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 ...

A team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a high-sensitivity differential Helmholtz photoacoustic cell and successfully applied it to ...

Recently, Prof. GAO Xiaoming’s team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, developed a novel photoacoustic spectroscopy (PAS)-based sensor that enabled ...

Cellulose is a naturally abundant polymer of linear β-1-4-linked d-glucose units. It can be found in lower and higher plants, marine animals, algae, valonia, fungi, bacteria, invertebrates and even ...

In life sciences, confocal fluorescence microscopy (CFM) is widely regarded for producing high-resolution cellular images. However, it requires fluorescent staining, which poses risks of ...

We study the temperature dependence of the underlying mechanisms related to the signal strength and imaging depth in photoacoustic imaging. The presented theoretical and experimental results indicate ...

Wayne State University researchers are using photoacoustic imaging to observe brain activity and, in the process, discovering more about how it responds to different types of learning and experiences.

Optical-resolution photoacoustic microscopy: Maximum amplitude projection (MAP) images of the mouse-ear, close-up views of the regions in the green dashed boxes, and cross-sectional B-mode images of ...

Tumors are not just isolated clumps of abnormal cells, but are associated with more complex system known as the "tumor microenvironment" (TME). Over the past few years, research has revealed that the ...

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 ...
