Nanoporous Silica-Based Protocells at Multiple Scales for Designs of Life and Nanomedicine [PDF]
Life, 2015 Various protocell models have been constructed de novo with the bottom-up approach. Here we describe a silica-based protocell composed of a nanoporous amorphous silica core encapsulated within a lipid bilayer built by self-assembly that provides for ...

Multistable Protocells Can Aid the Evolution of Prebiotic Autocatalytic Sets [PDF]
Life, 2023 We present a simple mathematical model that captures the evolutionary capabilities of a prebiotic compartment or protocell. In the model, the protocell contains an autocatalytic set whose chemical dynamics is coupled to the growth–division dynamics of ...

A model of protocell based on the introduction of a semi-permeable membrane in a stochastic model of catalytic reaction networks [PDF]
Electronic Proceedings in Theoretical Computer Science, 2013 In this work we introduce some preliminary analyses on the role of a semi-permeable membrane in the dynamics of a stochastic model of catalytic reaction sets (CRSs) of molecules. The results of the simulations performed on ensembles of randomly generated

Sustainable Growth and Synchronization in Protocell Models
Life, 2019 The growth of a population of protocells requires that the two key processes of replication of the protogenetic material and reproduction of the whole protocell take place at the same rate.

Models of Protocells Undergoing Asymmetrical Division [PDF]
EntropyThe conditions that allow for the sustained growth of a protocell population are investigated in the case of asymmetrical division. The results are compared to those of previous studies concerning models of symmetrical division, where synchronization ...
