摘要: We introduce a mechanical approach to phase transfer of PEGylated gold nanorods. Amphiphilic PEG ligands can be switched between hydrophilic and hydrophobic states by applying force. PEG-GNRs in their state self-assemble into rings, phenomenon previously observed only for GNRs capped with ligands.
