Biography

Suresh Kumar’s work is in the area of molecular assembly on nanomaterials and their analytical applications for molecular reorganization and assays. In his formative years, he prepared aniline with various substituents and used as colorimetric reagents for analysis of carbamate pesticides in environmental samples. He developed capillary and microchip electrophoresis techniques for rapid screening of polymerase chain reaction (PCR) products in various animals and plants. He also did his work is on synthesis of functionalized nanomaterials and quantum dots as matrices and affinity probes for the analysis of proteins and enrichment of peptides and proteins in matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS), atmospheric pressure matrixassisted laser desorption/ionization mass spectrometry (AP-MALDI-MS) and electrospray ionization mass spectrometry (ESI-MS). He developed NPs-based solvent microextraction techniques coupled with MALDI-MS for bioassays. He developed liquid nitrogen assisted spray ionization mass spectrometry for the identification of multiply charged proteins and amino acid clusters without electric field. These days he is working in the area of molecular assembly on nanomaterials surfaces and their analytical applications for colorimetric sensing of various chemical species (metal ions, pesticides, drugs, and biomolecules). A large part of his recent research is on the functionalization of nanoparticles with various organic derivatives and their applications in molecular reorganizations with bare eyes. His group developed several nanomaterials-based miniaturized UV-visible spectrometric techniques for the quantification of various molecules (metal ions, pesticides, drugs and biomolecules) those can be used for on-site monitoring of target analytes without any sample pretreatment. With growing environmental concerns regarding the usage of toxic chemicals, there has been a greater emphasis on development of greener technologies in the recent years. In this regard, Dr. Suresh Kumar’s research group is engaged in developing green chemistry approaches for preparation of carbon dots with high fluorescence quantum yield and used as fluorescent probes for imaging of biospecies (cells, bacteria and fungus) and for drug deliver.
