Multiphoton microscopy has rapidly gained popularity in biomedical imaging and materials
science because of its ability to provide three-dimensional images at high spatial and …

Application of two-photon microscopy (TPM) to translational and clinical cancer research
has burgeoned over the last several years, as several avenues of pre-clinical research have …

We highlight the recent progress in ultrafast dynamic microscopy that combines ultrafast
optical spectroscopy with microscopy approaches, focusing on the application transient …

The fate of melanin in the epidermis is of great interest due to its involvement in numerous
physiological and pathological processes in the skin. Melanin localization can be assessed …

In this work, we investigate the relationship between the complex hierarchical assembly
structure of eumelanin, its characteristic broad absorption band, and the highly unusual …

The melanin pigments eumelanin (EM) and pheomelanin (PM), which are dark brown to
black and yellow to reddish-brown, respectively, are widely found among vertebrates. They …

Transient absorption (TA) spectroscopy has been extensively used in the study of excited
state dynamics of various materials and molecules. The transition from TA spectroscopy to …

Capitalizing on endogenous hemoglobin contrast, photoacoustic-computed tomography
(PACT), a deep-tissue high-resolution imaging modality, has drawn increasing interest in …

This article reviews the state of the art of ultrafast transient absorption microscopy, discusses
current experimental concepts and highlights future challenges. The advantages of transient …

Excited state dynamics provides an intrinsic molecular contrast of samples examined. These
dynamics can be monitored by pump probe spectroscopy which measures the change in …
