sub-microseconds by comparing...
Optical-resolution photoacoustic microscopy (OR-PAM) of oxygen saturation (sO2) offers high-resolution functional information on living tissue. Limited by the availability high-speed multi-wavelength lasers, most OR-PAM systems use wavelengths around 532nm. Blood has high absorption coefficients in this spectrum, which may cause and induce systematic errors sO2 imaging. Here, we present nonlinear that compensates for We model at different ultrasonic bandwidths. To compensate saturation,...
