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.

Funds for the QVLS-HTI in quantum technology

As a proud founding member of the QVLS e.V. (Quantum Valley Lower Saxony e.V.), we are very pleased about the funding from the state of Lower Saxony.

The so-called High-Tech Incubator (HTI) is intended to provide substantial support for the establishment of start-ups that rely on quantum technologies.

The possibilities of using quantum processes for pioneering technological innovations, e.g. in the field of computing, cryptography or sensor technology, are full of opportunities.

The next generation of µLED technologies

As part of the EU project SMILE in which we are proud to be a project partner, a new generation of µLED technology is being developed.

Professor J. Daniel Prades from the Universitat de Barcelona visited the Quantum Valley Lower Saxony (QVLS) at the Mobile World Congress in Barcelona and gave this exciting interview:

QubeDot at the CS International Conference in Brussels

Our team from QubeDot is very pleased to have been part of the CS International Conference in Brussels.

Jan, our CTO and Co-Founder of QubeDot, has given a talk about µLEDs for structured illumination and the versatility of our SMILE® Technology to address multiple markets.

µLEDs with dimensions of 1 to 50 µm are becoming increasingly interesting driven by the µLED revolution in display technology.

Our µLEDs are in addition also used – among other applications – in biology, optogenetics, microscopy and process metrology.

Do you want to know more about our customized µLEDs?

microLED-lines are very interesting

A glance at the portfolio of well-known suppliers of large, very powerful LEDs that emit on the order of several watts is enough to see that these LEDs are mostly round or square-shaped. But does that actually have to be the case? Doesn’t it make sense that LEDs could also be line-shaped for specific applications?

Some of our customers had also asked us this question. Of course, we don’t hesitate for long when it comes to such exciting questions. Our access to the clean room supports us in finding the appropriate answer within the shortest possible time. The answer to the question is „YES“ – twice.

Yes, it can sometimes make sense to use linear microLEDs as well.

Yes, we can produce microLED lines.

The picture shows a microLED line with a width of 10µm and a length of 1000µm. Of course, processed on GaN wafers – because that is our expertise!

QubeDot is founding member of the QVLS e.V.

Our µLED technology also plays an essential role in the development of quantum computers.
For this reason, we have been honored to be a founding member of QVLS e.V. together with renowned partners. After an intensive period of efficient preparation, the QVLS e.V. will go „live“ on February 10, 2021 with a digital launch event – accompanied, among others, by the Minister for Science and Culture of Lower Saxony Björn Thümler.

We wish the association all the best for the future!

New housing for SMILE platform

Our µLED arrays are the key to our Structured Micro Illumination Light Engine (SMILE) platform. They enable as a complete system the precise control of every single light pattern.

MicroLED array with 16×16 pixels in new star housing – connected to USB and ready to illuminate your samples.

The new housing allows for an easy integration of the SMILE platform into optical system as it is compatible to 60mm cage systems and offers additional threads.
