While natural helical morphologies offer remarkable multifunctionality, replicating their complexity in artificial systems remains a significant challenge. In a recent issue of Cell Reports Physical Science, Xiao and colleagues reported 3D-printed thermoresponsive LCE bilayers that realize tailored helical morphologies. By establishing energy-based phase diagrams, they demonstrated precise programming of gradient helices with potential applications in biomimetic replication, adaptive grippers, and self-steering rolling robots.

Metal-organic frameworks (MOFs) as a promising porous material for sorption-based applications have received much attention. Despite their great potential showcased over the past decade, their utilization is mainly limited to the laboratory level, primarily due to the shortcomings of their powdery form. Hence, strategies for shaping MOFs for mechanical stability and enhanced heat and mass transfer are prioritized. Although mechanical compression with or without binders is commonly used, this approach reduces the sorption capacity of the MOF and prevents it from reaching ideal sorption kinetics. By contrast, the fabrication of MOF coatings and membranes and the formation of MOF monoliths have been explored to achieve structural integrity and superior performance. This review expands this scope by summarizing the state-of-the-art shaping methods of MOFs with diverse structures, analyzing the mechanisms for performance enhancement and demonstrating their application potential. Moreover, the challenges of scaling up MOF-based systems and the future outlook are presented to further the development of next-generation advanced MOF materials.

Non-centrosymmetric oxides have gained attention for their wide-ranging applications. Preparing two-dimensional (2D) non-centrosymmetric oxides is a prerequisite for on-chip integration but is challenging due to multi-element components and strong interlayer interactions. Here, we develop a thermal-expansion-difference-driven high-pressure strategy for synthesizing 2D non-centrosymmetric MnTeMoO6 with extraordinary nonlinear optical properties. By utilizing the large thermal expansion mismatch between copper and graphite, the growth space is squeezed to a tiny slit with a high pressure of up to 20 MPa. This process reduces reaction activation energy and the precursor mean free path, yielding ultrathin flakes (down to two-unit cells) with uniform stoichiometry. The layer-parity-independent non-centrosymmetric structure of 2D MnTeMoO6 results in one of the strongest second-harmonic generations among 2D oxides, with its second-order nonlinear susceptibility approaching the theoretical limit. This work not only offers a novel method to grow multi-element 2D oxides but also provides material platforms for miniaturized nonlinear optics.

Microactuators driven by shape transformation achieve targeted functionality through tailored geometric designs. However, reliance on simplistic configurations restricts the understanding of deformation behavior and the versatility of adaptive systems. Here, we demonstrate geometrically guided actuation of hydrogel pores by controlling folding dynamics. Unlike non-faceted circular pores that exhibit randomized folding, hinges in faceted pores direct folding along predefined vertices, enabling control over the degree of constriction and restoration of the pores. By systematically designing key geometrical factors, such as the shape, dimensions, and spatial proximity to neighboring units, we effectively regulate shape transformation, aided by classical plate theory and finite element analysis. The resulting geometry-dependent adaptable topologies enable controlled entrapment and sequential release of microparticles, as well as information encryption through fine-tuned and localized pore actuation. This approach to adaptive micropore actuation controlled by facet-driven folding opens new possibilities for developing microactuators, particularly in applications requiring precise microobject manipulation.

Organic-inorganic metal halides (OIMHs) exhibit remarkable thermodynamic transitions between crystalline and amorphous states, yet their potential application in optical fibers has not been explored. In this study, we present a melt-filling strategy leveraging the low-temperature (230°C) fluidity of (HTPP)2MnBr4 and (HTPP)2SbBr5 (HTPP = hexyltriphenylphosphonium) glasses to fabricate optical fibers with controllable diameters and lengths. These OIMH fibers processed at 230°C feature a core-cladding structure with minimal defects, achieving remarkably low transmission losses of 0.41 dB/cm for Mn-based fibers and 0.16 dB/cm for Sb-based fibers, along with exceptional mechanical flexibility (bending radius ≤0.8 mm). These optical fibers enable information encryption systems and reliable light transmission under bending, demonstrating their potential applications in optical encryption and integrated photonics. This work establishes OIMHs as promising candidates for next-generation optical waveguides.

Current 4D materials typically rely on external stimuli such as heat or light to accomplish changes in shape, limiting the biocompatibility of these materials. Here, a composite bioink consisting of oxidized and methacrylated alginate (OMA), methacrylated gelatin (GelMA), and gelatin microspheres is developed to accomplish freestanding 4D bioprinting of cell-laden structures driven by an internal stimulus: cell contractile forces (CCFs). 4D changes in shape are directed by forming bilayer constructs consisting of one cell-free and one cell-laden layer. Human mesenchymal stem cells (hMSCs) are encapsulated to demonstrate the ability to simultaneously induce changes in shape and chondrogenic/osteogenic differentiation. Finally, the capability of patterning each layer of the printed constructs to obtain complex geometric changes—including bending around two separate, non-parallel axes—is exhibited. Bioprinting of such 4D constructs mediated by CCFs empowers the formation of more complex constructs, contributing to a greater degree of in vitro biomimicry of biological 4D phenomena.

Urine, an easily accessible body fluid, contains rich metabolic compounds reflecting the human health condition. Though urine analysis can be carried out by many conventional analytical methods, direct, rapid, and simultaneous identification of a variety of urinary metabolites by a handheld device remains challenging. Recent developments in nanopore small molecule sensing may suggest direct urine analysis performed by an engineered nanopore. Here, a hetero-octameric Mycobacterium smegmatis porin A (MspA) nanopore immobilized with a single nickel ion is confirmed to be suitable for the simultaneous identification of six urinary metabolites: creatinine, taurine, histidine, 1-methylhistidine, 3-methylhistidine, and hypoxanthine. With the assistance of machine learning, an overall accuracy of 98.5% was reported. This urine sensing capacity was further applied in real-time urinary metabolite monitoring after diet and physical exercise. These proofs of concept suggest a variety of nanopore-based body fluid analyses for early diagnosis, health management, pharmacokinetic monitoring, and doping tests.

Ceramics from chemically distinct preceramic polymers offer unique shaping and microstructural control but face challenges such as shrinkage, uncontrolled porosity, and pyrolysis-sensitive stoichiometry. The high-temperature potential of compositionally complex ceramics is further constrained by precursor scarcity and the low-throughput nature of pyrolysis. Here, we introduce short-chain preceramic precursors crosslinked with group IV–VI transition metals (Zr, Cr, V, Mo, Hf, W, Nb, etc.), which are compatible with additive manufacturing. We explored extrusion and ultrafast pyrolysis with multi-metal precursors to enable enhanced compositional complexity, lower processing temperatures, and rapid screening of oxidation-resistant ceramics. Through ultrafast electrical pyrolysis, these crosslinked precursors convert into dense, multi-phase ceramics in under a minute. The resulting materials exhibit homogeneous composition and oxidation resistance up to 1,873 K, offering a scalable route to protective coatings and bulk ceramics for extreme environments.

Intraoperative and spatiotemporal monitoring of neuroinflammatory indices during brain-computer interface (BCI) implantation is essential for ensuring safety and efficacy of the procedure. Current biomolecular detection approaches are unable to obtain spatiotemporally resolved inflammatory profiling, which is important for guiding the placement of microelectrodes intraoperatively. This study presents an intraoperative spatiotemporal acute inflammation detector (ISAID) that harnesses droplet-based sampling and multiplexed titanium oxynitride (TiNO) plasmonic biosensing to assess local inflammation during the insertion of intracortical microelectrodes. Through freestanding sampling droplets and fine-tuned TiNO-based biosensors, the ISAID achieved precise, sensitive, and integrated sampling to biosensing for cytokine detection with a spatial resolution down to 610 μm and a fast equivalent bioassay time of 1.25 min. The proposed system also allows multiple ISAID biosensing modes, enabling both spatial inflammation mapping and multi-cytokine analysis. Quantitative analyses of inflammatory cytokines with in vivo mouse models demonstrate the accuracy and practical advantages of the system.
