Hydrogels of dialdehyde starch and gelatin cross-linked with potential application as tissue adhesives.

Invasive surgical methods are the current standard for hemostasis and wound closure. In recent years, injectable hydrogels prepared from natural biomacromolecules have shown promise as tissue adhesives to overcome their shortcomings due to their high hydrophilicity and biocompatibility, but the inherent properties of unmodified biomolecules remain a major challenge in their application. In this paper, a hydrogel (DS/Gel-CDH) with self-healing, injectable and adhesive functions was constructed by Schiff base crosslinking between carbonyl hydrazide modified gelatin (Gel-CDH) and dialdehyde starch (DS).

Structural and physicochemical properties of corn starch modified by phosphorylase b, hexokinase and alkaline phosphatase.

To improve the functional properties of corn starch, phosphorylase b (PB), hexokinase (HK), and alkaline phosphatase (AP) were used to produce enzyme-modified starches (PBMS, HKMS, and APMS). The results showed that enzyme-modified starches had different phosphorus contents and degrees of substitution. The presence of PO bonds and P-O-C bonds further demonstrated that phosphate groups were grafted into starch.

Impact of starch amylose and amylopectin on the rheological and 3D printing properties of corn starch.

This study evaluated the influence of the amylose and amylopectin on the physicochemical properties and printing performance of corn starch gels. Amylose in starch-based gels enhances their storage modulus and the support performance of printed products by promoting the formation of cross-linked gel structures and crystalline structures. However, the higher amylose content in starch gels makes extrusion difficult, resulting in intermittent extrusion in 3D printing.
