What are the Challenges in Weighing Nanoscale Materials?
One of the primary challenges in weighing nanoscale materials is their extremely small mass, which often falls into the range of picograms or even femtograms. This requires highly sensitive instruments and techniques. Another challenge is the aggregation of nanoparticles, which can result in erroneous weight measurements. Additionally, environmental factors such as humidity and temperature can affect the accuracy of these measurements.
