Dr. Suban K. Sahoo is an Associate Professor in the Department of Chemistry, Sardar Vallabhbhai National Institute of Technology (SVNIT), in India. He completed his PhD in Chemistry at Punjab Technical University (PTU) in 2008, and was Visiting Professor at the University of Cagliari, Italy, in 2009, and at Kyungpook National University, Daegu, South Korea, in 2019. Dr. Sahoo’s research interests include fluorescence studies of the model compounds, design and development of chemosensors, colorimetric and fluorescent sensors based on nanoparticles and quantum dots (QDs), supramolecular deep cavitand and recognition of small guest molecules, computational chemistry, molecular dynamic simulations and docking, complexation studies of the ligands with various metal ions both by potentiometric and spectrophotometric methods, and synthesis of multidentate ligands and metal complexes. Prof. M. Reza Hormozi-Nezhad is a Professor of Analytical Chemistry at the Department of Chemistry and Institute for Nanoscience and Nanotechnology (INST), at Sharif University of Technology, in Tehran, Iran. Prof. Hormozi-Nezhad’s research interests include sensors and biosensors based on metallic nanoparticles and novel nanomaterials, shape selective synthesis of metallic nanoparticles on semiconductors formed through electroless deposition, shape selective synthesis of Au-nanoparticles by wet chemical methods, evaluation of Au and Ag surface plasmon peak for determination of biological active compounds, investigating shape evolution mechanism of nanomaterials by analysis of spectrophotometric data, and synthesis of metallic nanostructures for surface enhanced Raman spectroscopy (SERS).
