Over the past ten years several sophisticated in vitro test systems based on epithelial cell cultures have been introduced in the field of drug delivery. These models have been found to be very useful in characterizing the permeability of drugs across epithelial tissues, and in studying formulations or carrier systems for improved drug delivery and enhanced absorption. Compared to in vivo trials on animals or humans, cell culture models are faster, more convenient and cost effective, ethically advantageous and, most importantly, they can be more easily standardized and validated.
This book provides a practical approach to contemporary cell culture-based in vitro techniques for drug transport studies at biological absorption barriers. It is an invaluable source of information for students attending graduate courses on this subject and pharmaceutical scientists working in industry or in academia.

Dr. Debasish Sarkar is currently a Professor at the Department of Ceramic Engineering, National Institute of Technology (NIT), Rourkela, Odisha, India. After his undergraduate in Ceramic Engineering from University of Calcutta in 1996, he completed a M.Tech in Metallurgical and Materials Engineering from Indian Institute of Technology, Kanpur, followed by a Ph.D in Ceramic Engineering at NIT, Rourkela. In due course of visiting researcher in Korea Research Institute of Standards and Science (KRISS), South Korea, he has gained extensive experience in ceramic processing for the wide perspective. As Principal Investigator, he has managed several research projects including Nanomaterials for functional and structural applications, and Refractories. The government of India and Industry like Tata Steel Ltd., Tata Krosaki Refractories Ltd, etc. sponsored most of the fund.

Debasish is internationally recognized expert in the academic and industrial research. Several works are highlighted in "Global Medical Discovery, Canada" as well as published as European patent. He has been awarded Materials Research Society (MRSI) of India Medal Award, 2016 for the work on patient-specific Orthopaedic implants, is a symbol of his outstanding career. He is life member of American Ceramic Society, Indian Ceramic Society and Indian Institute of Metals.

He has cumulative 23 years of experience and published 65 peer-reviewed international journal papers, 20 papers in conference proceedings, and 3 book chapters in Pan Stanford Publisher, Singapore, Wiley - VCH Verlag GmbH and Elsevier. In recent he has published a book on Nanostructured Ceramics in CRC Press, USA. He has been a lead inventor in one Korean patent, one European patent and one Indian Patent, and co-inventor for two Korean patents. He has published and reviewed in ACS, Blackwell Publishing Inc, Electrochemical Society, Elsevier, RSC, Springer, etc. He is holding position a member of different Editorial Board and Technical Committee around the globe.
