WebDFO was first suggested as a latent fingermark development reagent by Pounds in 1990 [], and since then, modifications to the original DFO method have been investigated by various research groups in an attempt to stabilise the working solution and improve the fingermark ridge contrast produced by the technique.Masters et al.[] investigated the usage of DFO … WebWhen these two fingerprint reagents are used consecutively, more fingerprints are able to be identified. Because Oil Red O (ORO) targets lipids, the strategy is to add this reagent in the sequence of DFO and NIN used consecutively to enhance previously undetected latent prints on dry, porous surfaces (e.g., paper). csn demographics

WebThe aim of this work was then to evaluate and to compare the effectiveness of three solutions of 1,2-IND in different formulations and a DFO solution employed as single enhancing treatments, in order to assess whether it was possible to replace a reagent with the other obtaining equally satisfying results. WebOther chemical methods to stabilize the fingerprints proved unsuccessful. Comparisons of the performance of 1,2-indandione with DFO in CFC113 performed on a limited range of substrates indicated that the reagent might be an effective method for the development of latent fingerprints despite the new reagent producing less intense fluorescence. WebNov 1, 2004 · 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 ... eagle tented lodge \u0026 spa
