Not open to students who have taken or are taking PHYS 319.
Emerging physical approaches and quantitative measurement techniques are providing new insights into longstanding biological questions. This undergraduate course will present underlying physical theory, quantitative measurement techniques, and significant findings in molecular and cellular biophysics. Principles covered include Brownian motion, low Reynolds-number environments, forces relevant to cells and molecules, chemical potentials and free energies. Those principles are applied to enzymes as molecular machines, DNA and RNA. U2 and U3 students with training in physics and quantitative biology will be well-suited to the course.

Topics covered (not necessarily in order):

Introduction to physical biology and quantitative modeling.
Brownian motion and diffusion.
Stokes-Einstein relation and applications.
Gibbs free energy and Entropy.
Kramers theory, diffusion-limited reaction rates, and dynamics in the cell.
Mechanical and chemical equilibrium in the living cell.
Chemical binding kinetics, membrane receptors
Intermolecular forces.
Electrostatics in salty solutions.
Cellular membranes and membrane potential
Cytoskeleton and dynamics.
Biophysics applications of fluorescence and super-resolution optical microscopy
Physical Biology of the Cell, 2nd ed. by Rob Phillips, Jane Kondev, Julie Theriot, Hernan Garcia Garland Science 2012
