%X There are various methods available for the development of latent fingerprints on different substrates. This paper presents a new powder method for the development of latent fingerprints on different porous and non porous substrates. A fluorescent small particle reagent (SPR) based on zinc carbonate hydroxide monohydrate, also called basic zinc carbonate has been formulated. The other ingredients of the formulation are Rhodamine B dye and a commercial liquid detergent. The composition develops clear, sharp and detailed fingerprints on a large number of non-porous items, after these were immersed in water up to 96 hours. The raw materials used to prepare the SPR are cost-effective and non-hazardous. The novel formulation develops prints of a better quality as compared to the conventional, molybdenum (IV) sulfide-based composition. The fluorescent nature of the reagent helps enhance weak, fragmented and chance fingerprints that are often found at crime scenes
