Query: Single-Chain Nanoparticles under Homogeneous Shear Flow   Single-chain nanoparticles (SCNPs) are a new class of macromolecular objects,
synthesized through purely intramolecular cross-linking of single polymer
chains. We use a multi-scale hydrodynamics simulation approach to study, for
the first time, SCNPs under shear flow. We investigate the case of irreversible
SCNPs (permanent cross-links) in dilute solution. SCNPs emerge as a novel class
of macromolecular objects with response to shear distinct from other systems
such as linear chains, star polymers, rings or dendrimers. This is evidenced by
the observed set of scaling exponents for the shear rate dependence of the SCNP
static and dynamic properties. Surprisingly these exponents are, at most,
marginally dependent on the specific topology of the SCNP (globular or sparse),
suggesting that they are inherently related to the network-like character of
the molecular architecture and not to its specific connectivity. At high
Weissenberg numbers the dynamics of the sparse SCNPs is dominated by tumbling
motion, whereas tank-treading predominates for the most globular SCNPs.
