Want to prepare a nice and clear to explain presentation on: TechBio modules, which includes 1) NTA (Nanoparticle Tracking Analysis); 2) NanoFACS; 3) TEM (Transmission Electron Microscopy) image; 4) Western Blot image analysis. The concept mainly revolve around Exosomes/Extracellular vessicle characterization. The developed modules should be complement to each other with certain identified parameters (If not is also fine).
