The literature on functionalized supramolecules like calix 4]pyrrole, calix 4]resorcinarene and their analytical applications has been comprehensively covered. Various synthetic techniques, mechanism and modifications have also been discussed. When macrocycles interact with other molecules by certain non-covalent interactions such as dipole-dipole, ion-dipole, hydrogen bonding etc, they are termed as supramolecules. This book deals with the comprehensive literature survey on supramolecular chemistry.

In this book, we report the bio synthesis of aqueous stable gold nanoparticles by using Ocimum sanctum leaf extract as both reducing and capping agents. The Ocimum sanctum leaf extract reduced gold nanoparticles (AuNps) were characterized by UV/Vis, particle size analyzer (PSA)and transmission electron mictroscopy (TEM. Additionally, AuNps have been investigated for its application as "Turn Off" fluorescent sensor for Hg II]. A concentration of Hg II] in the limit of 10 M to 10 mM can be detected based on fluorescence quenching of the AuNPs and it was also concluded from the spectroscopic...
