Fluid mechanics analysis of blood flow in a pump.
Research in the biofluids and cell mechanics laboratory focuses on the interactions between physiological fluids and biological tissues. At the macroscopic level, we work on blood circulation in bypass grafts, aortic valve mechanics and stress and strain distributions in the atrial wall. At the microscopic level, we investigate flow and solute transport in extracellular matrices and interactions between flow and endothelial cells, with a particular interest in the endothelial glycocalyx. All these studies aim to reveal fundamental mechanisms involved in vascular and soft tissue function in health and disease.
Cell & Tissue Engineering Laboratories
Students doing a lab practical as part of the the Tissue Engineering module.
The cell and tissue engineering laboratories provide extensive facilities for tissue engineering, mechanobiology and biomechanics research and teaching. The facilities include five dedicated cell culture laboratories, a molecular biology facility and general purpose and biochemistry laboratories. The labs house machines for mechanical testing of biological tissues or implantable materials as well as equipment for a wide range of biochemical/cell biology analysis.
Confocal Laser Scanning and Super Resolution Microscopy Lab
Confocal fluorescence 3D reconstruction of tendon cells (nuclei labelled blue, primary cilia cytoskeleton red)
The School of Engineering and Materials Science hosts a confocal microscopy containing two laser scanning confocal microscopes - a Perkin Elmer spinning disc system and a Leica SP2 with multiphoton laser and lifetime imaging system.
In addition the Institute of Bioengineering will soon be purchasing a new confocal microscope associated with a super resolution system. The unit enables live cell fluorescence imaging (GFP, calcium imaging etc), 3D reconstruction and morphological measurement, photobleaching assays such as FRAP and FLIP and fluorescence lifetime microscopy(FLIM). The microscopes also interface with sophisticated mechanical loading systems for tissues, individual living cells (micropipette aspiration) and artificial constructs.

Gait Analysis Laboratory
Undergraduate students using the force plate for their 4th year project.
The Kidman (Gait Analysis) lab allows us to analyse motion and forces in people during walking, running and many other activities. These state of the art facilities allow us to assess normal subjects, elite athletes, patients who have had an operation, or individuals with some disability. The wide range of equipment available includes a force plate in the ground, a treadmill that can accommodate wheelchairs and motion analysis facilities, as well as sensors for indicating when muscles are activated and an oxygen consumption monitor. All of these are used for undergraduate, clinical and research projects.
Hip Wear Simulator
Student testing total hip replacement implants using the hip wear simulator.
The wear testing lab is able to assess the likely success of developments in total hip replacements. We work with a range of companies, including Johnson & Johnson Orthopaedics, Corin and Finsbury to evaluate designs before they are implanted into patients. Exciting research ideas are tested such as coatings which make the prosthesis last longer. These coatings are evaluated in our hip joint simulator and the biological response to the particles that are created is also studied.
Mechanical Testing Facilities
Students using mechanical testing equipment.
The School has a variety of mechanical testing equipment used to determine the mechanical properties of different materials and structures ranging from aircraft components to new implant materials or even biological tissues. These testing machines apply forces in compression, tension or torsion and can be used to find out material properties such as ultimate strength and modulus.
Mechanobiology and BioAFM Laboratories
Micropipette aspiration of a living stem cell
The School of Engineering and Materials Science in association with the Institute of Bioengineering has extensive multi-user mechanobiology facilities.
This includes a range of bioreactor systems for subjecting living cells to dynamic mechanical loading in the form of tensile strain (Flexcell), compressive strain (Bose) and fluid shear (Osciflow & Bose). These loading systems are mounted in cell culture incubators for long term loading studies.
We also have equipment for measuring cellular mechanical properties and mechanically stimulating individual cells using biological atomic force microscopy (bioAFM), micropipette aspiration or custom built scanning ion conductance microscopy.
In addition we have a range of mechanical test machines for measuring the mechanical properties of biological tissues and biomaterials under dynamic, uniaxial and biaxial loading conditions.

Medical Electronics Lab
Students working in the Medical Electronics Lab
The medical electronics laboratory is a customised workspace for undertaking electronics work, with specific expertise in the medical field. The wide range of medical equipment includes ECG monitors, ultrasound probes and pulse oximeters. The laboratory also contains a wide range of electronics components and prototyping boards, as well as microprocessor software, to make your own circuitry. The facility is used for a range of taught laboratories that focus on circuit design, and is also available for MSc projects.

The NanoVision Centre is a state-of-the-art microscopy unit which brings together the latest microscope techniques for structural, chemical and mechanical analysis at the nanometer scale (1/1000000 mm). The facility contains an impressive range of electron microscopes, scanning probe microscopes and associated analytical equipment for use in the cutting-edge research being conducted by students and staff.
FTIR equipment for materials analysis.
We have a variety of sophisticated spectrometers which are used to identify specific compounds and investigate composition of materials prepared as either a liquid, solid, film or powder.
These devices include:
- Fourier Transform Infrared Spectroscopy (FTIR)
- Raman Spectroscopy
- Near InfraRed Spectroscopy (uv-vis NIR).
Thermal Analysis Facility
Differential Scanning Calorimeter.
We have a variety of excellent techniques for analysis the thermal properties of materials such as melting temperature, glass transition temperature, viscosity, thermal expansion and thermo-mechanical properties over a range of temperatures (-150 to 1600C).
The techniques include:
- Differential Scanning Calorimetry (DSC)
- Thermo Gravimetric Analysis (TGA)
- Simultaneous Thermal Analysis (STA)
- Dynamic Mechanical Analysis (DMA)
Undergraduate Teaching Labs
We have recently invested £8M in major new teaching laboratories to provide state-of-the-art experimental facilities specifically for teaching of undergraduate students.
Opened in 2016 the lab provides a space on the ground floor with step free access and has a height adjustable bench installed for wheelchair users.
Workshops for Engineering Manufacture
The School has a purpose built, fully equipped teaching workshop where students learn the basics of workshop practice in line with the degree accreditation requirements of the Royal Aeronautical Society and the Institution of Mechanical Engineers. In addition, it contains fully automated CAD/CAM controlled milling machines and two rapid prototyping machines for high speed production of complex components. The workshops are also used during students design build and test projects as part of their Engineering Design modules.
