Rapid and selective detection of aluminum ion using 1,2,3-triazole-4,5-dicarboxylic acid-functionalized gold nanoparticle-based colorimetric sensor

Abstract

A colorimetric sensor based on TADA–AuNPs accompanied by a masking agent DPC was constructed, with which the rapid quantification of Al3+ can be realized by UV-vis spectroscopy or naked eye observation.

“…The structure solution was completed by direct methods using SHELXT [27] and refinement by fullmatrix least-squares methods on F 2 using SHELXL [28]. The phenyl group is disordered and was modeled with two components related via a ring twist of 19…”

“…They exhibit antimicrobial, anti-inflammatory, analgesic, antifungal, antitubercular, antiviral, anticancer, antiplatelet, antimalarial, anticonvulsant, cardioprotective, antihelmintic, antiprotozoal, antitrypanosomal, and antischistosomiasis properties [11][12][13]. Moreover, they can be used to create sensor materials that can detect fluoride ions, cyanide ions, heavy metals, and toxic gases [14][15][16][17][18][19].…”

“…Schiff base hydrazones have a variety of applications in analytical chemistry, including the selective extraction of certain transition metals and their use in spectroscopic determination [11,12]. Additionally, hydrazones are versatile compounds that can be used in the construction of sensor materials for detecting fluoride ions, cyanide ions, heavy metals, and poisonous fumes [13][14][15][16][17].…”
