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. Jay, 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. 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.
