Ligand selection is thus critical in determining NP surface properties and corresponding interactions at the nano-bio interface, which are relevant to numerous applications including drug delivery and biosensing. However, chemically specific structure-property relationships for rationally selecting ligands to achieve desired biointeractions are largely lacking. In this Focus Article, we review the challenges associated with relating ligand chemical properties to monolayer-protected NP surface properties due to the interplay of ligand-ligand, ligand-solvent, and ligand-biomolecule interactions that are difficult to anticipate. In particular, we highlight unexpected spatially varying properties that emerge even for uniformly functionalized NPs due to the fluctuations of ligands at the nanoscale. We further review the capability of physics-based molecular simulations to reveal these unexpected behaviors, providing powerful computational methods to predict NP properties.

However, it remains a great challenge to prepare such structures using a convenient method. Herein, an innovative method inspired by the bud-growth of plants (bud-notching and bud-picking) was proposed to prepare multi-branched hydrogel tubes based on sodium alginate/copper ions (Na-Alg/Cu<sup>2+</sup>). The bud-notching technique refers to the selective decrosslinking of Na-Alg/Cu<sup>2+</sup> gels by controlled ethanolamine treatment, resulting in an \"opening\" in the tube wall. By adjusting the location and number of bud-notching on the primary tube and combining the apical growth technique, branched hydrogel tubes with diverse dimensions (two and three-dimensional) and structures (\"zigzag\"-shaped and \"helical\"-shaped) could be prepared on demand, without the need for templates and expensive equipment. Furthermore, biomimetic multi-segment hydrogel tubes were fabricated as simplified models to investigate the stability at the connection sites. The results demonstrated that the secondary hydrogel tubes prepared through multi-step growth retained approximately 70% of the elongation at break and 90% of the fracture force compared to the directly formed monolithic hydrogel tubes. Furthermore, the perfusion experiments showed that connections between branches were stable, which made the developed multi-branched hydrogel tubes have promising applications in some <i>in vitro</i> models and fluidic transport application areas.

In this work, we propose a \"critical network equilibrium\" mechanism enabled by molecular weight-optimized dextran (DEX).

Moreover, the D7-mediated interface preferentially directs Zn<sup>2+</sup> deposition onto the Zn(002) plane, while inhibiting disordered growth on the Zn(101) plane. Experimental results indicate that the Zn//Zn cell modified with D7 exhibits an ultra-stable lifespan of up to 4800 h at 1 mA cm<sup>-2</sup>/1 mA h cm<sup>-2</sup>, while the Zn//MnO<sub>2</sub> full-cell retains 83% of its capacity after 3000 cycles.

This enables autonomous switching between non-functional and functional states, however, their behavior remains reactive, limiting their ability to perform complex adaptive tasks. Here, we present a reprogrammable LCE actuator capable of autonomously sorting objects based on their green-light transmission properties. Using perylene diimide-doped LCEs and controlled green-light illumination, the actuator senses the optical properties of the object, establishing an actuation plan through spatial radical generation. Subsequent far-red irradiation triggers different actuation modes, enabling selective object sorting. This pattern-encoded actuation allows objects with different optical characteristics to trigger specific mechanical responses under identical illumination conditions. This single-material system, which is optically resettable, integrates sensory feedback, deliberative decision-making, and adaptive mechanical responses.
