Abstract
A method for preparing a sample consisting of biological tissue in a solid matrix includes steps of: contacting the sample with a first compressed fluid stream wherein the matrix is soluble so as to extract the solid matrix, contacting the sample with a second compressed fluid, adapted to impregnate the tissue with an aqueous or water-soluble substance, evacuating the second compressed fluid gradually and in controlled manner, recovering the sample.
