Electron microscopy water artefact, SEM C018 / 0557
Electron microscopy water artefact, coloured scanning electron micrograph (SEM). This is the surface of a compound eye from a bee. A compound eye consists of many rounded lenses known as ommatidia (hexagonal). The circular patterns (grey) are the result of not drying the sample correctly, resulting in evaporation of water from the surface of the ommatidia. Electron microscopy samples have to be dehydrated and then dried using critical point drying techniques to avoid this phenomenon. Magnification: x700 when printed at 10 centimetres across

EDITORS COMMENTS
This print showcases the intricate beauty of a compound eye from a bee, captured through electron microscopy. The compound eye is composed of numerous hexagonal lenses called ommatidia, each contributing to the bee's exceptional vision. However, upon closer inspection, circular patterns in grey can be observed on the surface of these lenses. These intriguing patterns are actually evaporation marks caused by improper sample preparation techniques during electron microscopy. In order to avoid this phenomenon, samples must undergo dehydration and critical point drying processes meticulously. This ensures that water does not evaporate from the surface of the ommatidia and distort their natural appearance. With a magnification level of x700 when printed at 10 centimeters across, this image allows us to appreciate the remarkable details present in nature's creations. It serves as a reminder of how even small organisms like bees possess complex anatomical structures that contribute to their survival and sensory capabilities. Through this photograph, we gain insight into entomology and zoology while marveling at the wonders found within our natural world. The vibrant colors add an artistic touch to scientific exploration, blurring boundaries between disciplines and inviting viewers to appreciate both aesthetic appeal and scientific significance simultaneously.
