Functionalized alternan polysaccharide, comprising nitrogen groups or permanently positively charged nitrogen groups that can be protonated as functional groups and can be described by the following formula, for instance: (I) wherein R
1
is a hydrocarbon group with 1 to about 100 carbon atoms, that may comprise one or more heteroatoms, R
2
and R
3
are each a hydrogen or a hydrocarbon group with 1 to about 20 carbon atoms that can comprise one or more heteroatoms, wherein R
2
and R
3
can be the same or different, or R
2
and R
3
form a 4-8 membered heterocyclic ring together with the nitrogen to which they are bound; Wherein said ring can be condensed with one or more additional isocyclic or heterocyclic rings, wherein the nitrogen can be bound to one of the R
2
or R
3
groups by way of a double bond and then bears a positive charge, wherein the nitrogen in Formula (I) is optionally protonated, and wherein the residues R
1
, R
2
and R
3
can be selected independently from each other in multiple —R
1
NR
2
R
3
groups.
