3D dynamic imaging of soft materials
This schematic of a graphene liquid cell
shows multiple liquid pockets containing
single nanoparticles, dimers composed of
dsDNA bridges in different lengths, and
trimers.
In a new study led by DOE's Berkeley Lab, transmission electron microscopy (TEM) and a unique graphene liquid cell were used to record three-dimensional motions of DNA connected to gold nanocrystals. This is the first reported use of TEM for 3D dynamic imaging of so-called “soft materials,” a category that includes DNA, proteins and other biological compounds, plastics, therapeutic drugs, flexible electronics, and certain types of photovoltaics.
