SU-8的光聚合在微球上的金膜（AuFOMs）上进行，所述微球可以在其表面上提供等离子体增强场。强烈的依赖于AuFOMs的表面粗糙度的光聚合反应性进行了观察;粗糙的金表面，而不是平坦的表面上的光聚合显着增强。结果还表明，通过多光子过程的光引发剂的光激发诱导AuFOM表面上，即使与非相干光源。
Photopolymerization of SU-8 was performed on gold films over microspheres (AuFOMs) that can provide plasmon-enhanced fields on their surfaces. Strong dependence of the photopolymerization reactivity on the surface roughness of AuFOMs was observed; the photopolymerization was enhanced significantly on rough gold surfaces rather than flat surfaces. The results also suggested that photoexcitation of the photoinitiator via a multiphoton process was induced on AuFOM surfaces even with an incoherent light source.
