PHY3061 The Biophysics of Cells and Tissues 2018-19
Dr J.R. Meakin
Delivery Weeks: T1:01-11
Level: 6 (NQF)
Credits: 15 NICATS / 7.5 ECTS
Enrolment: 44 students (approx)


This module describes the fundamental physical properties of biomolecules, cells and tissues and introduces some of the biophysical and biomechanical challenges in understanding the behaviour of normal tissues and their failures in disease.

Module Aims

The physical properties of tissues and their constituent cells and biomolecules are central to their biological functions. Physical processes are also vital to normal growth and development and diseases, ranging from arthritis to cancer, may be related to failures in these processes.

Intended Learning Outcomes (ILOs)

A student who has passed this module should be able to:
