Embedding of fluorescent dyes into polyelectrolyte capsules for remote destruction of the capsule shell by laser irradiation

Polyelectrolyte capsules were modified by different types of fluorescent dyes and their optical properties were investigated. Three methods of encapsulation were used: dye adsorption onto the porous core, change of the solvent and embedding into the polyelectrolyte shell. Suspension of capsules with Rhodamine 6G molecules in the shell was irradiated by laser beam with wavelength corresponded with the absorption band for the dye molecule. Measurements of the capsules size distribution before and after laser irradiation showed that the capsules were destroyed by laser radiation.
