Background

Dr. Anil Kumar Patri received his Bachelor of Science degree in chemistry and biology from Osmania University, India, in 1987. After working with Astra IDL (Astra Zeneca) for a year, he obtained his Master of Science in organic chemistry from Aligarh Muslim University, India. He then worked as a lecturer in chemistry before moving to the U.S. and earning his Ph.D. in chemistry from the University of South Florida where he worked on the synthesis of novel nano-sized dendritic polymeric material. Dr. Patri received the “Provost’s Award for Outstanding Research” and the “Tharpe Award for Teaching” while in graduate school. He then pursued postdoctoral research at the University of Michigan Medical School, Center for Biologic Nanotechnology, developing multifunctional targeted drug-delivery and imaging systems using nanomaterial. While at Michigan, he was a co-principal investigator on a number of federally funded grants working in a collaborative interdisciplinary team environment.

Dr. Patri moved to the National Cancer Institute’s Nanotechnology Characterization Laboratory (NCL) in 2005. There he established the Physico-Chemical Characterization Facility and served as deputy director and principal scientist. In a decade-long tenure at NCL, he worked on clinical translation of promising cancer nanomedicines and also oversaw the preclinical assessment of over 85 projects with proof-of-principle efficacy for cancer with a multidisciplinary research team. Based on this experience, he co-developed and taught courses with NCL staff on the lessons learned and pitfalls to avoid during the preclinical development of nanomedicines intended for cancer. He closely worked with industry, academia, and government-agency collaborators in this rewarding work that lead to ten collaborator’s products in clinical trials. Dr. Patri was a guest researcher at the National Institute of Standards and Technology (NIST) from 2006-2014 and co-led the development of the first “Nanosized Gold Reference Material Standards" with NIST colleagues. He served on many editorial and advisory boards, Small Business Innovation Research (SBIR) grant evaluation committees, and site visits for NCI-funded programs.  He continues to serve on the American Society for Testing and Materials (ASTM) Committee E56 on Nanotechnology.

Dr. Patri was recruited to direct the NCTR staff and research conducted by the NCTR/Office of Regulatory Affairs (ORA) Nanotechnology Core Facility (NanoCore) and was appointed Chair of the Nanotechnology Task Force in the FDA's Office of the Commissioner. He serves on the National Nanotechnology Initiative’s (NNI) Nanoscale Science, Engineering, and Technology Subcommittee and the Nanotechnology Environmental and Health Implications (NEHI) Interagency Working Group of the NNI. Dr. Patri also serves as the co-chair of the US-EU Communities of Research on Characterization. He has co-authored more than 65 publications, book chapters, and reviews.


Research Interests

Dr. Patri’s group conducts regulatory-science research with a focus on nanomaterial characterization, structure activity, and stability studies that help to determine the nanomaterial’s impact on safety and efficacy. Dr. Patri and his laboratory members are pursuing collaborative consensus standards development that can help regulatory agencies and industry.

The Nanocore was established as an FDA collaborative resource between NCTR and ORA. Nanocore staff members from both NCTR and ORA conduct annual hands-on training sessions for reviewers from FDA product centers. The labs are well-equipped with extensive state-of-the-art instrumentation for nanomaterial assessment, including:

  • Scanning and Transmission Electron Microscopes equipped with EDS detectors
  • Specialized Field-Emission SEM with 3-View capability
  • Low Voltage Electron Microscope
  • Atomic Force Microscopes
  • Optical, Confocal Raman, and Hyperspectral Imaging instruments
  • Chromatography, Dynamic, Static and X-ray Scattering instruments
  • Asymmetric, Centrifugal Field Flow Fractionation instruments
  • Instruments with ICP-MS, UV, Fluorescence, Charged Aerosol, and Evaporative Light Scattering Detectors
  • Thermogravimetric Analysis instruments
  • Differential Scanning Calorimetry instruments.


Current major collaborative projects include:

  • Investigation into physico-chemical attributes of nanomaterial and their influence on radiation enhancement
  • Standards development for nanomaterial characterization and in vitro assessment
  • Physiologically based pharmacokinetic analysis of liposomal drug formulations
  • Characterization and methods development for nanomaterial assessment
  • Effect of nanomaterial on stem-cell differentiation
  • Toxicity of nanomaterial in feminine-hygiene products
  • Detection, identification, characterization and quantitation of various attributes of nanomaterial in pristine state and in complex matrices
  • Investigation of nanomaterial in sunscreens
  • Biodistribution of gladolinium imaging agents
  • Genotoxicity standards of nanomaterial
  • Nanomaterial in dental composites and their effects on microbiota
  • Nanoparticle permeability through the gastrointestinal surface
  • Epigenetic effects of nanomaterial
