title: Comparison of wide-field/deconvolution and confocal microscopy in bioengineering. Interest of multi-photon microscopy in the study of articular cartilage.
abstract: The increase in lateral and spatial resolutions is one of the major targets of research and development in the field of optical microscopies applied to living tissue. The optical geometry of Confocal Laser Scanning Microscopy (CLSM) demonstrates its undeniable advantage on conventional fluorescence microscopy by segregating the planes outside the focussing plane. The methodological and technological advances of the last five years have been fast evolving, especially with regard to the optimisation of CLSM and deconvolution process. The limited analysis in thick tissue have given rise to the development of other techniques, multi-photon excitation microscopy in particular. In this paper, we have applied these techniques on major biological applications in bioengineering (endothelial cell, chondrocyte in 3D-culture, human cartilage) and discussed the technical limitations and perspectives.
