“…Previous research has proved the modeling ability of collagen fiber and the feasibility of molecules separation. Li et al [15] synthesized a skinsimulated TFC membrane via a vacuum-assisted IP method for dye/salt separation. With the decoration of collagen fibril, the optimized membrane possessed a water permeability up to 84.7 L h −1 m −2 bar −1 and outstanding dyes rejections (> 98.5%).…”

Biomass-based membranes have attracted increasing attentions due to their cheap and sustainable advantages. In this work, a novel thin-film composite (TFC) nanofiltration (NF) membrane was fabricated through a facial interfacial polymerization (IP) process by initiate the crosslinking reaction between collagen fibers (CFs) and tannic acid (TA). The increased TA concentrations endowed the TFC membrane with a higher crosslinking degree, a thicker active layer and a rougher top surface. At optimized condition with 0.60 mg TA decoration, the TFC-3 membrane exhibited a high water permeability of 23.49 L m−2 h−1 bar−1 with high rejections above 98.0% for congo red, reactive blue 19, coomassie blue G-250, and methyl blue. Furthermore, the membrane preserved remarkable salt retentions (93.3% for Na2SO4, 83.4% for MgSO4, 36.2% for MgCl2, and 26.4% for NaCl) and satisfying operation stability. This facial fabrication method offered a new insight to employ biomass for molecular precise separation. Graphical abstract

“…Type I collagen was the most dominant type of collagen . ELISA kits were used to detect the secretion of type I collagen and hyaluronic acid (HA) in mouse skin and serum, and the results showed that low- and high-dose GHK-Cu/BMa (groups A and B) increased the content of type I collagen in the skin by 25.4 and 56%, respectively, and in serum by 44.8 and 81.5%, respectively (Figures d and S8).…”

The application of bioactive polypeptides has become a challenge in the pharmaceutical industry. Copper glycyl-histidine-tripeptide (GHK-Cu) exerts various biological effects, including antioxidation, promotion of cell proliferation, and enhancement of repair. However, its clinical application is restricted by its hydrophilicity and severe demands with respect to the delivery conditions. Therefore, for the purpose of its application and of resolving the existing issues of GHK-Cu, we designed and developed a new local delivery system based on green ionic liquids (ILs) by combining the density functional theory (DFT) and adequate experiments. The system integrates the advantages of the ILs and GHK-Cu, which not only stabilizes GHK-Cu and greatly enhances its transdermal absorption rate but also has a synergistic amplification effect. Cell and animal experiments show encouraging effects on cell proliferation, antioxidation, and collagen synthesis, whereas human efficacy tests show the benefits of improving skin repair ability and antiaging, antiwrinkle, and moisturizing properties. The bio-based ILs system developed in this study provides a simple and efficient method for the clinical application of GHK-Cu and a novel method for the application of polypeptides.

Further increase of the ATP proportion elicited reduced intensities of C�N.…”

The compromise of permeability and selectivity is a central paradigm in gills by which the gill filaments perform rapid intake of oxygen (O 2 ) and rejection of carbon dioxide (CO 2 ) in a benign physiological environment. Such an efficient separation in nature is a key dogma in designing biomimetic separation systems, yet the fundamental challenge of the permeability−selectivity trade-off still remains a nascence. In this study, we report a gill-inspired diffusion dialysis membrane for acid recovery from heavy metal wastewater with a high permeation efficiency of acid ions (H + ) and robust rejection of cadmium ions (Cd 2+ ) plus stable performances against repeated separations. This membrane was fabricated by vacuum filtration of a nanocomposite regime featuring natural protein nanoparticles attached to the rod-shaped attapulgites. The stacking of such anisotropic building blocks endowed the membranes with capacious channels for H + transport, while the electropositivity of proteins enabled robust rejection of Cd 2+ . The enhanced separation performance of this membrane mimicked the art of gills with gill arches, enlarging the specific area of gill filaments arresting O 2 but expelling CO 2 . As a result, the membrane exhibited a high H + dialysis coefficient (0.049 m•h −1 ) and H + /Cd 2+ selectivity (S H/Cd = 23.3) with excellent long-term operational stability and general applicability (S H/Cu = 26.3, S H/Pb = 18.1, S H/Ca = 23.3, and S H/Mg = 18.6) suitable for practical applications.
