Lectures
Biological Molecules 6: An introduction to molecular biology and evolution
Jan 1, 2013
How evolution can be studied at the molecular level.
Biological Energy 3: Light, energy and upstream processes
Jan 1, 2013
An introduction to the chemical and physical processes involved in photosynthesis
Biological Energy 4: Molecular energy transfer and photobiology
Jan 1, 2013
The energy-transfer process in photosynthesis.
Biological Energy 5: Electron transfer theory
Jan 1, 2013
An explanation of the essential process of electron transfer in photosynthesis.
Supplementary lecture: Chemical reaction kinetics and equilibrium
May 11, 2012
This lecture provides chemistry background to lectures in biological physics. It can either be presented in a single session or be drawn upon to provide supplementary material as and when needed for the biological physics lectures.
Regulatory networks 1: Introduction to regulatory networks
May 11, 2011
The binding of proteins and DNA can control cell behaviour by turning genes on and off.
Regulatory networks 2: The physics of biological regulation
May 11, 2011
Some simple models can tell us a lot about how regulatory networks work.
Regulatory networks 3: Biochemical noise
May 11, 2011
Cells with identical genes in identical environments can behave differently. This can be explained in terms of biochemical noise.
Thermodynamics 1: Statistical mechanics
May 11, 2011 1 comment
Statistical mechanics (or statistical thermodynamics) provides methods for circulating the probability that a system with a very large number of components will be found in a given state, and hence predicting its most likely state.
Thermodynamics 2: Brownian motion
May 11, 2011
The movement of particles in a fluid can be described in terms of the average behaviour of a large number of particles in random motion.
Thermodynamics 3: Amphiphile aggregation - critical micelle concentration
May 11, 2011
The formation of micelles and bilayers can be described in terms of statistical thermodynamic functions, such as chemical potential and free energy.
Thermodynamics 4: Micelle geometry
May 11, 2011
The size and shape of a micelle are determined by the geometry of its constituent molecules and by the forces that act between them.
Thermodynamics 5: Lipid bilayers
May 11, 2011
Biomembrane deformation, governed by curvature elasticity, is important in many biological processes.
Thermodynamics 6: Fluctuating membranes
May 11, 2011
The thermally driven roughness of membranes can be analysed statistically
