The functionalization of nanoparticles (NPs) with DNA has proven to be an effective strategy for self-assembly of NPs into superlattices with a broad range of lattice symmetries. By combining this strategy with the DNA origami approach, the possible

The ability to fabricate materials and devices by-design at small scales, largely based in advances in lithographic and additive manufacturing methods, has led to the tremendous technological progress of the last decades. However, the growing need to

We use molecular dynamics simulations to study how the chain length affects the structure and segmental dynamics of polymer–nanoparticle (NP) composites at semidilute NP concentrations. For NPs hav...

Advances in nanoscale self-assembly have enabled the formation of complex nanoscale architectures. However, the development of self-assembly strategies toward bottom-up nanofabrication is impeded by challenges in revealing these structures volumetric

The modification of interfacial polymer behavior is one of the primary sources of property modifications of polymer–nanoparticle (NP) composites (PNC). For strongly favorable polymer–nanoparticle i...

When polymer–nanoparticle (NP) attractions are sufficiently strong, a bound polymer layer with a distinct dynamic signature spontaneously forms at the NP interface. A similar phenomenon occurs near a fixed attractive substrate for thin polymer film

We quantify the properties of the interfacial layers around bare nanoparticles (NPs) with variable NP diameter in model polymer-NP composites and near the solid substrate and free interfaces of supported thin polymer films using molecular simulations

Engineering the assembly of nanoscale objects into complex and prescribed structures requires control over their binding properties. Such control might benefit from a well-defined bond directionality, the ability to designate their engagements throug

Using molecular simulations on model polymer nanocomposites at fixed filler loading, we show that interfacial polymer dynamics are affected less with decreasing nanoparticle (NP) size. However, the glass transition temperature ${T}_{g}$ changes subst

Controlled colloid bonding using DNA Colloidal particles can act as analogs of atoms for studying crystallization and packing behavior, but they don't naturally bond together the way atoms do. Short strands of DNA are one versatile way to link togeth
