如果没有生物粘附输送装置,复杂的化合物通常会被粘液层从粘膜组织中降解或清除。虽然已经在水性环境中研究了一些化学改性的微结构表面,但尚未研究仅由几何形状引起的粘附力。硅纳米线包被的珠子在剪切力下表现出明显比带有靶向剂的珠子更好的粘附力,并且可以将剥离力增加100倍。我们已经证明,纳米线涂层与上皮生理学相结合,可以显着增加粘膜条件下的粘附力。
Without bioadhesive delivery devices, complex compounds are typically degraded or cleared from mucosal tissues by the mucus layer. While some chemically-modified, micro-structured surfaces have been studied in aqueous environments, adhesion due to geometry alone has not been investigated. Silicon nanowire-coated beads show significantly better adhesion than those with targeting agents under shear, and can increase the lift-off force 100-fold. We have shown that nanowire coatings, paired with epithelial physiology, significantly increase adhesion in mucosal conditions.
