PHYS*4560/7510 Biophysical Methods

Department of Physics, University of Guelph

Guelph-Waterloo Physics Institute

Course Outline - Fall 10

This course introduces students to a wide variety of physical techniques used in modern biophysics research. The molecular biophysics of cellular membranes will be discussed in detail, including the structure and function of major membrane components, lipids, proteins and carbohydrates. The course also aims to improve the oral and written communication skills of the students. The course work assumes knowledge of quantum mechanics and statistical mechanics at an introductory level. It is also very useful if the students have had an exposure to molecular biology and biochemistry.


Lecturer: John Dutcher MacN 451 ext 53950 dutcher at uoguelph.ca

Polymer Surface and Interface Group In John's research group, a wide range of state-of-the-art, surface-sensitive techniques are used to probe the interaction of polymers, biopolymers and bacterial cells with a variety of different surfaces, ranging from atomically-flat surfaces to tethered lipid bilayer films to industrial-grade and food surfaces. By tuning both the properties of the surfaces and the polymer and biopolymer molecules, and developing simple models to interpret the data, an understanding of the underlying physical, chemical and biological principles and therefore predictive power in the design of novel technologies can be obtained.

Lectures and Seminars: Tues., Thurs. 11:30 - 12:50, Guelph-Waterloo Link Rooms: MacN 101 (Guelph campus), EIT2053 (Waterloo campus)

Calendar Description:

An introduction to physical techniques to determine the structure of macromolecules and macromolecular structures of biological interest. The techniques include: differential calorimetry, X-ray and neutron scattering, electron microscopy, Raman and infrared spectroscopy, nuclear magnetic resonance, single molecule techniques such as atomic force microscopy, and surface adsorption techniques. Applications of these techniques in the study of proteins and biological membranes will be emphasized. Students taking this course should already have taken PHYS*4240 (Statistical Physics II) or the equivalent course, or be taking such a course concurrently.


Prerequisites:

PHYS*3220 (Waves and Optics)

PHYS*4040 (Quantum Mechanics II)


Co-requisites:

PHYS*4240 (Statistical Physics II), if not taken as a prerequisite


References:

The students will be provided with an electronic collection of important reviews on the techniques of interest (licensed to University of Guelph). This collection of reviews is also available for download in the "cd" directory at the following website:

Tentative Outline (can be slightly modified due to an unknown number of student presentations):

- introduction to biological membranes

- formation of lipid structures

- forces between lipid bilayers

- membrane protein structure

- samples in biophysics: cells, membranes, films, crystals, liposomes

- vibrational spectroscopy of biomolecules

- single molecule techniques

- protein adsorption techniques

- guest lectures throughout semester

- student presentations on research papers and biophysical techniques not covered by the lectures


Course Objectives:

        -Introduce the students to a wide variety of physical techniques used in modern biophysics research, and the biological concepts that can be probed using these techniques. Techniques will include (to various degrees of sophistication) differential scanning calorimetry, X-ray and neutron scattering and diffraction, NMR and ESR spectroscopy, infrared and Raman spectroscopy, electron microscopy, atomic force microscopy, absorption spectroscopy, light scattering, circular and linear dichroism, fluorescence, as well as other methods.

        -The course is also an introduction to the molecular biophysics of cellular membranes. The structure and function of the major membrane components, lipids, protein and carbohydrates will be discussed. The determination of the molecular structure and function using physical techniques will be emphasized.

        -Another objective of the course is to bring the students to a level of understanding of the field of biomembranes where they are comfortable reading the most recent research literature such as that reported in the Biophysical Journal. The students will be encouraged to explore the literature associated with biophysical systems and techniques.

        -The course also aims to improve the oral and written communication skills of the students. Each student will have the opportunity of reviewing an important research paper in the field. In addition, each student will give an oral presentation on some physical technique used in modern biophysical research and will lead a class discussion on this topic. A final essay will also be submitted on the same physical technique. The topic should not be directly related to the student's own research work and not extensively covered in the lectures. Graduate students taking the course will have to write an additional research proposal on applying biophysical techniques to a given problem.

HELP!:

Short questions can often be handled in the lecture room just before or after lectures. John will make every effort to answer emails in a timely manner.


Collaboration versus Copying:

Scientists often consult fellow scientists to discuss their research problems. Collaboration between scientists is often essential to perform world-class research. However, no ethical scientist would ever publish or claim the work of others as their own. Instead, joint publication or acknowledgements of the contributions of their collaborators is given.

The work that you submit for marking must be your own and not a copy of someone else's work. As a young scientist, you are encouraged to discuss with your fellow students as you learn the material and work on your assignments and presentations. However, plagiarism is a form of academic misconduct, and will not be tolerated. In your work that you submit for marking, you are encouraged to cite references and acknowledge discussions with others who have helped you to achieve an understanding of the material. This is good scientific practice.


Student Assessment for Guelph Students:

The Department of Physics requires student assessment of all courses taught by the Department. These assessments provide essential feedback to faculty on their teaching by identifying both strengths and possible areas of improvement. In addition, annual student assessment of teaching provides part of the information used by the Department Tenure and Promotion Committee in evaluating the faculty member's contribution in the area of teaching.

The Department's teaching evaluation questionnaire invites student response both through numerically quantifiable data, and written student comments. In conformity with University of Guelph Faculty Policy, the Department Tenure and Promotions Committee only considers comments signed by students (choosing "I agree" in question 14). Your instructor will see all signed and unsigned comments after final grades are submitted. Written student comments may also be used in support of a nomination for internal and external teaching awards.

NOTE: No information will be passed on to the instructor until after the final grades have been submitted.


Note:

John may be away several times during the semester to attend workshops and conferences, and to give research lectures. John will try to arrange that lectures be given at the regular times by enthusiastic and talented replacement and guest lecturers. Otherwise, makeup lectures will be arranged at times that are agreeable to the students.
