Gobika Research Group

Nanochemistry and Natural products focused research group based at the College of Chemical Science, Institute of Chemistry Ceylon

Welcome to the Gobika Research Group!

Dr. Gobika’s research work spans from fundamental research in natural products to the synthesis of a wide range of nanoparticles and nanocomposites with specific interests in their functionalities.

Sri Lanka is a tropical country that is blessed with lots of Natural sources which has exceptional biological activities and distinctive pharmacological effects. Sri Lanka has been identified as a biodiversity hot spot. The bioactive natural products available in natural sources can therefore be effectively used as an alternative for synthetic products.

Our research is mainly focused on the isolation and characterization of novel biologically active natural products with diverse chemical structure, from various fruits and vegetables which are native to Sri Lanka. Bioactive fractions of these extracts will be subjected to bioassay-guided fractionations in order to isolate bioactive compounds. Further, we intend to develop novel value-added products from isolated bioactive compounds to potential health-promoting activities.

We are currently focused on green synthesis and characterization of transition metal and metal oxide nanoparticles.  Nanocomposites fabrication using these novel nanostructures is also the main research focus. The aim is to create new eco-friendly and cost-effective nanoparticles/nanocomposites with unique physio-chemical properties not available in any other systems. The processing parameters, structural features, and interfacial reaction that underpin the physical and mechanical properties of these nanoparticles/nanocomposites lie in this category. In particular, we explore novel applications that can be used in emerging technologies such as electronics, textiles, catalysis, fluorescence, or a new generation of highly efficient antioxidants and antimicrobials.

We are always on the lookout for interdisciplinary research collaborators to join the group. If you are interested, please get in touch directly at tgobika@ichemc.edu.lk.
