They also leveraged quartz-enhanced photoacoustic spectroscopy (QEPAS ... the new method using the laser developed by Stuttgart Instruments and a commercially available QEPAS gas cell to analyze ...

A team at South Korea's Pohang University of Science and Technology (POSTECH) has developed a way to process low-resolution label-free photoacoustic images into high-resolution virtually stained ...

However, it requires fluorescent staining, which poses risks of photobleaching and phototoxicity, potentially damaging the cells under study. Conversely, mid-infrared photoacoustic microscopy (MIR-PAM ...

Conversely, mid-infrared photoacoustic microscopy (MIR-PAM) allows for label-free imaging, preserving cell integrity. Yet, its reliance on longer wavelengths limits spatial resolution, making it ...
