I have various bimetallic nanoparticles which have formed alloys. I then used NTA and TEM to characterize the size of my nanoparticles. The TEM shows that the size of nanoparticles is considerably less than the NTA. Can anybody help explain the difference in size?

  • $\begingroup$ not very confident but by looking at the Stokes-einstein equation would i be correct to say that if the viscosity is too low this could lead to a larger particles being reported? $\endgroup$ – The Free Radical Mar 14 at 18:04
  • $\begingroup$ Do you use similar controls in both (as in, partciles of known size)? $\endgroup$ – Buck Thorn Mar 14 at 19:19
  • $\begingroup$ TEM is a direct method. So, what assumptions come with the other technique? $\endgroup$ – Jon Custer Mar 14 at 21:33
