a The fabrication of RLMNPs in an ethanol solution via ultrasonication; (b) Photograph and the TEM image of RLMNPs; (c) Intensity-based size distribution histograms of RLMNPs measured by DLS; (d) Elemental mapping of RLMNPs, including Ga, In, O, P and S elements; (e) Zeta potential of liquid metal nanoparticles (LMNPs), RAFT agents and RLMNPs; Data were expressed as means ± SD. Error bars indicated standard deviations for 3 independent LMNP nanoparticle solutions; (f) UV-vis spectra, and (g) FTIR spectra of LMNPs, RAFT agents and RLMNPs.
