We are part of nature

We develop highly sustainable systems and methods for analysis of samples to discover and promote the powerful networks of nature. Nature with its forces (earth, wind, fire, water, and love) is much, much, much (infinitely much) stronger than us, so we treat nature with respect. We eagerly explore natural systems to better understand their power.

• Is the better future based on regional natural foods, spices and botanicals produced bio-dynamically respecting nature or on tailored food products mainly based on highly processed powders, formulations and chemicals bought on the global market?
• Are personal care products necessary or is it better to avoid these and let the skin do the job? Avoid washing, rinse-off and cleansing products with many chemicals that dry out the skin and disturb the microflora of the skin.
• Are commodities and packaging really safe or are chemicals leaking or migrating into the products?
• How contamined are environmental samples? How can we avoid to contaminate the environment or waste water? Finally, we can find it in the surface and then drinking water. Prevention and precaution is the target.

A powerful analytical strategy is key to provide proof for proactive decisions.

Personally, you have the power to be part of the change we need. Change management starts at home by setting the own priorities. Start living in harmony and agreement with nature - happiness needs nature and minimalism. Back to the essentials. Be aware of pink bubbles and the art of advertisment, generating artificial personal needs - all professions are eager to do a good job. But nature is more important. Buy less but more truely sustainable (not green-washed) goods - at the end you have the same expenses. Eat less but sustainably produced food - at the end you have the same expenses. In Giessen, we have a marvelous food market on WED and SAT morning, where you can buy saisonal foods from regional farmers (no packaging included).

International Symposium on HPTLC 2024

Every two years the International Scientific Committee on HPTLC organizes the International Symposium on HPTLC:
Join the HPTLC 2024 to learn more and meet the worldwide HPTLC experts.

Built your open-source 2LabsToGo system 2.-7.09.2024

The latest system (we will publish soon) has an integrated autosampler, a nebulizer, mini-incubator, UV/Vis/FLD/bioluminescence detection including reflectance and backlight illumination and many further improvements. In advance, we will order (latest bill of materials, payment by installments possible upon request) and 3D print all parts for you. This means you can directly start at the workshop to mount yourself your system, whereby we will guide you. Some reading: Non-target screening of complex samples for hazards.

Schedule 2LabsToGo (1 h lunch break each; coffee at any time in between):

• MON 13:00-19:00 Assembly day 1
• TUE  08:00-18:30 Assembly day 2
• Wed  08:00-18:30 Assembly day 3
• THU  08:00-18:30 Finalization and operational qualification
• FRI   08:00-18:30 Applications: HPTLC-UV/Vis/FLD analysis of complex samples detected with planar Aliivibrio fischeri and pSOS-Umu-C-Vis/FLD
• SAT  08:00-13:00 Trouble shooting information for self-empowerment to be autarc

The miniaturised open-source 2LabsToGo system combines the functions of devices in two fully equipped laboratories: it covers all steps of high-performance thin-layer chromatography (chromatography laboratory) and planar bioassay detection (biological assay laboratory). The 2LabsToGo is an open-source all-in-one system that is compact (35 cm x 45 cm x 35 cm) and portable (8 kg). In addition, the system can be optionally equipped with solar panels. This means that the 2LabsToGo can also be used in the field to analyse complex samples. As the Lean Lab of the Future, it has a smaller ecological footprint in terms of material consumption, lower power consumption and significantly lower investment costs compared to two fully equipped laboratories. The do-it-yourself 2LabsToGo (3600 Euro material prize) was developed by us over the last decade. Funding of one PhD position was thankfully obtained via the Bundesamt für Ausrüstung, Informationstechnik und Nutzung der Bundeswehr grant E/U2AD/KA018/IF565 to be used in the container laboratory for food control missions abroad. The non-target biological detection is very helpful to detect any detrimental effects. This latest system is meant to be spread around the world. It also meant for self-empowerment.

Remark: Over two years (2011-2012), I asked (begged) many times the manufacturers of HPTLC devices to get involved in this project and collaborate to develop a low-cost small-scale system, but they refused and replied that I could do it myself. Alone it was the very hard way. It was most difficult to find persons with skills for coding or system engineers. In Germany, such skills are not available on the free market. With huge effort some M.Sc. students were willing, but contributed only 1.3 years on average in this project (poaching market). After the onboarding process, there were only a few months left to make real contributions to the project. To obtain funding was also challenging. We are very grateful that we have persevered under these circumstances. Now it is time to spread the latest system (which fulfills all needs) around the world.

Open-source means useable for everybody!

2LabsToGo at Analytica

Full days at Analytica2024: Three times a day the 1-h Live Lab presentation/moderation (0:26) and an oral presentation every day (Forum, Conference, DGF), a poster presentation and two interviews. Happily, I met my former guest researcher Hanna Nikolaichuk. I asked her if she could present the 2LabsToGo at the Live Lab during my two parallel morning lectures. Of the 12 Live Lab presentations, your two presentations were definitely the coolest! Many, many thanks to Hanna!!!

Great interest in our research

I got a call from Guido Deußing saying proudly Thank you because his interview with me in the journal Laborpraxis attracted the most interest by far in 2023 and has done so for years: Genotoxische Verbindungen sicher und effizient in Nahrungsmitteln bestimmen - Gesund ungesund: Erbgutschädigende Pflanzenöle?, Laborpraxis 7-8 (2023) 48-51

Each end of February: Join our course on planar bioassays

Cover image: Tomato products were screened with a ten-dimensional hyphenation with integrated simulated gastrointestinal digestion. Non-digested and digested samples were compared side by side. In their effect-directed profiles, 14 bioactive compounds from classes of lipids, plant hormones, spices, and pesticides were identified. The innovative hyphenation allowed for a non-target proactive food safety analysis. (From: Schreiner, T., Eggerstorfer, N.M. & Morlock, G.E.

All the best for New Year!

^{Wenn's alte Jahr erfolgreich war, dann freue dich aufs neue.
Und war es schlecht, ja dann erst recht.
Albert Einstein}

...ist eben Einstein!
Kann nicht jeder Tag, sogar jeder Gedanke, ein neuer Anfang zum Guten sein?

Unter den großen Persönlichkeiten, die an der JLU geforscht, gelehrt und studiert haben, befindet sich nicht Einstein, aber Justus Liebig, Wilhelm Conrad Röntgen (Nobelpreis für Physik 1901), Wangari Maathai (Friedensnobelpreis 2004), Volker Bouffier, Frank-Walter Steinmeier und viele mehr.
