Abstract: | We report for the first time, the pH tunable self-assembly of chicoric acid, an HIV-I integrase inhibitor, which displayed a remarkable tendency to self-assemble at room temperature into varying nano- and microstructures. Furthermore, those assemblies were then functionalised with gold (Au) nanoparticles. We then investigated the biocompatibility of the materials by conducting in vitro cell attachment and cytotoxicity studies using normal rat kidney cells. The studies revealed that the biomaterials were non-toxic and biocompatible, and showed considerable adhesion to the cells. These results suggest that the assemblies could potentially be used for a variety of applications, such as carriers for targeted drug delivery as well as optoelectronics and sensors. Furthermore, the formation of highly organised nano- and microstructures of medicinally significant phytohormones such as chicoric acid is of particular interest as it might help in further understanding the supramolecular assembly mechanism of higher organised biological structures for the development of building blocks for various device fabrications. |
