TLDR
The transient self-assembly of synthetic molecules into active materials, driven by the consumption of a chemical fuel is reported.Abstract:
Fuel-driven self-assembly of actin filaments and microtubules is a key component of cellular organization. Continuous energy supply maintains these transient biomolecular assemblies far from thermodynamic equilibrium, unlike typical synthetic systems that spontaneously assemble at thermodynamic equilibrium. Here, we report the transient self-assembly of synthetic molecules into active materials, driven by the consumption of a chemical fuel. In these materials, reaction rates and fuel levels, instead of equilibrium composition, determine properties such as lifetime, stiffness, and self-regeneration capability. Fibers exhibit strongly nonlinear behavior including stochastic collapse and simultaneous growth and shrinkage, reminiscent of microtubule dynamics.read more

Emergent behavior in active colloids
TL;DR: Active colloids are microscopic particles which self-propel through viscous fluids by converting energy extracted from their environment into directed motion as discussed by the authors, where artificial microswimmers move forward by generating near-surface flow fields via self-phoresis or the self-induced Marangoni effect.

Supramolecular materials based on AIE luminogens (AIEgens): construction and applications
TL;DR: The emergence of aggregation-induced emission luminogens (AIEgens) has significantly stimulated the development of luminescent supramolecular materials because their strong emissions in the aggregated state have resolved the notorious obstacle of the aggregation-caused quenching (ACQ) effect.

Self-organization of microtubules and motors
TL;DR: It is shown that dynamic asters can also be obtained from a homogeneous solution of tubulin and motors, and it is demonstrated that the same final structure can be reached through different assembly ‘pathways’.
