Graphene-based materials recently have become more interesting due to their unique high conductivity, chemical stability, optical property, and intrinsic flexibility. Graphene oxide (GO) is an oxidization of graphene which has properties of inexpensive, scalable, and good water-soluble compared to...

Our instrument mainly including a femtosecond laser (Tsunami, Spectra-Physics, USA),which has a pulse width of less than 100 fs and a repetition rate of 80 MHz.To overcome the group velocity dispersion of the femtosecond laser through the AOM and the objective, an prism pair was used...

Multiphoton excited (MPE) fluorescence microscopy has been extensively used for biological imaging. With superior features such as minimum invasiveness, low photobleaching, and deep penetration depth, multiphoton microscopy has proven to be particularly suitable for three-dimensional (3D) imaging...
