摘要: Methods for making biomaterials for use as a tissue sealant, kits containing precursors for forming the biomaterials, and the resulting biomaterials are described herein. The biomaterials are formed from a composition comprising at least a first and a second precursor molecule, wherein:
i) the first precursor molecule is a poly(ethylene glycol) based polymer having x nucleophilic groups selected from the group consisting of thiol or amino groups, wherein x is equal to 2 or greater than 2, preferably 3, 4, 5, 6, 7 or 8;
ii) the second precursor molecule is of the general formula:
A-[(C 3 H 6 O) n -(C 2 H 4 O) m -B] i
wherein m and n are integers from 1 to 200
i is greater than 2, preferably 3, 4, 5, 6, 7 or 8
A is a branch point
B is a conjugated unsaturated group.摘要翻译: 用于制备用作组织密封剂的生物材料的方法,包含用于形成生物材料的前体的试剂盒以及所得生物材料在本文中描述。 生物材料由包含至少第一和第二前体分子的组合物形成,其中:i)第一前体分子是具有选自硫醇或氨基的x个亲核基团的聚(乙二醇)基聚合物, 其中x等于2或大于2,优选3,4,5,6,7或8; ii)第二前体分子具有以下通式:ƒ€ƒ€ƒ€ƒ€ƒ€ƒA - [(C 3 H 6 O)n - (C 2 H 4 O)m -B ]其中m和n是1至200i的整数大于2,优选3,4,5,6,7或8 A是分支点B是共轭不饱和基团。
