Schematic representation of the AuP NPs biofunctionalization, ceragenin (CSA) immobilization and labelling of AuP@CSA-131 with IRDye® 800CW (A). STEM image of the obtained AuP NPs (B1) and SEAD patterns of gold nanoparticles used for nanosystem synthesis (B2). Unenhanced FT-Raman spectra of MHDA (black spectrum), CSA-131 immobilized on the AuP NPs surface (red spectrum) and CSA-131 immobilized on the AuP NPs surface marked with IRDye® 800CW (green spectrum) (C). TGA data of AuP@CSA-131 (D) and AuP@CSA-131 (800CW) (E) showing the solvent removal and decomposition of the product.
