Ma’am discussed how traditional methods include the use of phys-

         ical powders such as magnetic powders, organic powders, lumines-

         cent powders, thermoplastic powders, SPR (Small Particle Reagent),

         and so on Iodine fuming, cyanoacrylate fuming, ninhydrin methods,
         DFO (1,8-Diazafluoren-9-one), silver nitrate, amido black, and other

         chemical methods of latent print development were also mentioned

         by Ma’am. She then discussed non-traditional methods for develop-

         ing latent prints using common kitchen powders such as turmeric

         cocoa powder, henna powder vermilion, and cornstarch powder.




         Non-traditional methods include using a laser beam, poly ray, poly
         light, OmniprintTM 1000, and a dust lighting kit. Ma’am also dis-

         cussed recent advances in research in the development of latent prints

         using nanoparticles, human metabolites, spectroscopy: Raman spec-

         troscopy, IR (Infrared) spectroscopy, micro x-ray fluorescence, ToF-

         SIMS (Time-of-Flight Secondary Ion Mass Spectroscopy), immu-

         nolabeling methods, and bacterial profiles. Finally, the session was

         opened for questions, and each question was positively received, and
         appropriate answers were provided.
