75 mg of EGaIn was added in 15 mL of ethanol and put in the ice bath for 30 min to cool down. Afterward, the EGaIn solution was sonicated under an ice bath for 25 min (30% power, Sonics VCX-750 Vibra Cell Ultra Sonic Processor equipped with a 6 mm sonication probe). After sonication, the mixture was regarded as the LMNPs solution.
50 mg of RAFT and 75 mg of EGaIn were mixed in 15 mL of ethanol and put in the ice bath for 30 min to cool down. Afterward, the EGaIn solution was sonicated under an ice bath for 25 min. The supernatant was collected to measure the efficiency of RAFT agent attachment to the surface of LMNPs. The precipitation was collected and dispersed into the solution by water bath sonication to achieve RLMNPs solution.
