1. The molecule of the polymer carrier of the formula (I): LPS- [SPS] -SPL, in which the components P and P are different or identical to each other and represent a linear or branched chain hydrophilic polymer, each of the components P and P represents at least one -SH- the part of the molecule capable of forming a disulfide bond upon condensation with component P, a linear or branched chain hydrophilic polymer selected independently from each other from polyethylene glycol (PEG), poly-N- (2-hydroxypropyl) methacrylamide, poly-2- (methacryloyloxy) ethylphospho ilcholines, poly (hydroxyalkyl-L-asparagine), poly (2- (methacryloyloxy) ethylphosphorylcholine), hydroxyethyl starch or poly (hydroxyalkyl-L-glutamine), wherein the hydrophilic polymer chain has a molecular weight of from about 1 kDa to about 100 kDa. Cationic or a polycationic peptide or protein with a length of from about 3 to about 100 amino acids, or a cationic or polycationic polymer with a molecular weight of from about 0.5 kDa to about 30 kDa, each P represents at least two -SH moieties capable of forming a disul f-bond when condensed with additional Riley components, Ri / or P component (s)； -SS- is a (reversible) disulfide bond； L is an optional ligand that can be present or absent, and can be selected independently from other components from RGD, transferrin, folate, signal peptide or signal sequence, signal or sequence of nuclear localization, penetrating the cell peptide (PKP), TAT, receptor ligand, cytokines, hormones, growth factors, low molecular weight compounds1.
