Work on producing an artificial protein cage (called TRAP-cage) combined with gold nanoparticles (features in our previous news report: https://tinyurl.com/7v4bpp9w). The researchers, working with international partners, were able to show that an artificial protein cage structure was able to precisely arrange gold nanoparticles in three dimensions.

The paper was published in Nano Letters and can be accessed here: https://pubs.acs.org/doi/10.1021/acs.nanolett.1c04222
