Module summary

Using physics to understand biological systems has been key to solving real-world problems, from designing better medical treatments to developing sustainable nanotechnology inspired by nature. Biological life does not break the laws of physics; instead, it harnesses them in remarkably sophisticated ways to create systems that can self-assemble, transport, harvest energy, send and detect signals including light, temperature, force, and electrical charge. This module will explore how physics is used to understand biological systems across length scales, from molecules and their nanoscale assemblies to cells and tissues. It will also explore the experimental techniques developed to analyse the physical properties of biological systems. Wherever possible the physics of the systems will be treated quantitatively making use of techniques and concepts acquired in foundational physics courses.

Objectives

Provide students with the opportunity to consolidate their physics curriculum by applying physics knowledge to the study and mechanistic understanding of biological systems. Such education is relevant to a wide range of areas such as understanding disease, diagnostics, analytical techniques, new materials and devices, and energy.

Learning outcomes

Students will be able to demonstrate knowledge, understanding and application of:

1. Self-assembly and properties of soft biological matter
2. Mechanics across multiple length scales, from molecules to cells to tissues
3. Selectivity and recognition in biological systems
4. Movement, signals and noise in biological systems
5. Chlorophyll photophysics and solar energy capture
6. Biophysics of light harvesting proteins and membranes

Skills outcomes

• Applying physics to biology, and for applications in biomedicine, biomaterials and biotechnology
