Additionally, the diphenylamine test did not reveal presence of nitrates in the NPs colloidal solution after the third stage of centrifugation (Figure 4(a)).
Thereafter a 1 cm long hollow-fibre membrane filled with toluene acceptor solvent (prespiked with the diphenylamine internal standard) fitted at the tip of the Hamilton[R] syringe was introduced carefully into the solution and the vial was tightly capped.
Visualization of the bands was achieved bydrying the TLC plate at 120 C for 1 hour after reacting the plate with a solution consisting of 5 ml of acetone, 0.1 ml of aniline, 0.1 g of diphenylamine and 0.75 ml of phosphoric acid (85%).
Silver and gold nanoparticles were synthesized from silver neodecanoate and gold (I) sodium thiosulfate, respectively,in presence of DPA-NDI-SH (where DPA= Diphenylamine) in a single reaction vessel.

From all the synthesized derivatives 27(a-j), the compound 27h containing morpholine moiety was found to be most active followed by the compound 27i with piperazine moiety and compound 27e with diphenylamine moiety [54].
DNA content in the supernatant was determined using the method of diphenylamine reaction and expressed as the amount of DNA mg/g of wet weight of bone tissue [13].
DNA was determined by treating the nucleic acid extract with diphenylamine reagent and the intensity of blue colour was measured at 600 nm.

Double base smokeless powders typically contain nitrocellulose, dibutyl phthalate, diphenylamine, ethyl centralite, waxes and other hydrocarbon-based additives (Western 2007).
In this method a protein precipitate of serum containing sialic acid will react with diphenylamine producing a purple colour, which is quantitatively measured on a spectrophotometer at 540 nm.
