Optical-resolution photoacoustic microscopy (OR-PAM) is an emerging technology capable of imaging optical absorption contrasts in vivo with cellular resolution and sensitivity. Here, we provide a visualized instruction on the experimental protocols of OR-PAM, including system configuration, system alignment, typical in vivo experimental procedures, and functional imaging schemes.

Zaman, Pennsylvania State University, University Park, PA While the use of various chemicals in experimental research is essential, it is also important to safely store and maintain them as a part of the Environmental, Health and Safety (EHS) program. The properties of chemicals and their reactivity vary broadly and if chemicals are not managed, stored, and labeled properly, they can have harmful or even destructive consequences such as toxic fume...

Optical biosensors utilize light to detect the binding of a target molecule. These sensors can utilize a label molecule, which produces a measurable signal such as fluorescence, or these sensors can be label-free and use the changes in optical properties, such as refractive index, to sense for the binding of the target molecule. This video introduces both label and label-free optical biosensors, demonstrates their use in the laboratory, and shows some applications of the technology.
FAQs
Refractive-index mismatch changes how light travels across boundaries between a specimen, surrounding material, and imaging system. These differences can increase light scattering or distort the path of transmitted light, making structures harder to observe accurately. Matching refractive properties helps preserve image clarity and supports more reliable measurements across interfaces.
Scattering redirects light, while absorption reduces the light continuing through the sample. Together, they can lower image clarity and interfere with observation, especially when researchers examine thicker specimens. Assessing both properties helps explain weak or uneven signals and guides choices that improve visibility of internal biological structures.
Transparency indicates that light can pass through a material, but it does not by itself ensure accurate imaging. Optical compatibility also depends on refractive-index relationships, scattering, absorption, and fluorescence behavior. A material may transmit light yet still create artifacts or reduce measurement reliability if its optical properties do not work well with the specimen and imaging system.
Researchers can consider the specimen, surrounding materials, and imaging system together rather than judging any component in isolation. They assess transparency, refractive-index matching, scattering, absorption, and fluorescence, then select conditions that preserve the desired signal. This evaluation can reduce artifacts and improve the consistency of observations and measurements.
It is particularly useful when researchers need to reveal structures within thick specimens, where light may be scattered or absorbed before reaching the imaging system. Improving the relationship among the sample, materials, and optics can increase signal quality and make internal organization easier to observe than under poorly matched conditions.
In live-cell imaging, it can help preserve image quality while cellular organization is observed. In histology, compatible optical conditions support clearer examination of tissue structure. For fluorescent labeling, they help maintain detectable fluorescence and reduce imaging artifacts. These benefits allow researchers to assess organization, development, and disease-related changes more reliably.
