Quartz-enhanced photoacoustic-photothermal spectroscopy for trace gas sensing

Optics Express, 2021
A trace gas detection technique of quartz-enhanced photoacoustic-photothermal spectroscopy (QEPA-PTS) is demonstrated. Different from quartz-enhanced photoacoustic spectroscopy (QEPAS) or quartz-enhanced photothermal spectroscopy (QEPTS), which detected only one single kind of signal, QEPA-PTS was realized by adding the photoacoustic and photothermal ...

Thermally Gated Dual‐Cascade Nanozyme for Enhanced Mild‐Temperature Photothermal Therapy

Advanced Science, Volume 13, Issue 18, 27 March 2026.
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.
