Fig. 3. TEM micrographs depicting liquid metal nanomaterials stabilized with different positively-charged surfactants, including small molecule cetrimonium bromide (CTAB), synthetic polymer poly(4-vinyl-1-methyl-pyridinium bromide) (P4VMPB), and protein lysozyme (Lys). The particle morphology was the same for all three positively-charged surfactants. The scale bars are 100 nm.
