A significant gap remains in understanding the specific properties of viral capsids and the intercapsid interactions that govern their self-assembly into ordered structures, as opposed to random aggregation. Electrostatic attractions among nanocages can be tailored by adding charged component, such as polypeptides, dendrimers, nanoparticles, metal ions, or even coassembly with a different nanocage. The nanocage can further be precision bioengineered to obtain selected functional groups on their surface for inter-particle interactions. In addition to electrostatic forces, hydrophobic interactions can modify the resulting geometrical orientation of the aggregates. Aromatic stacking or coil-coil interaction through surface modification by covalently attached molecules, can guide assembly and diminish the dependence of the resulting structure on the nanocage's initial shape. This is also evident in cases where electrostatic templating of nanocages occurs before crosslinking, with the binding depending on the specific protein sequence. This work fills some of this knowledge gaps and reports the creation of suprastructured biomaterials from the Acinetobacter phage coat protein AP205 with pMETAC. AP205 is formed from 90 copies of AP205 dimers, assembling into an icosahedral geometry of a diameter of about 28 nm. The VLP has been studied and optimized for immunization and vaccine delivery. AP205 VLP exhibits the N-and C-terminal groups of the coat proteins on capsid surface facilitating its purification and antigen presentation on capsid surface. Hence, AP205 is an ideal building block for advanced structured biomaterials. Furthermore, the AP205 VLP is similar in size to Qbeta, has a smoother surface, and features a more uniform charge distribution. These distinctions offer valuable insights into how those properties, especially regarding surface roughness, distributions of surface charge, and hydrophobic groups, affect the protein nanocage self-assembly to suprastructures. Small-angle X-ray scattering (SAXS), dynamic light scattering (DLS), and zeta potential (ZP) are applied to characterize the AP205 VLP suprastructure formation in the presence and absence of pMETAC, depending on ionic strength and pH in suspension. These findings advance the understanding of VLP-based materials for biomedical applications.
