Transmission electron microscopy (TEM) uses a focused beam of electrons to image a sample by transmitting the beam through it. Recent work has used TEM to investigate the temperature dependence of the structure of graphene oxide, focusing in particular on the placement of the oxygen atoms around the carbon lattice.

Raman and infrared spectroscopy are highly complementary analytical tools that are sensitive to the vibrational modes of molecular species or materials. Understanding the behavior of microplastics means being able to characterize their dimensions as particles and also evaluate their chemical composition. Raman spectroscopy and Fourier Transform infrared (FTIR) have successfully been used to characterize some particles from environmental samples.
