Confocal and Super-resolution Microscopy Facility

Within the Bioimaging Centre in the School of Engineering and Materials Science we have the following two confocal microscope systems: a Nikon CSU-W1 SoRa spinning disk, and a Zeiss LSM710 Elyra PS.1 super resolution system purchased through the Institute of Bioengineering, as well as two standard epifluorescence microscopes and an incubator based microscope for live cell imaging, and Chiaro nanoindenter mounted with Leica DMi8 for measuring mechanical parameters of cells and materials. The bioimaging facilities have contributed significantly to the publication output in SEMS.

 

Zeiss Super resolution LSM710 ELYRA PS.1

LSM 710 ELYRA PS.1 is a combination of an inverted laser scanning confocal microscopy 710 (LSM 710) with super resolution imaging microscopy ELYRA PS.1: photo activated localization microscopy (PALM)/Stochastic Optical Resolution Microscopy (STORM) and structured illumination microscopy (SIM). It is suitable for imaging targeting at 10-100nm resolution at single molecule level. In addition, Zen 2012 software, motorised X/Y stage, definite focus, TIRF mode make it capable of acquisition of tiling, multiple positions, time lapse, FRAP and FRET. It has a on stage environment chamber with a 35mm petri dish adaptor linked with a CO2/N2 controller for live cell imaging including hypoxic experiments. Furthermore, it comes with an offline data processing workstation.

Chiaro Nanoindenter

Chiaro Nanoindenter

The Chiaro nanoindenter is the ideal nanoindentation instrument to explore the micro-mechanical properties of cells, spheroids or other small samples. Therefore, this instrument is purposely built to measure forces on cells and micro-materials while placed on an inverted microscope Leica DMi8. The Chiaro nanoindenter is capable of measuring many mechanical parameters. These include the Young’s Modulus (E), storage (E’) and loss moduli (E”). Moreover, both, static and dynamic indentation can be performed using this instrument, including creep, stress-relaxation and DMA.
