Chemistry – A European Journal, Volume 32, Issue 17, 5 May 2026.In this work, the synthesis and characterization of novel π‐extended phenazine diimides is reported. The derivatives undergo differential reduction to a dihydrophenazine or Meisenheimer form depending on the reaction conditions employed. The outcome of this work highlights the paramount importance of structural design in determining the nature of the ...

The reproduction process of Gram-positive protocells
Scientific ReportsProtocells are believed to have existed on early Earth prior to the emergence of prokaryotes. Due to their rudimentary nature, it is widely accepted that these protocells lacked intracellular mechanisms to regulate their reproduction, thereby relying ...

On RAF Sets and Autocatalytic Cycles in Random Reaction Networks
, 2014 The emergence of autocatalytic sets of molecules seems to have played an important role in the origin of life context. Although the possibility to reproduce this emergence in laboratory has received considerable attention, this is still far from being ...

Small Science, Volume 6, Issue 5, May 2026.Amine‐functionalized block copolymer nanoparticles were synthesized via RAFT‐PISA with rigorous quantification of interfacial amine accessibility. The surface‐reactive amines served as modular handles for postassembly conjugation with fluorescent dyes and thermoresponsive polymers, conferring optical trackability and stimuli‐responsive behaviors ...

On the Terminology of Lipid Nanoparticles, Liposomes, and Vesicles
ChemSystemsChem, Volume 8, Issue 3, May 2026.The terms “liposome,” “vesicle,” and “lipid nanoparticle” (LNP) should be defined clearly to avoid conceptual and practical errors. Structures and distinctions are introduced here for nonspecialists. Overly broad use of “LNP” to refer to any nanosized, lipid‐based assemblage is discouraged.

Multistable Protocells Can Aid the Evolution of Prebiotic Autocatalytic Sets
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 ...

Preliminary steps toward artificial protocell computation [PDF]
, 2007 Protocells are hypothesised as a transitional phase in the origin of life, prior to the evolution of fully functional prokaryotic cells. The work reported here is being done in the context of the PACE project, which is investigating the fabrication of ...
