text: 'Physiological void spaces exist at every scale of the human body, from organs
to molecules, facilitating transport, signal propagation, and localized biochemical
activity. Constriction of these spaces (e.g., arterial occlusion, fibrosis) highlights
their importance, making their mimicry essential in tissue engineering (TE). This
review examines four key strategies for introducing porosity into hydrogels across
multiple length scales: templating, microgels, phase separation, and 3D printing.
The first three methods enable the engineering of physiological environments at
the nano‐ to micro‐scale, mimicking tissue‐ and extracellular matrix (ECM)‐level
spaces. Templating involves embedding and removal of gas, liquid, or solid phases,
leaving behind pores. Microgel annealing generates inherent interstitial voids.
Liquid–liquid phase separation (LLPS) creates biphasic networks reminiscent of
native ECM. The fourth approach, extrusion‐ and light‐based 3D printing techniques,
enables the fabrication of larger‐scale spaces, such as luminal structures (e.g.,
vasculature, airways, and ducts). Combining these methods enables the creation
of hierarchical architectures from the nano‐ to centimeter scale. The review also
highlights Filamented Light (FLight) technology, which creates internal microstructural
voids relevant to anisotropic tissues. This review offers insights into current
methods and their convergence for generating biomimetic void spaces to meet the
physiological demands of cells, tissues, and organs.'

text: Elastic MicroPhase separation (EMPS) provides a simple route to create soft
materials with homogeneous microstructures by leveraging the supersaturation of
crosslinked polymer networks with liquids. At low supersaturation, network elasticity
stabilizes a uniform mixture, but beyond a critical threshold, metastable microphase-separated
domains emerge. While previous theories have focused on describing qualitative
features about the size and morphology of these domains, they do not make quantitative
predictions about EMPS phase diagrams. In this work, we extend Flory–Huggins theory
to quantitatively capture EMPS phase diagrams by incorporating strain-stiffening
effects. This model requires no fitting parameters and relies solely on independently
measured solubility parameters and large-deformation mechanical responses. Our
results confirm that strain-stiffening enables metastable microphase separation
within the swelling equilibrium state and reveal why the microstructures can range
from discrete droplets to bicontinuous networks. This works highlights the critical
role of nonlinear elasticity in controlling phase-separated morphologies in polymer
gels.

text: Unlike biological active matter that constantly adapt to their environment,
the motors of synthetic active particles are typically agnostic to their surroundings
and merely operate at constant force. Here, we design colloidal active rods capable
of modulating their inner activity in response to crowding, thereby enforcing
a primitive form of quorum sensing interactions. Through experiments, simulations,
and theory we elucidate the impact of these interactions on the phase behavior
of isotropic active matter. We demonstrate that, when conditioned to density,
motility regulation can either lead to an absorbing phase transition, where all
particles freeze their dynamics, or to atypical phase separation, where flat interfaces
supporting a net pressure drop are in mechanical equilibrium. Fully active and
fully arrested particles can then form heterogeneous patterns ruled by the competition
between quorum sensing and mechanical interactions. Beyond the specifics of motile
colloids, we expect our findings to apply broadly to adaptive active matter assembled
from living or synthetic units.

text: Highly interconnected percolated networks are interesting structures for materials
with enhanced transport and mechanical properties. While percolated networks of
anisotropic particles have been explored at the nanoscale, achieving highly interconnected
structures at the microscale remains challenging. In this work, we explore the
controlled assembly of rod-like polymer colloids under external fields leading
to reversible quasi-2D networks. By varying voltage and frequency, we modulate
the pore size and thickness of the network. We find that field-driven attractive
interactions enable percolation at lower area fractions than predicted for non-interacting
rods. Monte Carlo simulations incorporating dipolar interactions and electrostatic
boundary conditions confirm the field-induced transition from isotropic to aligned
rod configurations, supporting the emergence of percolated networks. This work
presents a simple and robust approach for assembling reconfigurable colloidal
networks with controlled connectivity, offering new strategies for designing adaptive
soft materials.

text: The curvature of elongated microscopic building blocks plays a crucial role
on their self-assembly into orientationally ordered phases. While rod-like molecules
form a handful of liquid crystal (LC) phases, curved or banana-shaped molecules
show more than fifty phases, with fascinating physical properties, such as chirality
or polarity. Despite the fundamental and technological importance of these so-called
‘banana-shaped liquid crystals’, little is known about their microscopic details
at the single-molecule level. Curved colloidal liquid crystals—liquid crystals
formed by curved colloidal rods—are excellent model systems to optically resolve
the structure and dynamics of curved building blocks within these condensed phases.
Recent advances in the synthesis of curved rod-like particles have unlocked the
potential for studying—at the single-particle level—the intimate relationship
between shape and phase symmetry, and even confirmed the stability of elusive
LC phases. Further developments in this nascent field promise exciting findings,
such as the first observation of the colloidal twist-bend nematic phase or the
fabrication of functional materials with curvature-dependent properties. In this
Report on Progress, we will highlight recent advances in the synthesis and assembly
of curved colloidal liquid crystals and discuss the upcoming challenges and opportunities
of this field.

text: 'Bicontinuous microstructures are essential to the function of diverse natural
and synthetic systems. Their synthesis has been based on two approaches: arrested
phase separation or self-assembly of block copolymers. The former is attractive
for its chemical simplicity and the latter, for its thermodynamic robustness.
Here we introduce elastic microphase separation (EMPS) as an alternative approach
to make bicontinuous microstructures. Conceptually, EMPS balances the molecular-scale
forces that drive demixing with large-scale elasticity to encode a thermodynamic
length scale. This process features a continuous phase transition, reversible
without hysteresis. Practically, EMPS is triggered by simply supersaturating an
elastomeric matrix with a liquid, resulting in uniform bicontinuous materials
with a well-defined microscopic length scale tuned by the matrix stiffness. The
versatility of EMPS is further demonstrated by fabricating bicontinuous materials
with superior mechanical properties and controlled anisotropy and microstructural
gradients. Overall, EMPS presents a robust alternative for the bulk fabrication
of homogeneous bicontinuous materials.'

text: "Anisotropic colloidal particles exhibit complex dynamics which play a crucial
role in their functionality,\r\ntransport, and phase behavior. In this Letter,
we investigate the two-dimensional diffusion of smoothly curved\r\ncolloidal rods—also
known as colloidal bananas—as a function of their opening angle α. We measure
the\r\ntranslational and rotational diffusion coefficients of the particles with
opening angles ranging from 0◦ (straight\r\nrods) to nearly 360◦(closed rings).
In particular, we find that the anisotropic diffusion of the particles varies\r\nnonmonotonically
with their opening angle and that the axis of fastest diffusion switches from
the long to the\r\nshort axis of the particles when α> 180◦. We also find that
the rotational diffusion coefficient of nearly closed\r\nrings is approximately
an order of magnitude higher than that of straight rods of the same length. Finally,
we\r\nshow that the experimental results are consistent with slender body theory,
indicating that the dynamical behavior\r\nof the particles arises primarily from
their local drag anisotropy. These results highlight the impact of curvature\r\non
the Brownian motion of elongated colloidal particles, which must be taken into
account when seeking to\r\nunderstand the behavior of curved colloidal particles."

text: Phase separation is a ubiquitous process and finds applications in a variety
of biological, organic, and inorganic systems. Nature has evolved the ability
to control phase separation to both regulate cellular processes and make composite
materials with outstanding mechanical and optical properties. Striking examples
of the latter are the vibrant blue and green feathers of many bird species, which
are thought to result from an exquisite control of the size and spatial correlations
of their phase-separated microstructures. By contrast, it is much harder for material
scientists to arrest and control phase separation in synthetic materials with
such a high level of precision at these length scales. In this Perspective, we
briefly review some established methods to control liquid–liquid phase separation
processes and then highlight the emergence of a promising arrest method based
on phase separation in an elastic polymer network. Finally, we discuss upcoming
challenges and opportunities for fabricating microstructured materials via mechanically
controlled phase separation.

text: Hierarchically self-assembled materials—structures with order at multiple
length scales—can be found everywhere. Examples range from collagen structures
in human bones to engineered photonic materials. These structures usually assemble
from monodisperse microscopic building blocks that interact via complex directional
interactions. In this work, we show that hierarchical materials can, in fact,
also be assembled from polydisperse building blocks and by entropic interactions
alone. Our simple yet powerful assembly mechanism opens up avenues toward rationally
exploiting the often undesired polydispersity of colloidal building blocks for
programming entropy-driven self-assembly of hierarchical materials.

text: Surface roughness plays an important role in determining the mechanical properties,
wettability, and self-assembly in colloidal systems. In this work, we develop
a simple and fast method to produce rough colloidal SU-8 rods, bananas, and spheres,
via the nanoprecipitation of SU-8 in water. During this process, SU-8 nanospheres
are absorbed onto the surface of the colloidal SU-8 particles and then cross-linked
using UV-light. The size of the spherical asperities and the asperity density
are controlled by the concentration of SU-8 used during the nanoprecipitation
reaction. Fluorescent labeling of the rough SU-8 colloidal particles allows for
their confocal imaging, which demonstrates their stability at high packing fractions.
With these newly developed rough particles, we provide a colloidal model system
that allows for studies addressing the impact of surface roughness on materials
composed of anisotropic particles.

text: Understanding the impact of curvature on the self-assembly of elongated microscopic
building blocks, such as molecules and proteins, is key to engineering functional
materials with predesigned structure. We develop model “banana-shaped” colloidal
particles with tunable dimensions and curvature, whose structure and dynamics
are accessible at the particle level. By heating initially straight rods made
of SU-8 photoresist, we induce a controllable shape deformation that causes the
rods to buckle into banana-shaped particles. We elucidate the phase behavior of
differently curved colloidal bananas using confocal microscopy. Although highly
curved bananas only form isotropic phases, less curved bananas exhibit very rich
phase behavior, including biaxial nematic phases, polar and antipolar smectic-like
phases, and even the long-predicted, elusive splay-bend nematic phase.

text: The bulk synthesis of fluorescent colloidal SU‐8 polymer rods with tunable
dimensions is described. The colloidal SU‐8 rods are prepared by shearing an emulsion
of SU‐8 polymer droplets and then exposing the resulting non‐Brownian rods to
ultrasonic waves, which breaks them into colloidal rods with typical lengths of
3.5–10 µm and diameters of 0.4–1 µm. The rods are stable in both aqueous and apolar
solvents, and by varying the composition of apolar solvent mixtures both the difference
in refractive index and mass density between particles and solvent can be independently
controlled. Consequently, these colloidal SU‐8 rods can be used in both 3D confocal
microscopy and optical trapping experiments while carefully tuning the effect
of gravity. This is demonstrated by using confocal microscopy to image the liquid
crystalline phases and the isotropic–nematic interface formed by the colloidal
SU‐8 rods and by optically trapping single rods in water. Finally, the simultaneous
confocal imaging and optical manipulation of multiple SU‐8 rods in the isotropic
phase is shown.

text: We disclose a method for the synthesis of chiral colloids from spontaneously
formed hollow sugar-surfactant microtubes with internally confined mobile colloidal
spheres. Key feature of our approach is the grafting of colloid surfaces with
photoresponsive coumarin moieties, which allow for UV-induced, covalent clicking
of colloids into permanent chains, with morphologies set by the colloid-to-tube
diameter ratio. Subsequent dissolution of tube confinement yields aqueous suspensions
that comprise bulk quantities of a variety of linear chains, including single
helical chains of polystyrene colloids. These colloidal equivalents of chiral
(DNA) molecules are intended for microscopic study of chiral dynamics on a single-particle
level.
