    Recently there has been an explosion in the number of systems available for in-situliquid-phase electron microscopy (1). These systems separate the liquid from the vacuum andallow for nanoscale imaging as well as electrical contact. Such systems are important for the further development of nanotoxicological studies, battery research and catalysis. Here we present two unique systems for in-situ electron microscopy. The first system is amonolithic chip for Transmission Electron Microscopy(2) (Figure 1a). The proof-of-conceptsystem verified the ability to separate the liquid from the vacuum while imaging. Currentmanufacturing will include lower liquid volume and electrical contact.The second system is a peek holder with a microfabricated chip which allows for fullelectrochemical characterization in the Scanning Electron Microscope (3) (Figure 1b). The system has been used for in-situ electrochemistry and has achieved ~10 nm resolution. Such systems are important tools for developing sustainable technology and for understanding nanoscale phenomena. However, both systems suffer from interacting with theelectron beam, which is a high-voltage radiation source, and therefore initial experiments will necessarily have multiple reference experiments to ensure results can be made with negligible influence by the electron beam interaction.
