(1) The synthesized low-molecular-weight polymer
PDMAEM is a stabilizer of amorphous selenium
nanoparticles. The water-soluble nanocomplex
PDMAEM–nano-Se0 formed in the process can be used
for selenium intercalation in an Acetobacter xylinum
cellulose gel film.

(2) The optimal sorption parameters for stabilization
of the amorphous form of selenium in the gel film are as
follows: temperature 20–25°С, sorption time 30–40 min,
and selenium concentration in the initial solution сSe
=
0.005–0.05%.
(3) Upon intercalation of PDMAEM–nano-Se0 into
the gel film, as in the case of intercalation of PVP–nano-
Se0, the structural characteristics of the film remain
unchanged.
