“…Group I (100-250 cm −1 ) including peaks at 146, 171 and 201 cm −1 may come from the vibration modes by liberation and translation of the tetrahedral-octahedra chains in β-Ga 2 O 3 , consistent with the reported literature. 10,21 Group II (250-500 cm −1 ) involves three main peaks at 349, 419 and 476 cm −1 , respectively, corresponding to the inplane-correlated modes of GaO 6 octahedra. As for Group III (500-800 cm −1 ), peaks located at 634, 658 and 770 cm −1 are contributed from the optical modes related to GaO 4 octahedra.…”

“…[34] The peak at 910.27 cm −1 represents the in-plane bending peak for C-OH, [38] while the peak at 2404.97 cm −1 corresponds to the interference CO 2 in atmosphere. [39] After the modification of Au, all the peaks are smaller than EGaIn-PABA and EGaIn, indicating the Au was attached to the nanodroplets, as the carboxyl group on the surface and the functional groups on Ga 2 O 3 are relatively blocked.…”

Gallium‐based liquid metal systems hold vast potential in materials science. However, maximizing their possibilities is hindered by gallium's native oxide and interfacial functionalization. In this study, small‐molecule ligands are adopted as surfactants to modify the surface of eutectic gallium indium (EGaIn) nanoparticles and suppress oxidation. Different p‐aniline derivatives are explored. Next, the reduction of chloroanric acid (HAuCl4) onto these p‐aniline ligand modified EGaIn nanoparticles is investigated to produce gold‐decorated EGaIn nanosystems. It is found that by altering the concentrations of HAuCl4 or the p‐aniline ligand, the formation of gold nanoparticles (AuNPs) on EGaIn can be manipulated. The reduction of interfacial oxidation and presence of AuNPs enhances electrical conductivity, plasmonic performance, wettability, stability, and photothermal performance of all the p‐aniline derivative modified EGaIn. Of these, EGaIn nanoparticles covered with the ligand of p‐aminobenzoic acid offer the most evenly distributed AuNPs decoration and perfect elimination of gallium oxides, resulting in the augmented electrical conductivity, and highest wettability suitable for patterning, enhanced aqueous stability, and favorable photothermal properties. The proof‐of‐concept application in photothermal therapy of cancer cells demonstrates significantly enhanced photothermal conversion performance along with good biocompatibility. Due to such unique characteristics, the developed gold‐decorated EGaIn nanodroplets are expected to offer significant potential in precise medicine.
