  P-systems are abstract computational models inspired by the phospholipid
bilayer membranes generated by biological cells. Illustrated here is a
mechanism by which recursive liposome structures (multivesicular liposomes) may
be experimentally produced through electroformation of
dipalmitoylphosphatidylcholine (DOPC) films for use in `real' P-systems. We
first present the electroformation protocol and microscopic characterisation of
incident liposomes towards estimating the size of computing elements, level of
internal compartment recursion, fault tolerance and stability. Following, we
demonstrate multiple routes towards embedding symbols, namely modification of
swelling solutions, passive diffusion and microinjection. Finally, we discuss
how computing devices based on P-systems can be produced and their current
limitations.
