Not only does iodine can be applied in visualizing fingerprints, the similar protocol can be applied to cyanoacrylate fuming that forms white complex with the salt in figureprints. Similarly, silver nitrate, which reacts with the sodium chloride in the palmer sweat and forms complex, can be heated to fume and visualize fingerprint using similar protocol. Such complex needs to be visualize
