AFM/SPM - Keysight 5500

The Keysight 5500 Atomic Force Microscope/Scanning Probe Microscope is a high performance and highly configurable top-down scanning microscope system that offers a wealth of features.  The system is versatile – changing between the many possible imaging modes is facilitated by the use of modular sample plates and cantilever nose cone assemblies. The system can image in air, fluids, and under controlled environmental and temperature conditions in contact or alternating contact (acoustic & magnetic) modes.

The AFM is currently located in A69, Faraday Building, and the booking timetable is accessible here.

The JEOL JSM-7800F is JEOL’s industry-leading highest performance Field Emission SEM with ultrahigh resolution at ultra-low kV imaging. It has a magnification range of 25× to 1,000,000×, accelerating voltage of 10 V to 30 kV, probe current range of a few pA to 200 nA and a resolution of 0.8 nm @ 15 kV.

The SEM is currently located in A72, Faraday Building and is bookable here.

Unique JEOL features such as the Super Hybrid Lens (SHL) enable the study of magnetic materials at high magnification. The Large Depth of Focus (LDF) mode enables observation of large areas at high tilt with minimum image distortion. JEOL’s beam deceleration (Gentle Beam, GB) function reduces charging, specimen contamination and improves surface detail – significantly advancing the ability to image insulating (ceramic, semiconductor & polymer) specimens with nanometer scale resolution. Low voltage SEM enables a variety of biological and material science specimens to be analysed without surface modification.

The JSM-7800F is fitted with the latest generation high analytical performance X-ray Energy Dispersive Spectrometer (EDS) (X-Max50, large area 50 mm2 Silicon Drift Detector (SDD) from Oxford Instruments) which allows fast mapping of elemental maps and can operate in low kV conditions for analysing beam sensitive specimens.

Nanofabrication - Nanoscribe Photonic Professional GT

The Nanoscribe Photonic Professional GT is the fastest microscale 3D printer available with an achievable feature size of 1 µm and smaller. The system employs femtosecond laser pulses to cure polymers at the nanoscopic level - a technique known either as Direct Laser Writing (DLW) or Two Photon Polymerization (2PP). Fabrication of complex micro– and nanostructures in various photocurable materials such as: industry standard photoresists, hybrid sol-gels and, biocompatible and biodegradable materials (e.g. hydrogels and proteins) is possible.

The Nanoscribe is currently located in A69, Faraday Building, and bookable here.


Two writing modes ensure challenging designs can be realised:

  • galvo – enables a fast layer by layer writing approach, suitable for micrometre to millimetre scale structures
  • piezo – enables ultra-precise arbitrary x-y-z trajectories for highly complex structures

Amongst the growing number of application areas for 3D microprinting are:

  • Optical (photonic crystals & metamaterials, waveguides, interconnects, lenses, diffractive optical elements)
  • Micro- and nanofluidics (filters, mixers, nozzles and valves)
  • Biological (cell culture surfaces, biomimetic surfaces, 3D tissue engineering scaffolds and cell encapsulation)
