Proteinaceous Fibers with Outstanding Mechanical Properties Manipulated by Supramolecular Interactions

Abstract: Proteinaceous fibers based on spidroins have attracted widespread attention due to their lightweight and mechanically strong properties. Presently, mechanical modulation is mainly dependent on the ultrahigh molecular weight of recombinant proteins. This makes it difficult to construct and express the target proteins. It is thus significant to develop alternative strategies for the fabrication of robust biological fibers. Herein, we demonstrate one new type of engineered protein fibers using electrostatic compl… Show more

“…Next, the metal coordination effect on the adhesion property of K‐NDP glue was investigated (Figure 2 B). To mimic the ratio between Fe 3+ ions and DOPA from mussel adhesive, a molar ratio of metal ions to NDP of 1:3 was chosen [31] . Upon adding Fe 3+ ions in aqueous solution to the K‐NDP coacervate, the color of the complex turned black immediately, indicating the formation of catecholate complexes.…”

[31] Upon adding Fe 3+ ions in aqueous solution to the K‐NDP coacervate, the color of the complex turned black immediately, indicating the formation of catecholate complexes. The absorbance peak at ≈545 nm in the UV‐vis spectrum (Figure S12) confirmed the formation of bis Fe‐catecholate.…”

“…Protein‐based fibers are suitable for practical applications because of their excellent mechanical performance, light weight, good biocompatibility, and biodegradability. [ 59–65 ] Stimuli‐responsive fibers have received tremendous attention over the past decade. [ 66 ] For example, azobenzene‐functionalized cross‐linked liquid‐crystalline fibers are capable of macroscopic movements stimulated by UV light irradiation.…”

“…[18][19][20][21][22] They are generally prepared by combining organic (luminescent dyes or proteins) or inorganic luminophores (quantum dots and lanthanide-containing nanoparticles) with biocompatible polymers. [23][24][25] However, organic luminophores typically suffer from poor photostability, photobleaching, and/or low quantum yields, while biodegradability and toxicity of the inorganic nanoparticle-containing hybrids are of general concern. [26][27][28] In this work, we report our efforts toward a possible solution to the aforementioned challenges by making a new type of biocompatible hybrids composed of a classically cross-linked poly(citrates-siloxane) (PCS) elastomer 29 and surfactant-passivated ultrathin Ln(OH)CO 3 nanowires.…”
