If you're wondering why keeping drugs from solidifying into crystals is such an issue, it's because drugs that are crystalline in shape do not get fully absorbed by the body, something that keeps them from optimal effectiveness. Unfortunately, this is difficult to prevent as solutions that evaporate while in contact with a physical vessel generally solidify into their crystalline forms.
To get around this, the scientists skipped out on the usage of traditional containers and used levitation by way of the acoustic levitator to form pristine samples that "can be probed in situ" with the high-energy X-ray beam at Argonne's Advanced Photon Source instead.
