Stimulus-Responsive Release from Poly(ferrocenylsilane) Nanocontainers
Redox-responsive polyÂ(ferrocenylsilane)
(PFS) is used to construct
nanocontainers that can be loaded with hydrophobic cargo by a miniemulsion
approach. The resulting structures comprise a solid shell surrounding
a liquid oil core and have diameters of approximately 470 nm with
a shell thickness of ca. 29 nm. The electrochemical behavior of the
ferrocene group is investigated using cyclic voltammetry. Electrochemical
oxidation and the thereby caused change of container morphology are
shown. Hydrophobic molecules (Nile Red and 2-propylpyiridine) are
loaded into the nanocontainers and can be released upon oxidation
of the shell material. The oxidation is achieved chemically by the
addition of hydrogen peroxide or by the enzymatic oxidation of glucose
to release 2-propylpyridine over a period of time
