An improved forensic specimen collector includes a collection matrix coated with a dissolvable coating composition. The coating composition covers the irregular surface of the matrix, filling in the holes and openings to prevent passage of collected material specimens into the interior of the matrix. This facilitates retention of the specimens on the outer surface of the matrix and release of all of the specimens for analysis. The specimens are separated from the surface of the collection matrix by contacting the matrix with a liquid solvent selected to dissolve the coating, thereby releasing the specimen into the solvent. The solvent is selected in accordance with its solubility characteristics to form either a suspension of the specimen in the solvent, or to dissolve the specimen into the solvent to form a solution.
