Biological cells self-organize into living materials that uniquely blend structure with functionality and responsiveness to the environment. The integration of similar life-like features in man-made materials remains challenging, yet desir-able to manufacture active, adaptive and autonomous systems. Here we show the self-organization of programmable random lasers from the reversible out-of-equilibrium self-assembly of colloids. Random lasing originates from the optical amplification of light…

Low-threshold nanolasers based on miniaturized bound states in the continuum

(Dated: The pursuit of compact lasers with low-thresholds has imposed strict requirements on tight light confinements with minimized radiation losses. Bound states in the continuum (BICs) have been



Light-controlled assembly of active colloidal molecules.

This work exemplifies the possibility to control the dynamics of active self-assembly via light-controllable nonreciprocal interactions by creating active molecules featuring a complex array of behaviors, becoming migrators, spinners, and rotators.

Spatially and temporally reconfigurable assembly of colloidal crystals.

A photo-induced assembly method that yields regions either filled with colloidal crystals or completely devoid of colloids, which represents a new kind of template-free, reconfigurable three-dimensional photolithography.

Dissipative self-organization in optical space

Self-organization far from thermal equilibrium in a thermo-optical feedback process occurring in a random array of Fabry–Pérot resonators is shown, adding new capability to dynamic self-assembly in creating materials with fine-tuned adaptive responses.

Self-assembled nematic colloidal motors powered by light

A self-assembled colloidal motor with a repetitive light-driven rotation of transparent micro-particles immersed in a liquid crystal and powered by a continuous exposure to unstructured ~1 nW light is described.

Non‐Equilibrium Assembly of Light‐Activated Colloidal Mixtures

The crystallization of passive silica colloids into well-controlled 2D assemblies is shown, which is directed by a small number of self-propelled active colloids, which offers the possibility of obtaining structures and assemblies that cannot be found in equilibrium systems.

Self-assembled colloidal structures for photonics

Colloidal self-assembly has been investigated as a promising and practical approach for the fabrication of photonic nanostructures, including colloidal crystals, composite and inverse opals, and

Universality of dissipative self-assembly from quantum dots to human cells

An important goal of self-assembly research is to develop a general methodology applicable to almost any material, from the smallest to the largest scales, whereby qualitatively identical results are

Targeted assembly and synchronization of self-spinning microgears

The targeted formation of self-powered microgears from active particles and their autonomous synchronization into dynamical superstructures is shown, laying the groundwork for the autonomous construction of dynamical architectures and functional micro-machinery.

Dissipative self-assembly of vesicular nanoreactors.

It is shown that the lifetime of the vesicles can be regulated by controlling the hydrolysis rate of ATP, and a new strategy for the dissipative self-assembly of functional supramolecular structures with high structural complexity is shown.

Reconfiguring active particles by electrostatic imbalance.

A general strategy to reconfigure active particles into various collective states by introducing imbalanced interactions is presented, and this strategy of asymmetry-driven active self-organization should generalize rationally to other active 2D and three-dimensional materials.
