We’ve come a long way from the first glass-and-light optical microscopes. These days, scientists can focus on individual molecules using advanced methods like atomic force microscopy (AFM), where a miniscule probe feels out the details of a surface. And in this AFM image of a nanographene molecule, the resolution is so high that for the first time, we can see the individual bonds between atoms, shown here as green lines.
In a new paper in the journal Science, IBM researchers used the same imaging technique to measure the length and relative strength of individual bonds in the spherical carbon molecules called buckyballs. Their method can not only improve our intimate understanding of these and other molecules—it also lets us get up close and personal with the building blocks of all matter.
