Gold Nanoparticles Coated with Semi-Fluorinated Oligo(ethylene glycol) Produce Sub-100 nm Nanoparticle Vesicles without Templates
摘要:
Gold nanoparticles (NPs) with diameters of 5, 10, and 20 nm coated with semifluorinated oligo(ethylene glycol) ligands were formed into sub-100 nm hollow NP assemblies (NP vesicles) in THF without the use of a template. The NP vesicles maintained their structure even after the solvent was changed from THF to other solvents such as butanol or CH2Cl2. NMR analyses indicated that the fluorinated ligands are bundled on the NPs and that the solvophobic feature of the fluorinated bundles is the driving force for NP assembly. The formed NP vesicles were surface-enhanced Raman scattering-active capsules.

Provided is a hollow particle aggregate formed by aggregating a plurality of self-organizable particles, wherein a metal core is modified by a surface modifier for a metal core comprising a first segment comprising an optionally branched fluorinated alkylene glycol group, an optionally branched fluorinated alkylene group, or an optionally branched fluorinated azaalkylene group; a second segment comprising at least one hydrophilic group and bonding to one of the ends of a main chain of the first segment; and a functional group that bonds directly or indirectly to the another end of the main chain of the first segment and is able to bond to the metal core.
