“…Conceptually related to the classic ink-jet print head, pulse-jetting is also useful for the preparation of membranous compartments. [338,339] Pulse-jetting provides high control over lipid composition and spontaneous curvature, oriented membrane protein incorporation, and encapsulated contents. Kamiya et al [340] generated a jet flow interacting with an asymmetric planar bilayer, which produced elongated membranes that split into vesicles of two different sizes: 100-200 µm and 3-20 µm.…”

to assemble astonishing pieces of a complicated puzzle, and realized that further advancement requires input from multiple branches of science, not just biology as the primary life science. Detailed hypotheses have been established about the different scenarios of the emergence of life, including the "RNA world," [1] the "lipid world," [2] "replicator first," [3] "metabolism first," [4][5][6] and others. Although the origin of life is still surrounded by many open questions, our understanding of chemical, physicochemical, and biochemical processes possibly involved in the ancient events preceding Darwinian evolution has seen much progress. We have come a long way from Leduc's physicochemical, inorganic matter-centered view on the beginning of the evolution, yet the matter of the transition from nonliving to living matter still remains largely unsolved, and one of the great scientific problems of our time.The phylogenetic tree of different living domains reflects that life has evolved from simple to more complex structures, i.e., from single-to multicellular organisms. The oldest fossil evidence dating back 3.5 Gy (billion years) comes from stromatolites, [7][8][9][10] microorganismal residues in sedimentary rocks. [11] There appears to be a gap of knowledge regarding the period of evolution between the first primitive hypothetical cells and the fossilized ancient bacteria, which can be considered as an already advanced form of life. [12] It is highly likely that intermediate primitive cell precursors preceded the single-cell organisms. The hypothetical prebiotic structures that were the stepping stone to first self-sustaining living cells are commonly termed "protocells." The possibility of a strong link between the formation of protocells and the origin of life can today be reasonably assumed.One cannot easily proceed in the context of the evolution of cell-based organisms without briefly illuminating the concept of life as we know it on our planet. Over time, different requirements have been proposed for an entity to be considered alive. According to Tibor Ganti's chemoton model, [13] a protocell contains three autocatalytic subsystems: a membrane subsystem that keeps the components together and intact, a metabolic subsystem that captures energy and material resources, and an information subsystem that processes and transfers heritable information to progeny. To be considered alive, these subsystems must be unified and function co-operatively for the survival and evolution of the supersystem. Pohorille and Deamer suggested a modified set of 7 criteria related to the chemoton. [14] At about the same time, Oro defined the requirements by 10 characteristic features. [15] Despite their differences, these descriptions align well with NASA's broader definition of life: "a self-sustaining chemical system capable of Darwinian evolution."The origin of life is still one of humankind's great mysteries. At the transition between nonliving and living matter, protocells, initially featureless aggregates of abiotic matter, ga...
