Article Abstract
Covalent co-assembly holds great promise for the fabrication of hydrogels with controllable nanostructure, versatile chemical composition, and enhanced mechanical properties given its relative simplicity, high efficiency, and bond stability. This report describes our approach to designing functional multicomponent hydrogels based on photo-induced chemical interactions between an acrylamide-functionalized resilin-like polypeptide (RLP) and a peptide amphiphile (PA). Circular dichroism (CD) spectroscopy, electron microscopy, and amplitude sweep rheology were used to demonstrate that the co-assembled hydrogel systems acquired distinct structural conformations, tunable nanostructures, and enhanced elasticity in a PA concentration-dependent manner. We envisage the use of these materials in numerous biomedical applications such as controlled drug release systems, microfluidic devices, and scaffolds for tissue engineering.

Colloidal particles can co-assemble into multicomponent ordered superstructures, with their properties determined by the individual building blocks. Here, we demonstrate that covalent organic framework (COF) particles can co-assemble into binary ordered superstructures through solvent evaporation within confined spaces. By adjusting the particle size ratio, we prepare 2D COF-COF binary ordered superstructures with different stoichiometries (LS and LS), underscoring entropic control over the assembly process.

Stimuli-responsive surfactants have garnered significant attention as promising candidates for diverse applications in efficient oil recovery, programmable all-liquid devices, and microreactors owing to their dynamic interfacial self-assembly behavior under specific triggers. However, contemporary applications of stimuli-responsive surfactants remain constrained within monofunctional paradigms, significantly impeding their integration into advanced multifunctional manufacturing. Here, an interesting pH-responsive gemini surfactant is reported that can dynamically switch between gemini (GTL, pH ≥ 8.

Molecular self-assembly enables the formation of intricate networks through non-covalent interactions, serving as a key strategy for constructing structures ranging from molecules to macroscopic forms. While zero-dimensional and one-dimensional nanostructures have been widely achieved, two-dimensional nanostrip structures present unique advantages in biomedical and other applications due to their high surface area and potential for functionalization. However, their efficient design and precise regulation remain challenging.
