Query: Disappointing

Almost all of the content of this book is explained in much greater detail in any good text on cell biology. Readers who are familiar with that content and expecting something new about "bionanotechnology" will be disappointed. Readers who are not familiar with that content will be mystified by the poor summary. The acclaimed artwork is not very helpful at all. This book is way too expensive for what the reader gets in return.
