The most common reagents for fingerprint development on porous surfaces are ninhydrin and DFO. However, a large number of different reagent formulations are in use in fingerprint laboratories around the world. 1,2-Indanedione is also emerging as a potential reagent for the development of fingermarks on porous surfaces in routine casework. This situation prompted this study in which a survey was undertaken. The aims of the survey were two-fold: 1. Determine the type and frequency of use of fingerprint reagents applied to porous surfaces. 2. Determine the fingerprint community's awareness and experience with 1,2-indanedione. The fingerprint survey was sent to state police laboratories in Australia and New Zealand and to members of major fingerprint research groups and laboratories in the USA, UK, and Europe. Thirty-four responses were received from nine countries. These responses indicated a high degree of variability, in both the testing performed and the reagent formulations employed. Although only thirty-four agencies responded, some valuable insight into the lack of awareness and implementation of 1,2-indanedione is presented.
