What is the primary impact of engineering a microscope capable of near-atomic resolution *in vivo*?

It would revolutionize biology and medicine.

Many necessary inventions are not end-user applications themselves but rather fundamental scientific tools that act as force multipliers, opening pathways to countless other discoveries. One such critical tool involves engineering a microscope with extreme capabilities: it must be both incredibly powerful and perfectly safe for use on living subjects. Specifically, this instrument needs to achieve imaging resolution at near-atomic levels while observing biological processes *in vivo* (within a living organism). The successful creation of such a microscope is projected to cause a revolutionary transformation across the fields of biology and medicine by allowing unprecedented observation of dynamic life processes at their fundamental scale.
