Abstract
Inspired by natural hierarchical self-assembly of proteins and peptides, amino acids, as the basic building units, have been shown to self-assemble to form highly ordered structures through supramolecular interactions. The fabrication of functional biomaterials comprised of extremely simple biomolecules has gained increasing interest due to the advantages of biocompatibility, easy functionalization, and structural modularity. In particular, amino acid based assemblies have shown attractive physical characteristics for various bionanotechnology applications. Herein, we propose a review paper to summarize the design strategies as well as research advances of amino acid based supramolecular assemblies as smart functional materials. We first briefly introduce bioinspired reductionist design strategies and assembly mechanism for amino acid based molecular assembly materials through noncovalent interactions in condensed states, including self-assembly, metal ion mediated coordination assembly, and coassembly. In the following part, we provide an overview of the properties and functions of amino acid based materials toward applications in nanotechnology and biomedicine. Finally, we give an overview of the remaining challenges and future perspectives on the fabrication of amino acid based supramolecular biomaterials with desired properties. We believe that this review will promote the prosperous development of innovative bioinspired functional materials formed by minimalistic building blocks.

Abstract
Hydrogels with rapid gelation ability and robust mechanical properties are highly desirable for nascent applications in biomedical, wearable electronic, industrial and agricultural fields. However, current rapid-gelation hydrogels are compromised by poor mechanical properties, complex design of precursor molecular structures and limited precursor species. Herein, we propose a facile and universal strategy to achieve rapid gelation, strengthening and toughening of free-radical polymerized hydrogels by introducing cheap and accessible amino acids. Amino acids not only activate persulfate to quickly produce free radicals and thus induce fast free radical polymerization, but also can form strong hydrogen bonds with the network chains to strengthen and toughen the hydrogels. For example, with the presence of L-serine, the acrylamide (AM) monomer shows rapid gelation within tens of seconds, and moreover the resulting hydrogel reaches a tensile strength of 0.45 MPa and a breaking strain of 2060%. More importantly, owing to the extremely dynamic feature of the hydrogen bonds between L-serine molecules and network chains, the hydrogel possesses the advantages of low hysteresis, rapid self-recovery capability and outstanding fatigue resistance. Furthermore, this strategy is general to a wide range of amino acids and monomers. We also demonstrate that this rapid, controllable and universal strategy for the fabrication of mechanically robust hydrogels holds tremendous potential for diverse practical applications, such as flexible electronic sensors and ultraviolet (UV)-blocking artificial skins.

Abstract
Ester is one of the most prevalent functional groups in natural and man-made products. Natural esterases hydrolyze nonactivated alkyl esters readily but artificial esterases generally use highly activated p-nitrophenyl esters as substrates. We report synthetic esterases constructed through molecular imprinting in cross-linked micelles. The water-soluble nanoparticle catalysts contain a thiouronium cation to mimic the oxyanion hole and a nearby base to assist the hydrolysis. Whereas this catalytic motif readily affords large rate acceleration for the hydrolysis of p-nitrophenyl hexanoate, nonactivated cyclopentyl hexanoate demands catalytic groups that can generate a strong nucleophile (hydroxide) in the active site. The hydroxide is stabilized by the protonated base when the external solution is at pH 7, enabling the hydrolysis of activated and nonactivated esters under neutral conditions.

Abstract
Carbon dots (CDs) are widely utilized in sensing, energy storage, and catalysis due to their excellent optical, electrical and semiconducting properties. However, attempts to optimize their optoelectronic performance through high-order manipulation have met with little success to date. In this study, through efficient packing of individual CDs in two-dimensions, the synthesis of flexible CDs ribbons is demonstrated technically. Electron microscopies and molecular dynamics simulations, show the assembly of CDs into ribbons results from the tripartite balance of π-π attractions, hydrogen bonding, and halogen bonding forces provided by the superficial ligands. The obtained ribbons are flexible and show excellent stability against UV irradiation and heating. CDs ribbons offer outstanding performance as active layer material in transparent flexible memristors, with the developed devices providing excellent data storage, retention capabilities, and fast optoelectronic responses. A memristor device with a thickness of 8 µm shows good data retention capability even after 104 cycles of bending. Furthermore, the device functions effectively as a neuromorphic computing system with integrated storage and computation capabilities, with the response speed of the device being less than 5.5 ns. These properties create an optoelectronic memristor with rapid Chinese character learning capability. This work lays the foundation for wearable artificial intelligence.

Abstract
Originally regarded as a disease symptom, amyloids have shown a rich diversity of functions, including biologically beneficial ones. As such, the traditional view of polypeptide aggregation into amyloid-like structures being 'misfolding' should rather be viewed as 'alternative folding.' Various amyloid folds have been recently used to create highly efficient catalysts with specific catalytic efficiencies rivaling those of enzymes. Here we summarize recent developments and applications of catalytic amyloids, derived from both de novo and bioinspired designs, and discuss how progress in the last 2 years reflects on the field as a whole.

Abstract
The realization of the ability of metabolites to form self-assembled amyloid-like nanostructures was a surprising phenomenon. This discovery paved the way towards understanding the pathophysiology of the inborn error of metabolism disorders from a new perspective, relating them to amyloid-associated diseases that are characterized by the aggregation of proteins and polypeptides. Hence, a 'generic amyloid hypothesis' can be proposed. This theory implies that the formation of amyloid-like structures is a general phenomenon not limited to proteins and reflects a common etiology for both age-related amyloid-associated diseases and inborn error of metabolism disorders. Here, we present a comprehensive survey of the recent research related to metabolite amyloids including their structure formation through self-association, propagation, interactions, transmission, and their role in metabolic disorders and neurodegenerative diseases and their applications for the fabrication of novel materials which implicate metabolite assemblies as a surprising extension to the amyloid scheme.

Abstract
The self-assembly of short peptides gives rise to versatile nanoassemblies capable of promoting efficient catalysis. We have semi-rationally designed a series of seven-residue peptides that form hemin-binding catalytic amyloids to facilitate enantioselective cyclopropanation with efficiencies that rival those of engineered hemin proteins. These results demonstrate that: 1) Catalytic amyloids can bind complex metallocofactors to promote practically important multisubstrate transformations. 2) Even essentially flat surfaces of amyloid assemblies can impart a substantial degree of enantioselectivity without the need for extensive optimization. 3) The ease of peptide preparation allows for straightforward incorporation of unnatural amino acids and the preparation of peptides made from d-amino acids with complete reversal of enantioselectivity.
