Profile Summary 

Animesh Samanta received his B.Sc. (H) in Chemistry in 2005 from Vidyasagar University before he moved to study his Master Degree in Bio-Inorganic Chemistry in 2007 from IIT Madras. In 2012, he obtained his Ph.D. under the supervision of Prof. Young Tae Chang for his thesis in the field of Chemical biology especially organic and nanoparticle synthesis and its application in Fluorescence and SERS imaging from National University of Singapore (NUS). He did his first post-doctoral research at A*STAR Singapore for three and half years in the area of Bio-imaging and therapeutic study under the same guidance. Later for a year, he did his 2nd post-doctoral research in the field of Bio-medical engineering at NUS before joining as Ramanujan Fellow at CSIR-NIIST, Thiruvananthapuram in 2016.  In his independent research career for two and half years, he mainly focused for the synthesis of novel fluorescent probes that include pH, reactive carbon species (RCS) and reactive oxygen & nitrogen species (ROS/RNS) at subcellular level.  His research interests include the chemical synthesis for the development of new fluorescent probes and non-invasive optical imaging such as fluorescence imaging, SERS imaging and nanoparticle based multimodal optical imaging for the study of cancer and neurodegenerative diseases.

Research Interest

Chemical Biology: Organic Fluorophore Synthesis, Nanohybrids formulation, Bio-sensing, Bio-imaging, Diagnostics and Therapeutics.

Acquiring the fundamental knowledges from core disciplines of Organic, Inorganic and Biology, our laboratory pursues reactivity-based sensing approach for the development of biosensors and bio-imaging probes. These probes are mainly small molecule or nanohybrid based luminescence probes and Surface Enhanced Raman Scattering (SERS) probes. These chemical probes are capable to study the imbalance of bio-analytes including pH, reactive carbon species (RCS), reactive oxygen & nitrogen species (ROS/RNS/RCS) at subcellular level leading to diagnosis of oxidative stress in the kidney, liver  and Arthritis and cancer. Major focus on "ratiometric" "On/Off" probes for heat shock, mitophagy, autophagy monitoring in cells. Key approaches both comprises of "target oriented synthesis for activity based probes and Diversity oriented synthesis followed by screening for unknown targets. In addition, multimodal therapeutic platform including photodynamic, chemo, radical, thermal and gene therapy for the treatment of cancer is the key interest of our research.
