Microscopes are an important tool in biomedical research as it allows for detailed observation and imaging of tissues. Since biological materials are opaque by their nature, severe light scattering ...

Figure 1. Conceptual illustration of label-free, multiphoton photoacoustic microscope (LF-MP-PAM). Near-infrared femtosecond laser enable us to observe endogenous NAD(P)H of neurons in brain slice and ...

In the field of materials characterization, optical microscopy is one of the most commonly used imaging techniques. It is estimated that the diffraction limit of optical light is half of the ...

Carbon nanotubes are cylindrical nanostructures made by rolling up sheets of graphene. Graphene sheets are only a single atom thick and this gives this form of carbon many special properties. For ...
