Formation of DNA-protein cross-links involving the initial formation of a guanine radical cation was investigated. For this purpose, riboflavin-mediated photosensitization of a TGT oligonucleotide in aerated aqueous solution in the presence of the KKK tripeptide was performed. We have shown

Polycationic polymers have been used to condense therapeutic DNA into submicron particles, offering protection from shear-induced or enzymatic degradation. However, the spontaneous nature of this self-assembly process gives rise to the formation of multimolecular aggregates, resulting in significant polyplex heterogeneity.

Single-strand oligo-DNA-modified Au nanoparticles (AuNPs) undergo aggregation in the presence of poly(L-lysine) (PLL), which is attributed to the interactions between the oligo-DNA and PLL. These interactions between the oligo-DNA and PLL were identified to be electrostatic when the lysine residues
