a) Schematic illustration of the procedures for positively charged CPNPs fabrication. b) Ligand dependent (with different carbon tail length noted as R12, R14, R16 and R18 respectively) fluorescence emission spectra of positively charged CPNPs. The black line shows the control CPNPs prepared without the ligand molecule, propylene glycol amine cationic lipid. c) The DLS, ξ potential and fluorescence QY of the CPNPs as noted in figure b).
