A new method for real-time detection and identification of very low concentrations of gases adds coherent control to quartz-enhanced photoacoustic spectroscopy, which uses a quartz tuning fork to ...

Optical-resolution photoacoustic microscopy is an up-and-coming biomedical imaging technique for studying a broad range of diseases, such as cancer, diabetes and stroke. But its insufficient ...

Miniaturized spectroscopy systems that can detect trace concentrations at the parts-per-billion (ppb) level are of utmost importance in applications ranging from environmental monitoring and ...

Tumor cells have higher metabolic activity compared to healthy tissue and consequently consume a lot of glucose. Positron Emission Tomography (PET)—the current gold standard diagnostic ...

Photoacoustic microscopy (PAM) continues to make inroads into biomedical imaging, thanks to its potential for capillary-level or sub-cellular resolution at greater depths than traditional optical ...

The brain relies on real-time delivery of oxygen and nutrients through its microvasculature, which threads through neural tissue like electrical wires. While modern imaging technologies allow ...

Neuroscientists have sought to better understand brain function but lacked the capability to observe neuronal activity deep within the brain. Scientists have applied rational molecular engineering to ...

In the last decade, photoacoustic tomography has slowly emerged as a versatile, radiation-free imaging modality that bears great potentials for basic research and clinical diagnostic applications. Its ...

Researchers have developed a new method for quickly detecting and identifying very low concentrations of gases. The new approach, called coherently controlled quartz-enhanced photoacoustic ...
