Fig. 3From: Recombinant protein embedded liposome on gold nanoparticle based on LSPR method to detect Corona virusOptimization of Au@R/Li. A Schematic image of citrated-coated AuNPs and POPC. B Transmission Electron Microscope (TEM) images and magnification of AuNPs and (C) Au@Li (scale bars = 20 nm; inset scale bars = 10 nm). D DLS size distribution depending on sonication time and the extrusion of AuNPs, Au@Li and Au@R/Li. E Surface zeta potentials of AuNPs, Au@Li and Au@R/Li in PBS. F Fourier transform infrared spectra of AuNPs, Au@Li and Au@R/Li. G Absorbance spectra of AuNPs, Au@Li and Au@R/LiBack to article page
