Anion Recognition

Anions are ubiquitous in biological systems that play significant roles in the wide areas of biology, pharmacy, and environmental science. The design of receptor systems for anion recognition has therefore developed into a key area of supramolecular chemistry, have received considerable attention due to their analytical applications. Among various anions of biological interest (halides, phosphates, sulphates etc.), considerable efforts have been devoted to detect and quantify phosphate anions. This is partly due to the important roles that anions play in biological systems (e.g. phosphorylated species) and the environment (e.g. cyanide and nitrate). However, the development of selective receptors for specific biological target in aqueous media is still a daunting task due to the high non-covalent affinity of water molecules with the substrates. Our aim is to develop novel chemical receptors for the efficient recognition of phosphorylated molecules of biological interest. During my Marie-Curie Fellowship at Imperial College London in Prof. Vilar's group, we reported a new strategy to design small molecule probes as MRI contrast agent using in vitro model testing (Chem. Commun., 2011, 47, 10245-1024)

We have studied the role of geometry or extent of receptor–anion interaction in the presence of anions on the Supramolecular gel network RSC Adv., 2016, 6, 83303–83311.

Anti-cancer Drugs

In collaboration with Prof. Helga M Ögmundsdóttir, we are developing anti-cancer drugs based on Tin complexes
