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.

The School has a wide range of electrochemical and photoelectrochemical facilities for testing of energy materials. These include:
(1) Xe lamp 400W with solar simulator filter, potentiostat and electrochemical cell: for photocurrent measurements of photoelectrodes in multiple electrolytes, in a three-electrode (half cell) configuration, under 1 sun simulated conditions (with IR filter to avoid overheating of lamp and sample).
(2) Zahner photoelectrochemistry station: fully integrated photoelectrochemical workstation for high accuracy QE/IPCE measurements. Also with a tuneable LED light source that allows to measure photocurrent response at different wavelengths and possibility of measure electrochemical impedance spectroscopy, too.
(3) Rotating Disc Electrode (RDE) and potentiostat (with FRA for measuring electrochemical impedance spectroscopy): RDE in three-electrode electrochemical cell configuration with potentiostat to measure the electrocatalytic activity of new materials towards the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR)
(4) Potentiostat Biologic (+/- 5V -10A) and redox flow battery system: for measuring the performance of electrode materials in full cell configuration for redox flow cell applications.

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.
Nano Fluids Research Labs
The School has a rapidly expanding group working on heat transfer from nano-fluids which are liquids containing nano-scale particles that act to alter the fundamental thermo-physical properties of the fluid and so increase heat transfer rates. The specific research includes formulation of nanoparticles and stable nanofluids in a purpose built laboratory. In addition, a new test facility is being constructed to investigate flow and heat transfer behavior of nanofluids in micro-tubes. The research will include mechanistic analysis of micro/nanoscale energy transportation and enhanced heat transfer performance.
Scanning electron microscopy (SEM) image of human bone from a patient with osteoporosis.
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.
Light-Addressable Potentiometric Sensors (LAPS) and Scanning Photo-induced Impedance Microscopy (SPIM) are imaging techniques based on photocurrent measurements at electrolyte/insulator/silicon (EIS) field-effect structures. They are capable of measuring local changes in the surface potential (LAPS), which can be used to image ion concentrations, and of measuring the local impedance (SPIM).
LAPS and SPIM have great potential as tools for functional electrochemical imaging of the attachment area of cells, providing information such as ion concentration, extracellular potentials and cell impedance. The techniques are particularly attractive for analysing responses of cells with planar polarisation or cell types that separate one compartment from the other as the cell-surface attachment area is not accessible to conventional electrophysiological and electrochemical imaging.
A ThermoFisher Nexsa X-ray Photoelectron Spectrometer (XPS) System enables a range of photoelectron spectroscopy measurements on a range of materials. It includes facility for:
- X-ray photoelectron spectroscopy (XPS)
- Ultraviolet photoelectron spectroscopy (UPS)
- Reflection electron energy loss spectroscopy (REELS)
- Ion Scattering Spectroscopy (ISS)

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.
The X-ray Diffraction Facility (XDF) offers a full diffraction analysis service in materials science, structural chemistry, structural biology and solid state science.
The facility is located in the Francis Bancroft building (room G.30) at the Mile End campus, and is operated by the School of Biological and Chemical Sciences
