Curricular information is subject to change.

This module introduces students to the core concepts, tools, and interdisciplinary nature of biophysics — the science that applies physical principles and quantitative methods to understand biological systems at all scales. The course aims to show how physics, chemistry, and biology come together to explain life at the molecular, cellular, and organismal level, with connections to medicine, pharmacology, and nanotechnology.

Through a selection of foundational topics — such as molecular forces, energy landscapes, membrane dynamics, protein folding, and cellular mechanics — students will explore how living systems operate under the same physical laws that govern the inanimate world. Real-world case studies, including recent Nobel Prize-winning discoveries, will illustrate how biophysics drives innovation in areas such as neuroscience, drug delivery, and biomedical imaging.

The module is designed to be accessible and engaging for science students from all backgrounds, offering a broad, rigorous, and inspiring introduction to a field that sits at the interface of disciplines and at the forefront of modern science.

About this Module

Learning Outcomes:

By the end of this module, students will be able to:

- Understand and explain key physical principles underlying biological structure and function, including forces, energy, entropy, and molecular motion.

- Describe how physical models are applied to biological systems such as membranes, proteins, DNA, and cells.

- Recognize the interdisciplinary nature of biophysics and its integration with concepts from physics, chemistry, and biology.

- Analyze and interpret simple quantitative models relevant to biological processes.

- Identify and discuss key biophysical techniques (e.g., fluorescence microscopy, atomic force microscopy, single-molecule manipulation) and their applications.

- Relate foundational biophysical knowledge to real-world challenges in medicine, pharmacology, and biotechnology.

- Critically engage with scientific literature and landmark discoveries in the field of biophysics.

Indicative Module Content:

The module will cover a selection of key topics that reflect the interdisciplinary scope of biophysics and its applications to modern science and technology. Indicative content includes:

- Fundamental Concepts: Forces and energy at the molecular scale; entropy and statistical mechanics; diffusion and thermal motion in biological systems.

- Molecular and Cellular Structures: Biophysical properties of proteins, nucleic acids, lipid membranes, and the cytoskeleton.

- Mechanics of Life: Molecular motors, mechanotransduction, elasticity and viscoelasticity of cells and tissues.

- Membranes and Transport: Structure and dynamics of biological membranes; ion channels; passive and active transport.

- Experimental Techniques in Biophysics: Atomic force microscopy (AFM), optical tweezers, fluorescence microscopy, and single-molecule tracking.

- Quantitative Modelling: Simple physical and mathematical models for biological systems; order-of-magnitude estimates; scaling laws.

- Biophysics in Context: Case studies from neuroscience, cancer biology, pharmacology, and nanomedicine, including Nobel Prize-winning discoveries.

This content will be delivered through interactive lectures, demonstrations, and guided discussions aimed at fostering a deep conceptual understanding and interdisciplinary curiosity.

Approaches to Teaching and Learning:
This module adopts a blended and student-centred approach to teaching and learning, combining traditional lectures with a variety of interactive and reflective strategies to promote active engagement and interdisciplinary thinking.

Key approaches include:

- Lectures to introduce core concepts and provide a structured framework for understanding biophysical principles and applications.

- Case-based learning, using real-world examples and landmark studies (including Nobel Prize-winning work) to connect theory with practice.

- Enquiry and problem-based learning, where students explore open-ended questions and develop simple models to explain biological phenomena.

- Task-based learning activities, such as estimating physical quantities in biological systems, interpreting experimental data, and critiquing scientific papers.

- Peer and group work, encouraging discussion, collaborative problem-solving, and exposure to diverse perspectives.

- Optional student presentations, offering the opportunity to explore specific biophysical topics of interest and develop scientific communication skills.

- Reflective learning, encouraging students to connect new concepts with their prior knowledge from physics, chemistry, and biology.

These varied approaches aim to foster curiosity, analytical thinking, and a deeper appreciation of the role of physics in understanding life.
