Everything from a single source, everything “Made in Germany”

At QubeDot, we take pride in the fact that our microLEDs are completely “Made in Germany”. From development and design to the manufacturing of our customized microLEDs, we offer the highest quality and innovation at every step.

But we go even further: Our microLEDs are also utilized in our microscopy solutions.

QubeDot’s digital microscopes are equipped with the most advanced technologies, such as brightfield, phase contrast, digital holography, and fluorescence, as well as custom features. We provide tailored solutions for your specific applications. Our devices offer a compact, portable design (footprint 15×15 cm²), integrated heating, a “One-Click-to-Image” Approach, modularity, and a customized software design with counting, autofocus, object detection and tracking.

Everything from a single source, everything “Made in Germany”.

SMILE®-platform used for optogenetics

In close collaboration with the Institute of Quantum Optics (IQO) in Hannover, we were able to demonstrate for the first time that biological cells could be excited using our SMILE®-platform.

In the lab of Prof. Alexander Heisterkamp at NIFE (Niedersächsisches Zentrum für Biomedizintechnik, Implantatforschung und Entwicklung), Dr. Maria Leilani Torres and their team employ fluorescence imaging to visualize calcium fluctuations in living cells.

The cardiomyocytes express a light-sensitive protein called ChR2. The cells were stained with calcium-sensitive dye and are activated when illuminated by SMILE®-platform. The spontaneous electrical activity can be overridden by the illumination pattern.

Using our SMILE®-platform, cell cultures can be stimulated by different illumination patterns.

We are very proud that our microLED platform simplifies research by providing a compact and easy-to-use light source for targeted stimulation of cells with minimal adjustment required compared to other optical systems.
