Adhesive Bioinks
In article number 2205078, Xingcai Zhang, Ximu Zhang, Yu Shrike Zhang, and co‐workers develop an adhesive bioink using a multicomponent bioink containing skin secretion of Chinese giant salamander. The bioink exhibits favorable cohesion to allow faithful fabrication in wet conditions, while simultaneously showing good adhesion to a variety of surfaces of different chemical properties...
Three‐dimensional (3D) bioprinting is driving significant innovations in biomedicine over recent years. Under certain scenarios such as in intraoperative bioprinting, the bioinks used should exhibit not only cyto/biocompatibility but also adhesiveness in wet conditions. Herein, an adhesive bioink composed of gelatin methacryloyl, gelatin, methacrylated hyaluronic acid, and skin secretion of Andrias davidianus...
High‐performance hemostasis has become increasingly essential in treating various traumas. However, available topical hemostats still have various drawbacks and side‐effects. Herein, hemostatic powders derived from the skin secretion of Andrias davidianus (SSAD) with controllable particle size are prepared using feasible frozen‐ball milling following lyophilization for hemorrhage‐control. Scanning electron microscopy,...
Highly reactive copper‐dihydride clusters, [Cu15(H)2(S2CNR2)6(C2Ph)6](PF6) {R =nBu (1H), nPr (2H), iBu (3H)}, are isolated during the reaction of [Cu28H15{S2CNnBu2}12](PF6) with ten equivalents of phenylacetylene. They are found to be intermediates in the formation of the earlier reported two‐electron superatom [Cu13(S2CNR2)6(C2Ph)4]+. Better yields are obtained by reacting dithiocarbamate sodium...
