Researchers have shown that two photons, seen here as waves (right and left), can connect a short distance apart. Under certain conditions, these photons can create a state similar to a diatomic molecule, a state shown by the shape of the blue dumbbell in the center of the movement. Figure: NIST

A transmission electron microscope (TEM) image of silver nanoparticles formed from silver ions in a solution containing humic acid. The acid tends to envelop the nanoparticle (visible in the image as a light background) and prevent it from accumulating together with other nanoparticles.
