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.

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.

Optical detection of ultrasound is impractical in many imaging scenarios because it often requires stable environmental conditions. We demonstrate an optical technique for ultrasound sensing in volatile environments with miniaturization and sensitivity levels appropriate for optoacoustic imaging in restrictive scenarios, e.g. intravascular applications.
FAQs
Each objective magnification changes the relationship between the eyepiece scale and the specimen image. Therefore, a calibration made at one objective cannot be assumed to apply at another. Users compare the eyepiece divisions with a stage micrometer under the selected objective, establishing the scale value needed to convert later readings into micrometers.
After calibration, the user counts the eyepiece-scale divisions spanning the specimen or structure and applies the calibrated value for one division. This converts an apparent microscope reading into a standard distance, such as micrometers. The resulting measurement can then be compared across biological specimens examined under the same calibrated conditions.
Consistent focus helps the observer identify the boundaries of a cell, tissue feature, or microorganism accurately on the microscope image. Using the same objective for calibration and observation also preserves the scale relationship established with the stage micrometer. These controls reduce measurement inconsistency when dimensions are recorded across specimens or cellular structures.
Begin by selecting the objective magnification to be used. Calibrate the eyepiece scale against a stage micrometer at that magnification. Then observe the biological specimen without changing the objective, maintain consistent focus, count the relevant scale divisions, and convert them using the calibration value. This yields a measurement in micrometers or another standard unit.
Measurements from this technique can quantify cell dimensions, tissue features, microorganism size, and other microscopic distances. That makes it useful across cell biology, microbiology, and histology, as well as in teaching laboratories. By turning visual observations into standard units, it supports quantitative microscopy rather than relying only on descriptive impressions.
An optic micrometer application is especially valuable when a biological investigation depends on the dimensions of structures visible through the microscope. Cell biologists may measure cells, microbiologists may determine microorganism size, and histologists may assess tissue features. The shared measurement approach supports comparable dimensional records within each properly calibrated observation.
