Protocell life cycles

Reverse micelles

Reverse micelles are water-in-oil structures. The oil phase can be replaced by an apolar solvent. The envisioned reactions will take place in the aqueous medium or/and at the interface between the two solvents where amphiphiles and precursors are concentrated.

  • What are the properties reverse-micellar systems containing an amphiphile production systems?
  • Where do the chemicals reside in the multiphase systems?
  • What are the conditions for the photochemical reactions proceed efficiently?
  • What are the impacts of the internalized production of amphiphiles on the properties (size, shape, number) of the reverse-micelle population?
  • How can concerted life cycles (growth and division) be implemented in these structures?

Vesicles

Vesicles, which are aggregates with an internal aqueous volume surrounded by a bilayer structures forming the interface with the external aqueous medium, can grow and divide under the right conditions. The core of the photochemical reactions will take place at the interface of the amphiphile bilayers with the chemical reagents embedded in them.

  • What are the compositions of the bilayers that allow for the growth to take place? 
  • What is the kinetics of this process and its implication for the stability/integrity of the whole chemical system?
  • What are the compositions of the bilayers that allow for the division to take place? 
  • What is the kinetics of this process and its implication for the stability/integrity of the whole chemical system?
  • Study of the kinetics of both processes occurring sequentially
