Characterization of In Vitro Ovarian Tissue Fluorescence with Multiphoton Microscopy

Frontiers in Optics, 2005
The distribution of endogenous fluorescence in the ovary provides diagnostically useful information and aids in discriminating between normal and diseased tissue. Optically sliced, viable tissue provided correlative data for a clinical spectroscopic instrument.

Physical and biological limitations of in vivo multiphoton fluorescence microscopy

SPIE Proceedings, 2005
In this paper we present experimental and theoretical study of limitations on deep imaging of biological tissue structure using multiphoton fluorescence microscopy (MFM), that are imposed by scattering of short NIR pulses in optically turbid medium. The time stretching of the laser pulse and its transversal widening limit the maximum imaging depth of ...

Investigation of depilatory mechanism by use of multiphoton fluorescent microscopy

Confocal, Multiphoton, and Nonlinear Microscopic Imaging III, 2007
Transdermal drug delivery provides a non-invasive route of drug administration, and can be a alternative method to oral delivery and injection. The stratum corneum (SC) of skin acts as the main barrier to transdermal drug delivery.

Image Formation in Multiphoton Fluorescence Microscopy∗

1998
Abstract This chapter is dedicated to image formation in multiphoton fluorescence microscopy. In particular, the comparison of image formation is based on the three-dimensional intensity point spread function (IPSF), the three-dimensional optical transfer function (OTF), and axial and transverse image resolution for thin and thick ...

Improved laser scanning fluorescence microscopy by multiphoton excitation

2000
Publisher Summary The compound optical microscope has been central to countless advances in biological research. The growth of cell and molecular biology in recent years has forced the pace of microscopy research to provide high contrast images of increasingly more specific structures and functions in biological specimens.

In-vivo Multiphoton Excited Fluorescence Microscopy of the Spinal Cord

2018
Spinal cord disorders are frequent causes of morbidity and mortality in human and veterinary medicine alike. Despite spinal cord disease affecting nearly every vertebrate species on earth, the pathophysiological mechanisms of central nervous system (CNS) disease remain poorly understood, largely due to failure of traditional ex-vivo imaging methods to ...
