Abstract Silica nanoparticles embedded with [Ru(bpy)₃]²⁺ were synthesized by inverse microemulsion method, which endowed the fingerprint developing reagent with excellent photoluminescence and high safety. Carboxyl modified silica nanoparticles were prepared by a two-step method using amino precursor and ammonolysis reaction. Sulfonic acid modified silica nanoparticles were prepared by a two-step method using sulfhydryl precursor and oxidation reaction. The two types of negatively charged silica nanoparticles were compared comprehensively. It indicated that the absorption peaks of [Ru(bpy)₃]²⁺ and dye-doped nanoparticles in UV-Vis region were 452.43 nm and 476.06 nm, respectively. The average particle sizes of carboxyl and sulfonic acid modified silica nanoparticles were approximately 40 nm, and the DLS particle sizes were 122.4 nm and 110.1 nm, respectively. The peak values of Zeta potential distribution were -33.16 mV and -34.99 mV, respectively. When dispersed into the solution, carboxyl and sulfonic acid modified silica nanoparticles presented different sensitivities to the pH value of suspension. The optimized conditions for latent fingerprint development by the two negatively charged nanoparticles were achieved through orthogonal design experiment, which included dilution ratio 1∶3, pH value 2.9 and developing time 5 min for carboxylic SiO₂, and dilution ratio 1∶5, pH value 3.5 and developing time 5 min for sulfonic SiO₂. The newly synthesized nanocomposites are highly efficient and safe when utilized for latent fingerprint developing.
