Mechanical and Physical Properties of Recombinant Spider Silk Films Using Organic and Aqueous Solvents
Spider silk has exceptional mechanical and biocompatibility properties. The goal of this study was optimization of the mechanical properties of synthetic spider silk thin films made from synthetic forms of MaSp1 and MaSp2, which compose the dragline silk of Nephila clavipes. We increased the mechanical stress of MaSp1 and 2 films solubilized in both HFIP and water by adding glutaraldehyde and t...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولInterfacial rheological properties of recombinant spider-silk proteins.
Freestanding protein films are interesting for many applications ranging from microencapsulation to tissue engineering. Here, the authors use interfacial rheology to characterize the adsorption kinetics and the rheology of spider-silk films formed at an oil water interface. The high surface activity of the engineered spider-silk proteins results in a fast formation of highly stable films, which...
متن کاملNovel Assembly Properties of Recombinant Spider Dragline Silk Proteins
Spider dragline silk, which exhibits extraordinary strength and toughness, is primarily composed of two related proteins that largely consist of repetitive sequences. In most spiders, the repetitive region of one of these proteins is rich in prolines, which are not present in the repetitive region of the other. The absence of prolines in one component was previously speculated to be essential f...
