Introducing atomic-scale defects and holes in 2D materials changes their 
electrical and optical properties. When 2D materials are suspended, 
vacancies make the membranes permeable to ions and molecules in liquid 
or gas phases, allowing transport studies at atomic scales. Atomic 
defects can also be interesting ingredients in quantum devices such as 
defects and holes in 2D boron nitride and 2D ferromagnets. Angstrom-size 
holes can also allow the passage of water molecules but block the larger 
hydrated salt ions and can effectively desalinate water. Raman peak 
shifts combined with TEM, provide a comprehensive approach to 
characterize the holes and transport through them. When molecules are 
driven through 2D nanopores in solution, they can perturb the ion 
current flow through the pore, from which molecule’s physical and 
chemical properties can be inferred. DNA other biomolecules can be 
detected in this way. Thanks to advanced materials, device designs and 
custom electronics, the temporal and spatial resolution for their 
detection has been rapidly improving. This interdisciplinary work 
advances several disciplines including in situ electron microscopy.
