Many properties of lipid membranes have been characterized over the past decades by all-atom models. Such properties include the area per lipid, order parameters, and density profiles for instance. Currently 100s of nanoseconds can be probed for membranes containing a few thousands of lipids.
However, for many membrane related processes more extensive sampling is required, either in the time domain or in terms of an increased system size to study collective events. In those cases the Martini model is a good alternative. Examples include the nucleation of gel domains in either pure  or mixed  lipid membranes (see figure), transition toward non-lamellar phases , partitioning of other compounds such as alcohols , voltage sensitive dyes , flip-flop of cholesterol [5,6] and tethered membranes [11,12].
Furthermore the Martini model can be efficiently used for systematic studies in which a large number of simulations need to be performed. For instance, the membrane area and thickness as a function of location of double bonds , or the self-diffusion of transmembrane peptides as a function of peptide sequence  have been systematically explored with Martini. Another application of Martini is in the in-silico design of membranes with controlled properties using e.g. bolalipids .
