+                              <p>The primary ingredient, 4A3-SC8 or MC3, are ionizable cationic lipids that forms the core of the LNP. Ionizable cationic lipids become positively charged in acidic environments, such as when a pH change occurs for example in acidic buffers or in the endosome. This allows them to bind to negatively charged nucleic acids and form protective capsules around it. In the endosome these lipids facilitate endosomal escape through electrostatic interactions between the LNPs and the endosomal or cellular membranes.</p>

It plays a crucial role in binding to the negatively charged surface of lung epithelial cells. This enhances transfection efficiency and helps make the LNP formulation more lung-specific, improving targeted delivery. The neutral helper lipid DOPE (Dioleoylphosphatidylethanolamine) enhances endosomal escape by fusing with the endosomal membrane and improves transfection efficiency.</p>

+                            <p>Our LNP can be formulated using various methods depending on the scale of production, including pipette mixing, vortex mixing, or microfluidic mixing. After mixing the lipids with mRNA in carefully controlled ratios, the mixture is typically dialyzed to remove organic solvents like ethanol and citrate buffer. The choice of lipid composition and preparation method influences the tissue-targeting capabilities of the LNPs, allowing for selective delivery to organs like the liver, lungs, or spleen. For more detailed information on formulation methods and lipid selection, refer to our LNP Handbook deigned in cooperation with iGEM Team Linköping and others.</p>

         In our S2 laboratory, the harvested nasal epithelial cells that serve as primary cultures undergo a comprehensive HHH test (link zu primär Kulturen) to ensure their safety and suitability for further experiments. This test is crucial to ensure that we can subsequently work safely with these cells in the S1 range without the risk of contamination or unwanted release of biological material.

But although a well-developed hygiene concept is already existing, strategic development and a step-by-step approach are needed. In particular, the step-by-step implementation was emphasized, like starting with equipping the toilets. Bureaucratic hurdles, such as the need to apply to the rectorate, were identified as a major challenge. In addition, it became clear that there is a great need for sanitary facilities and facilities for the disabled, especially due to the needs of students and staff with health problems. Interaction and networking with other universities was also considered valuable. </p>],
     implementation: [<p>The next phase of developing a new hygiene concept is to maintain contact with Mr. Johannfunke in order to continue to advance the hygiene concept in collaboration. The strategic approach entails the incremental implementation of measures, exemplified by the establishment of the inaugural toilet facility within the main building. It is of the utmost importance to ensure the uninterrupted implementation of the hygiene concept. In order to achieve this, it is essential to draw upon the existing plans and measures that have already been implemented in new buildings.  We are working on advancing the plans at a higher level and are in regular dialogue with the Central contact point Barrier-free in order to overcome bureaucratic hurdles and actively promote the topic. Furthermore, it is necessary to intensify lobbying work in order to gain greater support for this issue at both the university and political levels. </p>],
