CENG 256 BIOMATERIALS AND BIOMIMETICS (B&B)
1-1:50 PM MWF
Instructor: Marc André Meyers (M&M)
Associate Instructor: Po-Yu Chen (P&C)
Materials Science and Engineering has initially merged metals, polymers, ceramics, and composites into a broad and unified treatment. Whereas the 20th century was marked by revolutionary discoveries in physics and chemistry, the 21st century has been prognosticated to be biology. Indeed, medical and biological discoveries are bound to have a profound effect on our future. Consistent with the increasing demands of engineering students to acquire basic working tools in this domain, many engineering curricula are adding appropriate courses or modifying existing courses to address biological aspects. Within MSE, the nascent area of Biological Materials Science encompasses three areas:
· Biological (or natural) materials: materials that comprise cells, extracellular material, organs, and organisms.
· Bioinspired materials: this area encompasses the materials and structures inspired by biological systems and/or functions.
· Biomaterials: synthetic materials used to correct, repair, or supplement natural functions in organisms.
The course will focus on the first two of these three areas in a balanced manner. In appropriate places some concepts of biomaterials will be introduced. The course is geared for seniors and first year graduate students
Many courses in biomaterials devote the first half to explain the principles of MSE and are designed for bioengineering and medical students. They fall into two categories:
a. Biomedical approach, emphasizing biocompatibility, implants.
b. Mechanics approach, with emphasis on biomechanics.
The opposite approach will be implemented here: we will present the principles of biology and the structure-properties connections in biological materials. We will use the Materials Science and Engineering approach, which is based on the correlation of structure with structural and functional properties.
The intended audience for this course are MSE and ME students with a sound MSE background and poor biology background. In selected places, we will introduce innovations in biomaterials rather than the classical, well established alloys, ceramics, and polymers. A unique aspect of this course, not treated heretofore in classrooms, is the bioinspired design of materials and structures. Some of these bioinspired materials are already used in biomedical applications.

5. Principal Sources for Class
1. P. Fratzl, ed. Collagen: Structure and Mechanics, Springer, 2008.
2. Peter Forbes, The Gecko's Foot: Bio- Inspiration: Engineering New Materials from Nature, 2006. (recommend purchasing on amazon.co~$20 used)
1. Biomechanics, Biodynamics Y. C,. Fung, Springer. These classic books (four of them) are very complete accounts of the field. They have probably over 1000 references and the mechanics part is strong, since Prof. Fung’s background is in aeroelasticity. He is the ‘Timoshenko’ of biomechanics. However, the books are too detailed and advanced for use as undergraduate/beginning graduate texts. There are no problems at the end of chapters.
2. Biomaterials Science, B. D. Ratner et al. eds., Elsevier 850 super pages(double column). This is a comprehensive book written by approximately 50 persons and edited by four. This poses a problem for students. Too many cooks spoil the food. The book, 800 tightly written pages, is an excellent reference and is closer to an encyclopedia. Nevertheless, it has been used as a text by default.
3. Biomaterials, An Introduction
(third edition) J. Park,
Main focus is implant materials. The first eight chapters are traditional MSE with occasional input /figures from biomaterials. Chapters 9-16 cover biological materials and biomaterials.
The book has been successful and is geared at undergraduates. Book has end-of-chapter problems and solved examples inside the chapters.
4. Biomaterials J. S. Temenoff, A. G. Mikos, Prentice Hall, 474 pages
Primarily an undergraduate book. First 7 chapters cover basics of MSE. Chapters 8-14 go into the details of interaction of cells and proteins with biomaterials, immune response, infections, etc. Solved examples and end-of-chapter problems. This is primarily an undergraduate text.
5. Biomaterials, eds. J. Y. Wong, J. D. Bronzino, CRC Press, ~200 pages.
Approximately 20 authors. Focus is on implant materials (metals, ceramics, polymers, composites). Some new ideas on biodegradable and biologic biomaterials.
6. Biological Performance of Materials, J. Black, Taylor &Francis (fourth edition), 492 pages. Traditional MSE with bio-implants.
