MINFLUX allows an everyday 3D resolution of 2 – 3 nm and offers about 100 times faster tracking than with a camera-based system.

Prokaryotes, comprising bacteria and archaea, are generally smaller than eukaryotic cells, but can be visualized with diffraction-limited microscopy. Many of their subcellular structures, however, lie beyond its resolving power. The same applies to the details of host-pathogen interactions. Protozoa, algae, and fungal cells, on the other hand, can be easily imaged with a conventional light microscope, but also here the detection of smaller details is hampered by the diffraction limit of light. Today, superresolution microscopy opens up completely new opportunities in microbiology.

abberior’s STED provides resolution down to 20 nm in 2D and 75 nm in 3D, and MINFLUX takes it another step further with single-digit nanometer resolution and molecular tracking at frequencies up to 10 kHz. It has been used, for example, to map the movement of individual ribosomes inside a bacterial cell. Add abberior’s fluorescent dyes and labels optimized for applications from confocal to MINFLUX, and you are ideally equipped to make your microbiological imaging experiments a success.

Microscopy for microbes

Microbial organisms come along in countless shapes and with highly diverse cellular architecture. Confocal and superresolution imaging colorfully captures this variety of cellular life. These bacteria were stained for DNA (green) and membranes (magenta) and imaged with STED.

From blurs to brilliance –

superresolution for microbiology

abberior microscopes facilitate superb imaging. Their optics, developed for the high demands of superresolution STED, also bring confocal imaging to a new level. On top of confocal and STED microscopes, abberior is the only commercial provider of MINFLUX, which achieves single-digit nanometer localization precision. Shown is a 2D MINFLUX image of Y. enterocolitica sorting platform protein Halo-YscL.

The sample was kindly provided by Alexander Carsten and Martin Aepfelbacher, Institute of Medical Microbiology, Virology and Hygiene, University Medical Center Hamburg Eppendorf, Germany.

Choose a superpower for your experiment – our modules

We offer many modules to overcome the specific imaging challenges in your research. Use TIMEBOW to separate signals in the same spectral channel by their fluorescent lifetime, extending your options for multicolor imaging. FLEXPOSURE adaptive illumination puts light only where it has an effect and may reduce the light burden by orders of magnitude, keeping your cells happy during extended live cell imaging and volume scans. RAINBOW detection allows you to  collect both maximum signal and extend spectral flexibility. Our modules can do all of this and even more! And if you can’t find what you need on our website, get in touch with us, and we’ll develop it for you.

Superresolution for biology: when size, time, and context matter

Superresolution for biology: when size, time, and context matter

The spatial resolution achievable with today’s light microscopes has unveiled life at the scale of individual molecules. Size is no longer a barrier to seeing biology at the most fundamental level. But life is not static. It emerges from movement and change. How do superresolution technologies hold up to the challenges of documenting dynamic biological mechanisms? Details >

How does a superresolution microscope fit in a shoebox?

A sleek, black-and-orange box transforms your widefield microscope into a confocal and a superresolution STED instrument and your exploration of subcellular structures into a seamless, discovery-rich experience. Carefully designed with masterly engineering, STEDYCON breaks the stereotype of the finicky, hard-to-use scope. It opens new possibilities at the press of a button for any user and almost any location. How does it do it? The secret’s in the box. Details >

Are you surprised that the very nature of light caps the resolution that we can achieve in microscope images? Luckily, there are workarounds to this limit. These workarounds push the amount of detail in an image by manipulating precisely where and when fluorophores are allowed to emit. As such, they provide us with a completely new set of tools to shrink the distance between two points while still being able to resolve them. Details >
