Transmission electron microscopy (TEM) images of grafted PCL-b-POEGMA on silica nanoparticles (SiO2 NPs)

In this project, both room temperature and cryogenic transmission electron microscopy (TEM) samples were made and inserted into TEM instrument. TEM images of the grafted nanoparticles (NPs) listed are shown individually to exhibit the polymer band around the surface of the NP. TEM images of aggregated NP species were used to measure brush length of the polymers attached to the NPs.
