Tuning the properties of soy protein isolate-based adhesive using various sustainable additives.

This work investigates the adhesive property of Soy Protein Isolate (SPI) polymer solution by studying mechanical properties of composites formed using waste wood granules and SPI solutions. To improve the adhesive strength of SPI solution, Carboxymethyl Cellulose Sodium (NaCMC) was mixed (in the weight ratios of 9:1 and 8:2) due to its strong gel formation capabilities. The adhesive performance of these composites was further investigated in the presence and absence of non-toxic additives, including sorbitol (SOR) and stearic acid (SA).

Smart self-tightening surgical suture from a tough bio-based hyperbranched polyurethane/reduced carbon dot nanocomposite.

Design and fabrication of a smart bio-based polymeric material with potent biocompatibility and high performance still remain a challenge in the biomedical realm. In this context, a potential smart suture was fabricated from starch modified hyperbranched polyurethane (HPU) nanocomposites with different weight percentages of reduced carbon dots for the first time. The desired mechanical (tensile strength: 32.

High performance bio-based hyperbranched polyurethane/carbon dot-silver nanocomposite: a rapid self-expandable stent.

Development of a bio-based smart implantable material with multifaceted attributes of high performance, potent biocompatibility and inherent antibacterial property, particularly against drug resistant bacteria, is a challenging task in biomedical domain. Addressing these aspects at the bio-nano interface, we report the in situ fabrication of starch modified hyperbranched polyurethane (HPU) nanocomposites by incorporating different weight percentages of carbon dot-silver nanohybrid during polymerization process. This nanohybrid and its individual nanomaterials (Ag and CD) were prepared by facile hydrothermal approaches and characterized by various instrumental techniques.
