Considering the different advantages and limitations of each microscopic technique, we show that when they are used together they can complement each other, ultimately providing more information about the dimensions of GO materials without significant bias. Combining all the microscopic techniques used in the present study (Figure ), we found that l-GO flakes had lateral dimensions varying between 1 and 30 µm, s-GO flakes ranged between 50 nm and 2 µm and us-GO flakes were smaller than 500 nm.
