🚨New pre-print out now!🚨 We 3D printed a large optical element that enhanced the illumination, contrast & image quality in transmission stereomicroscopy. This simple addition to the illumination path lets us detect refractive structures & dynamics unobserved by conventional stereomicroscopy. (1/5)

🚨 New paper alert! 🚨 We used complementary sensing approaches to study oxygen microenvironments in E. coli biofilm transport channels, which provided a spatial overview of how transport channels maintain chemical gradients in complex communities. doi.org/10.1099/mic.0.001543
Orthogonal visualization presents an explanation for chemical gradients in biofilm transport channels. (a) A thin section of a fixed gfp-expressing E. coli JM105 biofilm is presented with arrows at the apical surface indicating regions where transport channels can be viewed sagittally. Thin layers of cells cap the apical surface of the biofilm and enclose the top of transport channels. The inferior portion of the channels remains open to the underlying substrate. A representative view of the section position through the centre of the colony is presented (top left). (b) A schematic proposing nutrient and oxygen gradients through the depth of biofilm transport channels. A thin layer of apical cells seals the top of channels and maintains a strict oxygen gradient, while nutrients and free oxygen can diffuse from the basolateral surface through open channel conduits into the biomass.

First senior-author paper is out today in the Journal of Microscopy! 🧪🔬 We present the first 3D printed microscope where both the optics & frame are entirely 3D printed - a low-cost, accessible, and reproducible tool for histological imaging! onlinelibrary.wiley.com/doi/full/10.1111/jmi.13398
An exploded view of the 3D-printed microscope. A front-facing (A), oblique (B), and side-facing view (C) of the microscope are presented, with the chassis coloured in grey and the positions of additional components highlighted with different colours (orange = LED light source, magenta = 3D-printed condenser lens, blue = 3D-printed objective lens, green = CMOS camera). A scale bar is presented in (a) to provide a visualisation of the size of the microscope setup.
