This nanoshell model is a modified buckyball. Instead of using the standard 3 prong blue and black 120 degree trigonal atoms, 5 prong blue trigonal bipyramidal atoms and black trigonal bipyramidal atoms are used so that the outer sphere can be secured to the inner sphere. The blue atoms in this case represent gold since non of our trigonal atoms are grey or silver colour.
This article an interesting read & might help some understand how the mRNA vaccines work. The nanoparticles in mRNA vaccines are nothing to fear: We interact with many useful, tiny particles every day.
The inner black layer denotes a silica nanosphere while the outer blue layer represents gold. These compounds are used in cancer therapy or for tumor imaging.
