Confocal microscopy and fluorescence anisotropy for dye dynamics; magnetic field for ferrofluid-loaded vessels.

Main Results:

Successful preparation of water-filled polymer microvessels.
Demonstrated encapsulation of fluorescent (Rhodamine 6G), magnetic (ferrofluid), and ionic (Cu2+) species.
Rhodamine 6G showed reduced rotational dynamics due to polypyrrole interaction.
Ferrofluid-loaded microvessels exhibited magnetic responsiveness.
Cu2+-loaded microvessels functioned as transducer layers in ion-selective electrodes.

Conclusions:

Pyrrole photopolymerization in emulsion is an effective method for creating functional microvessels.
These microvessels offer versatile encapsulation and demonstrate potential in sensing and magnetic applications.
The study highlights the tunable properties and broad applicability of these novel polymer microstructures.
