Muthukumar's book meticulously builds on well-presented fundamental polymer physics in order to be able to provide a firm theoretical basis for understanding the physics of translocation ... a well-thought out book, superbly written, and thus bound to remain a standard in the field. -Journal of Biological Physics, September 2012 I like very much the way theoretical ideas are presented and compared with experiments. I think this book will be a valuable source of information for anyone investigating polymer transport processes. -Professor Anatoly B. Kolomeisky, Rice University Muthu's incisive work beautifully clarifies the issues in polymer translocation. He offers cogent explanations of several experimental phenomena and indicates where our reasoning remains murky. -Hagan Bayley, Professor of Chemical Biology, University of Oxford, UK It is a truly outstanding book! The author has covered a surprisingly broad range of physical questions that refer to both polymers and ion channels. The contents quickly but carefully ascend from the beautifully presented basics up to ... advanced theoretical treatments. This book is a must read for everyone who wants to get a steadfast grip over the physics of channel-facilitated polymer transport. -Sergey M. Bezrukov, Ph.D., Senior Investigator and Section Chief, NICHD, National Institutes of Health
