Anurag Kumar Singh, PhD, is a Research Associate in the Department of Pharmaceutical Engineering and Technology at the Indian Institute of Technology (Banaras Hindu University), Varanasi, India. His research focuses on developing nanoparticulate systems for chronic pain, neurodegenerative disorders, brain-targeted drug delivery, diagnostics, and therapy. His work includes dendrimers, nanoporous silica and silicon materials, and polymeric nanoparticles for controlled drug delivery, with broader interests in nanomedicines for biomedical and healthcare applications and in integrating engineering, pharmaceutical, and medical research. He previously held postdoctoral research positions in cancer biology at Alabama State University, USA, and in nanotechnology and advanced materials at Bar-Ilan University, Israel. Vivek Kumar Chaturvedi, PhD, is a researcher supported by the Department of Health Research, Ministry of Health and Family Welfare, at the Institute of Medical Sciences, Banaras Hindu University, Varanasi, India. His research focuses on drug delivery, tissue engineering, and the synthesis, functionalisation, and fabrication of bio-nanomaterials for biosensor development. He previously conducted postdoctoral research in the Department of Gastroenterology at the Institute of Medical Sciences, Banaras Hindu University. He also contributes to scholarly publishing through peer review and the preparation of academic articles, books, and book chapters. Santosh Kumar Singh, PhD, is a Senior Scientist at the Centre of Experimental Medicine and Surgery, Institute of Medical Sciences, Banaras Hindu University, Varanasi, India. He has more than 25 years of research experience and has led projects supported by the Department of Science and Technology, Department of Biotechnology, and Science and Engineering Research Board. His academic activities include supervising doctoral and postdoctoral researchers and medical trainees across MD, MS, DM, and MCh programmes. He previously conducted postdoctoral research at Banaras Hindu University and served as a Visiting Scientist at the Institute of Physical Biology, University of South Bohemia, Czech Republic. He also contributes to scholarly publishing through service on the editorial boards of scientific journals. Jay Singh, PhD, is an Assistant Professor in the Department of Chemistry, Institute of Science, Banaras Hindu University, India. His research focuses on the chemical and biological synthesis of nanomaterials and the development of nanobiocomposites, conducting polymers, and self-assembled monolayers for sensor and biosensor applications. He develops enzyme-, antibody-, and DNA-based platforms for detecting clinically relevant bioanalytes, pathogens, pesticides, toxins, and gases. His current work includes sustainable metal oxide-based biosensors for clinical diagnostics, food packaging, drug delivery, and tissue engineering, as well as investigations of interfacial charge-transfer and sensing mechanisms in metal nanoparticles. He has conducted research projects supported by multiple funding agencies and has undertaken postdoctoral research at institutions in India and South Korea.
