Fig. 1 “Small” and “smaller” molecular models: Highly portable and encodable with flavor. (A) Smaller nonedible 3D-printed models of calmodulin (CaM) and carbonic anhydrase II (CA II) are comparable in size to a popcorn kernel or grain of rice. Array of protein models fabricated and tested in this study from (B) biocompatible resin (top: small size; bottom: smaller size) or (C) gelatin (flavor-coded or uncoded). (D) Small nonedible model with a safety lanyard threaded through the integral eyelet. (E to G) Smaller nonedible models can be coded with flavor and transported in high volume. (E) Shrink-wrapped array onto a standard index card and (F and G) packed into common containers of candy (shown for demonstration purposes). Photo credit: Jordan C. Koone, Baylor University; Bryan F.
