(A) Schematic diagram of Raman detection of crystals. (B) The measured data were compared with the database of HORIBA and the crystals were calcium oxalate dihydrate. (C) Bright field image of a tissue section, the part of kidney tissues (I), the part of paraffin (II) and the part of calcium oxalate dihydrate crystals (III) (magnification 500×). (D) Raman spectral data corresponding to (C).
