Summary

Giuseppe Battaglia presents a seminar on mimicking biological emergent properties for biomaterial design. He introduces his research group’s focus on advanced therapies using block copolymers that self-assemble into nanostructures. The talk emphasizes the importance of emergence in living systems, where complexity arises from interactions among components. Battaglia discusses multivalency as a key principle: by attaching multiple ligands to a polymer scaffold, the binding becomes super-selective, dependent on receptor density rather than affinity alone. This allows targeting of specific cell phenotypes, such as brain endothelial cells, while avoiding off-target effects. He also explores how steric hindrance can modulate binding, leading to non-monotonic behaviors. The seminar covers the use of liquid-phase electron microscopy to characterize soft materials, and simulations showing collective effects in membrane deformation and tubulation, which are relevant for drug delivery across the blood-brain barrier. The talk concludes with implications for designing materials that exploit these emergent properties for therapeutic applications.
