通过生物工程，硅蛋白酶可以携带含硫醇的金亲和标签（Cys-tag），在最短的时间内直接固定在金载体上，而无需事先进行表面功能化。通过微接触印刷，在金表面形成了明确的硅酸盐微图案，促进了随后酶控光催化活性TiO(2)的合成。
The enzyme silicatein has been bioengineered to carry a thiol-bearing Au-affinity tag (Cys-tag) for direct immobilization on gold carriers in shortest time without the need for prior surface functionalization. Through microcontact printing, defined silicatein micropatterns were created on gold surfaces, facilitating the subsequent enzymatically controlled synthesis of photocatalytically active TiO(2).
