Now, a team led by Bryan Shaw at Baylor University in the USA have made inexpensive bite-size models of proteins that can be visualized using the mouth (Baumer, K. M. et al. Sci. Adv. 7, eabh0691 (2021)). Models of nine globular proteins were prepared in two different sizes (pictured); the smaller set ranged from 2–10 mm and the slightly larger set from 5–20 mm. The models were either made from edible gelatin (the same substance that gummy bears are made from) using custom food-grade silicone molds or 3D-printed from non-edible biocompatible resin; in each case, the protein structures were derived from the Protein Data Bank. The non-edible models were prepared with an eyelet so that a safety loop could be added to prevent them from being swallowed.
