“…Frequently, they are silver or gold nanoparticles on a dielectric substrate. Additionally, laser ablation of copper [141], silver [142], or gold [143] in solution forms a colloidal, SERS-active solution, and has been used to detect ANTA, FOX-7, and TNT.…”

“…They successfully separated and characterized DNB and 2,4-DNT. Jamil et al [143] used a colloidal solution of gold nanoparticles with cysteamine in solution to increase selectivity. The cysteamine and TNT formed a Meisenheimer complex, which was then spontaneously assembled onto the gold nanoparticles and could be detected by SERS.…”

“…AHT:TNT complex was prepared similar to the reported procedure for other primary amines and TNT [29,44]. Briefly, AHT stock solution (2 × 10 −4 M) was prepared in MilliQ water and the pH is adjusted to 8.5.…”

“…A wide range of primary amines has been used for TNT recognition since primary amines effectively form Meisenheimer complexes with this nitro aromatic compound. For example, cysteine [25,26], aminothiophenol [1,27], BSA [28] and cysteamine [29,30] have been used as selective TNT recognition molecules. In the present work, we have chosen 6-aminohexanethiol (AHT) as a potential selective TNT recognition molecule.…”
