Sources, Mechanisms and Toxicity of Nanomaterials in Plants

Dr. Jose R. Peralta-Videa is an Adjunct Professor in the Department of Chemistry and the Engineering PhD program. He earned a Doctor in Science degree from the Genetic Center in the Postgraduate College at Chapingo, Mexico in 1986 and a Ph.D. in Environmental Science and Engineering from The University of Texas at El Paso in 2002. His current research is focused in the area of nanotoxicology, with an emphasis on the toxicity of nanoparticles in terrestrial systems. He has published more than 150 referred articles, 10 book chapters, and 4 manuals/booklets. As Senior Research Associate of Dr. Gardea-Torresdey, Chair of Chemistry Department, Dr. Peralta-Videa is active member of the University of California Center for Environmental Implications of Nanotechnology (UC CEIN). UTEP is the branch of UC CEIN responsible for investigating the interaction of nanoparticles with terrestrial plants. Dr. Singh obtained his PhD from the University of Allahabad on topic “Oxidative stress and antioxidant system in some cyanobacteria simultaneously exposed to UV-B and heavy metal.” He has authored 102 publications, as well as editorials in reputed journals. His area of research interest is the role of nitric oxide and hydrogen sulphide signalling in the regulation of abiotic stress in plants. Dr. Singh is also working as an editor and reviewer of several reputed international journals. Vijay Pratap Singh is an Assistant Professor, Department of Botany C.M.P. Post Graduate College, University of Allahabad, India. Dr. Singh has obtained his D.Phil. degree from University of Allahabad. He has authored 95 publications including book chapters and editorials in reputed journals. He has edited several books with Elsevier, Wiley, CRC Press, Nova Publisher, Studium Press, etc. His area of research interest is regulation of abiotic stress in plants with special emphasis on nitric oxide, hydrogen sulfide, reactive oxygen species and phytohormonal signaling. Dr. Singh is also working as an editor and reviewer of reputed international journals. Dr Tripathi has studied the effect of silica on physiological and biochemical responses such as photosynthesis, biotic and a-biotic stress, nutrient uptake as well as yield and quality of crop plants to stress factors such as metal, and the synchronized detoxification of harmful reactive oxygen species by their antioxidant defense mechanisms. He has also studied the interactions of physical Instruments like LIBS, EPMA and Florescence spectroscopy on stressed and non-stressed plants and get the information. His most recent research is moving towards gene level/protein level regulation of stress relieving mechanisms in organisms with and without the presence of silicon. He is on the editorial board for 6 different journals, and is a reviewer for a number of journals including two Elsevier journals: Plant Physiology and Biochemistry as well as Ecology and Environmental Safety Dr. Sangeeta Pandey is currently working as an Assistant Professor at Amity Institute of Organic Agriculture, Amity University Uttar Pradesh, Noida, India. She was awarded the Post-Doctoral Fellowship of the UGC, New Delhi. She is currently working on plant-growth promoting bacteria and nano-particles. She has published more than 25 papers in International journals and authored one book. She has also completed two projects granted by the government of India.
