Figure 2From: Preparation of ractopamine-tetraphenylborate complexed nanoparticles used as sensors to rapidly determine ractopamine residues in porkSEM and TEM images, and FTIR spectra. SEM images of the obtained RT NPs (a) and the surface of the modified electrode (c); TEM image of RT NPs (b); the insert is the size distribution measured by DLS. (d) FTIR of RT NPs, RAC, and TPB.Back to article page
