Quizplus · Accepted Answer

Protein residues are best developed using ninhydrin. Ninhydrin reacts with amino acids present in proteins, creating a distinct purple color that can be visualized and photographed. Physical developer and iodine are typically used to develop latent prints, while dusting powder is used for visible prints. However, none of these methods are as effective at developing protein residues as ninhydrin.
