【摘要】 分子的自装配是自然界中一种普遍存在的现象。一些具备亲水性和疏水性氨基酸残基交替和离子自身互补两种特征的肽段能通过这种自装配作用形成纳米纤维进而形成可见的膜结构。这种膜具有很好的稳定性,能使细胞在其上附着、生长和分化,从而为组织修复、组织工程提供了一个极有前景的生物材料。更多还原

【Abstract】 Self-assembly of molecules is a ubiquitous phenomenon in the nature.Some peptides,which are characterized by both amino acid sequences of alternating hydrophobic and hydrophilic side groups and ionic self-complementary,can form the nanofibers,and then,form the macromembrane.This novel biomaterial shows good stability,and is a scaffold for attachment,growth and differentiation of cells.It is a prospective biomaterial for tissue repair and tissue engineering.更多还原
