Cytoplasmic streaming could be employed for the transportation
of bio-compatible substances inside the protoplasmic network. In
[7] we demonstrated that the plasmodium of P. polycephalum con-
sumes various colored dyes and distributes them in its protoplasmic
network. By specifically arranging a configuration of attractive
(sources of nutrients) and repelling (sodium chloride crystals) fields
we can program the plasmodium to implement the following
operations: to take in specific colored dyes from the closest colored
oat flake; to mix two different colors to produce a third color; and, to
transport color to a specified locus of an experimental substrate.
Inspired by our previous results and studies on cellular endocy-
tosis of magnetic nano-beads and fluorescent nano-beads ,
and intake of latex beads by the amoeba’s endocytotic mechanisms , we undertook experiments on the intake of magnetite nano-
particles and glass micro-spheres coated with silver metal by Phy-
sarum . We found that the slime mold can propagate the
nanoscale objects using a number of distinct mechanisms, includ-
ing endocytosis, transcytoses and dragging.
