• presence of transfection agents, suggesting that the altered charge pattern of the oligonucleotide backbone enabled its cellular self-delivery [44]. The same authors then also studied similar oligonucleotides with guanidinium groups as cationic moieties, which were obtained by postsynthetic guanidinylation

To meet the prerequisites for self-delivery systems, besides biodegradability, the hydrogelators should preserve the pharmacological efficacy of the therapeutic building blocks, any side effects should be minimized and the biocompatibility maximized. Therefore, a convenient
