In total 15 head and 10 linker fragments were made along with 2 fragments for constructing PEGylated lipids. When combined with the available tail parameters, this setup allows for the generation of hundred of different lipids. As an example, we provided a total of 117 unique coarse-grained (CG) models of ILs, each in both neutral and charged states (total of 234 parameter files). Furthermore, additional IL models featuring branched tails were constructed, including the well-known ALC-0315 and SM-102, which are used in Pfizer and Moderna vaccines, respectively .
