6 Conclusions
To explain the results obtained, a phenomenological model is offered which takes
into account the peculiarities of the molecular structure of star-like Dextran-graftPolyacrylamide copolymer with incorporated Au nanoparticles. It has been shown
that adding of the photosensitizer has almost no effect on the processes in ternary
nanosystem Polymer/AuNPs/Ce6 during irradiation. Under illumination with light
with λ irr = 650 nm, the variation of n is observed mainly in the small volume of the
