Growth regulators such as gibberellins, brassinolides and jasmonates cause major effects in the development of plants. In this work, we first examined their metal ion binding capabilities. In particular we studied the effect of metal ions such as gold, silver, platinum, cadmium and palladium. Further, we also synthesized amine conjugates of some of those growth regulators. It was observed that in some cases not only did they bind to the metal ions, but also efficiently formed nanoparticles biomimetically. Specifically gold and platinum ions showed highest affinity for binding to the growth regulators resulting in the formation of nanoparticles. The effect of concentration and temperature on the morphologies of the nanoparticles formed was studied. We explored the metal ion binding mechanism and the formation of coordination complexes involved in the formation of the nanoparticles. We also examined the capacity of the nanohybrids formed as catalysts for degradation of toxic aromatic compounds.
