Miniaturized all-fiber photoacoustic spectrometer for intravascular gas detection rivals lab-based systemsInstead of using bulky resonant gas cells for acoustic amplification or large microphones for higher acoustic sensitivity like traditional PAS systems, the all-fiber photoacoustic spectrometer ...
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 ...
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 ...
