BIOE 507: Technical Foundations in Functional Magnetic Resonance Imaging
Technical Foundations in Functional Magnetic Resonance Imaging
Theory and applications of functional magnetic resonance imaging. The advent of new neuroimaging techniques such as functional magnetic resonance imaging (fMRI) has symbolized a new era of neuroscience. A large amount of neuroscience research today involves utilizing fMRI given its high spatial resolution and whole-brain coverage. In order to gain an in-depth understanding of these research findings, it is important to know the principles of fMRI. In this class we will address questions such as: What signal do different fMRI methods measure? How to interpret the results from different fMRI techniques? How to apply these methods to solving real neuroscience problems?
BIOE 508: Biomedical Materials
Properties and methods of producing metallic, ceramic, and polymeric materials used for biomedical applications. BIOE 508 BIOE (MATSC) 508 Biomedical Materials (3) The topical content of this course will be grouped into 4 areas. A general introduction to selected aspects of physiology will be presented. This will provide the background necessary to appreciate the factors which govern the selection of biomedical materials. Specific emphases will be placed on the polymerization of biopolymers (polypeptides and polysaccharides) and the general relationships between conformation and biological function, the biochemistry of blood and blood surface interactions, the formation of teeth and bone and the relationships between microstructure, composition and function, the immune responses to implanted materials, the resorption of bone (osteoporosis),and the development of caries. The perspective placed on these topics will be that of materials science. The selection of ceramics for hard tissue prosthesis will be described. Orthopaedic and dental applications for ceramics will be discussed. Specific ceramic materials to be treated include dental porcelain, alumina- and zirconia-based ceramics, and bioglasses. Various classes of inorganic cements, gypsum, zinc phosphates, zinc carboxylates, silicates, and glass-ionomer cements will also be considered as ceramics. Hydroxyapatite, HAp-based composites and HAp-metal interactions will be discussed in particular. Relationships among physical properties, mechanical properties, and chemical interactions with biological fluids will be described.Dental and orthopaedic applications of metals will be described. The fracture toughness of metals, their electrochemical responses in vivo, and the nature of the interfacial interactions with hard tissues will be treated. Dental amalgams and the noble metals for dental applications will be considered. Metals and alloys, such as Ti, Co-Cr, and stainless steel used in prosthetic applications will be described and their properties and limitations discussed. The phenomenon of stress shielding and the immune responses associated with the accumulation of metallic and polymeric particulate debris in the vicinity of an implant will be discussed in particular.Polymeric materials are important in a broad range of biomedical applications. Among these are soft tissue prostheses, hemostatic agents, dental restoratives, bone replacement materials, and surgical adhesives. In some applications, it is desirable that a polymeric material biodegrade while in others property retention is desirable. Because of the spectrum of applications for polymers, the topics to be covered will be limited with the intent to concentrate on hemocompatible polymers, acrylics used as bone cements, polyethylene used as bearing surfaces in prostheses, and dental resins and bonding materials. Other relevant polymers and their applications will be discussed.

Biomedical Applications of Microelectromechanical Systems (BioMEMS) and Bionanotechnology
Introduction to BioMEMS and Bionanotechnology. Topics include: electromechanical and chemical biosensors, microfluidics microscale separations, and surface patterning for cellular engineering. BIOE 510BIOE 510 Biomedical Applications of Microelectromechanical Systems (BioMEMS) and Bionanotechnology (3) Microelectromechanical systems (MEMS) have been developed for a wide range of applications from automotive to medical devices. Nanoscale devices within MEMS have a particular usefulness in biological applications due to their small volumes, low energy sensing, and minimal force actuators. Increased efficacy of instruments and new areas of application are also emerging from specific and successful biomedical applications of MEMS (bioMEMS). Advanced development of nanotechnology and bioMEMS for biomedical and biotechnological applications requires basic foundations from biophysics, biochemistry, solid state devices, and polymer engineering.The objectives of this course are: to build a basic foundation for understanding of mechanisms on electrical, mechanical, chemical, and optical transducers in the context of biomedical applications; and, to teach critical thinking considering microengineering design and fabrication, material compatibility with biological systems, and cellular interaction at the interface. Finally current MEMS activities will be reviewed with emphasis on the examination of the viability of nanoscale devices and bioMEMS technology in particular biomedical applications.

Special properties of surfaces as an important causative and mediating agent in the biological response to materials. BIOE 517BIOE 517. (MATSC 517) Biomaterials Surface Science (3)This course will factor the classical picture of the biological response to materials into spatial and temporal components, identifying the special properties of surfaces as an important causative and mediating agent. Emphasis will be on biophysical mechanisms and the biological response to materials. Contact activation of blood plasma coagulation cascade, bioadhesion, and protein adsorption will be repeatedly used as example biological response to materials surfaces to illustrate concepts and principles. Leading theories attempting to correlate both kinds of intensity of biological responses to surface and interfacial energetics will be compared and contrasted through a process that will quantify important surface thermodynamic properties of materials. The hydrophobic effect and related phenomena, especially as this pertains to water solvent effects in biology, will receive special emphasis. A general background in chemistry and/or biology is required, but prerequisites are purposefully limited, reflecting the interdisciplinary aspects of the subject and to draw students from different specializations.
