IN FOCUS: Making the Most of Your Microscope.

Above: A selection of stage plate inserts 3D printed by the Bioimaging Research Hub – links to resources in blog article below.

Hands up if your microscope is badly in need of upgrade or repair but your budget won’t stretch that far? Maybe a new focusing knob to replace the one that just broke off in your hand, or perhaps a new stage plate adapter, reflector cube or filter holder to increase your imaging options? Perhaps a C-mount or smartphone adaptor to give one of your old microscopes a new lease of life? Or even a sample holder or chamber for a bespoke imaging application? What the heck, let’s think big eh? How about a completely new modular microscope system with tile scanning capabilities?

Way too expensive, eh?… Well, imagine for a moment that you could just click a button (or a few buttons, at least) and make it so. If you haven’t yet realised, I’m talking about 3D printing in light microscopy and the life sciences – the subject of a very interesting paper that I recently came across  – see below.

It’s safe to say that 3D printing is changing the way we do things in microscopy, now permitting low-cost upgrade, repair, or customisation of microscopes like never before. There are now a huge selection of 3D printable resources available through websites such as NIH3D, Thingiverse etc that can be used to modify your microscope system or to generate scientific apparatus or labware for upstream sample processing and preparation procedures.

So, to save you trawling through the 3D printing sites in order to identify the most useful designs to meet your histology and imaging needs we’ve done it for you and have curated a list of 3D printable resources which we hope you’ll find useful (below).

SPOKE EQUIPMENT: X-Clarity Tissue Clearing System.

One of the problems associated with imaging fluorescence in large biological samples is the obscuring effects of light scatter. Traditionally this has meant physically sectioning the material into optically-thin slices in order to visualise microscopic structure.  With the advent of new volumetric imaging techniques, e.g.  lightsheet microscopy, there is increasing demand for procedures that allow deeper interrogation of biological tissues. With this in mind, an innovative clearing system has recently been purchased through generous donations to the European Cancer Stem Cell Research Institute (ECSCRI). The equipment, which will be housed in ECSCRI lab space, allows large, intact histological samples to be rendered transparent for fluorescent labelling and 3D visualisation by confocal and lightsheet microscopy.

The X-Clarity tissue clearing system is designed to simplify, standardise and accelerate tissue clearing using the CLARITY technique (an acronymn for Clear Lipid-exchanged Acrylamide-hydridized Rigid Imaging/Immunostaining/in situ-hybridization-compatible Tissue hYdrogel). In the technique,  preserved tissues are first embedded in a hydrogel support matrix. The lipids are then extracted via electrophoresis to create a stable, optically transparent tissue-hydrogel hybrid that permits immunofluorescent labelling and downstream 3D imaging.

The new equipment and associated reagents will have wide relevance to many areas of research in Cardiff,  including deep visualisation of breast cancer tumours by Professor Matt Smalley’s research group  using  the Bioimaging Hub’s new lightsheet system. You can see a video here that shows the power of the  CLARITY technique for high resolution 3D visualisation  of tissue and organ structure.

SPOKE EQUIPMENT: New Ultimaker 3 ‘Extended’ 3D Printer.

Above: The new Ultimaker ‘Extended’ 3D printer building a stage insert for a novel microscope system.

The Bioimaging Research Hub has recently purchased an Ultimaker 3 ‘Extended’ professional 3D printer. The printer will allow users to 3D print bespoke pieces of scientific equipment or generate scale models  of microscopic samples for use in their research as well as for teaching, outreach and engagement activities (examples can be  found  here and here).

The 3D printer utilises FDM (Fused Deposition Modelling) printing technology and has a range of advanced features allowing the fabrication of professional quality, high resolution 3D prints. The printer can print in two different colours or a single colour in addition to a dissolvable PVA support scaffold, thus allowing complex overhanging structures to be printed at high fidelity whilst significantly reducing  finishing time.

The printer has a large build volume (215 x 215 x 300mm), supports a range of materials (nylon, PLA, ABS, CPE and PVA) and has a print resolution of 20-200 microns.  The printer is wi-fi enabled with an internal webcam so that users can remotely monitor the progress of their 3D prints.

Further details of the equipment are available through our equipment database.

IN-FOCUS: Bigging It Up: 3D Printing to Change the Shape of Microscopy.

3d pollen

Virtual to reality: a surface-rendered digital image of a single pollen grain generated by confocal microscopy (left) is 3D printed into a 2000x scale replica model (centre & right).

Imagine being able to generate a highly accurate, solid scale replica of the sample that you are visualising down the microscope; a perfectly-rendered pollen grain, or blood cell, or microscopic organism, but big enough to hold and examine in your hand.  It would allow much better 3D conceptualisation of the sample, particularly for blind or visually-impaired individuals, and would have enormous utility in teaching and in engagement activities, and what researcher wouldn’t want a tangible, physical embodiment of their research to help explain their work (and impress their colleagues) at scientific meetings? Sounds like the stuff of science fiction doesn’t it? Well, not any more. Thanks to 3D printing technology (and the help of Dr Simon Scofield‘s lab) we have started taking volume datasets from the confocal microscope out of the virtual world and making them a reality. If you would be interested in generating a highly accurate scale model of your favourite biological sample (or would simply like to handle a giant pollen grain!) then please feel free to get in touch.
