On the Application of Iodine Fuming Method to Present Sweat Latent Fingerprints

The iodine fuming method, due to its wide applicable scope, has always occupied an important position among various methods for developing latent fingerprints. However, the iodine fumed fingerprints are not easy to preserve, so how to simply fix the iodine fumed fingerprints becomes a big challenge for the police. This paper introduces two new methods to fix the iodine fumed fingerprints, namely, powder fixation method and solid glue fixation method. As the results show that, the powder fixation method is capable of rapidly and distinctly presenting the new and old sweat latent fingerprints on such porous and non-porous surfaces as newspaper, glass, alufer, adhesive tape, and so on; while the solid glue fixation method can obviously improve the quality of iodine fumed fingerprints after the coloration and fixation treatments.
