The secondary amphipathic peptide CADY forms stable positively charged nanoparticles with short interfering RNA (siRNA), which involves both electrostatic and hydrophobic interactions. CADY/siRNA self-assembling nanoparticles adopt a “raspberry”-like architecture cemented together by a matrix of free peptides. These nanoparticles are nontoxic and promote efficient delivery of siRNA in challenging primary cell lines.
