Abstract

Easily synthesizable amphiphilic probes have been designed for the detection of Al3+ exclusively at mesoscopic interfaces. The surface charge of the surfactant assemblies and the fluidity of the lipid aggregates show pronounced effects on the extent of Al3+ detection. Excellent sensitivity has been observed specifically in the presence of anionic surfactants and the lipid membranes with more sol-like characteristics. Moreover, a variation in the modes of Al3+ complexation is observed on shifting from one regioisomer to another. For instance, the para isomer exhibits a 1:2 stoichiometry with the Al3+ ion, while for the orthoisomer, it is a 1:1 interaction. Considering the excellent sensitivity of the probe molecule towards Al3+, the present system has been utilized for the estimation of soluble aluminum content in acidic soil samples as well as in pharmaceutical tablets. Low-cost paper strips are developed for rapid, on-site detection of Al3+ without involving advanced instruments or trained technicians. Finally, the bioimaging of Al3+ is achieved in cervical cancer (HeLa) cells.
