In this article, we present a unique combination of techniques focusing on the immobilization of noble metal nanoparticles into a honeycomb polystyrene pattern prepared with the improved phase-separation technique. The procedure consists of two main steps: the preparation of the honeycomb pattern (HCP) on a perfluoroethylenepropylene substrate (FEP), followed by an immobilization procedure realized by the honeycomb pattern's exposure to an excimer laser in a noble metal nanoparticle solution. The surface physico-chemical properties, mainly the surface morphology and chemistry, are characterized in detail in the study. The two-step procedure represents the unique architecture of the surface immobilization process, which reveals a wide range of potential applications, mainly in tissue engineering, but also as substrates for analytical use.
在本文中，我们展示了一种独特的技术组合，重点是将贵金属纳米颗粒固定到采用改进相分离技术制备的蜂窝状聚苯乙烯图案中。该过程包括两个主要步骤：在全氟乙烯丙烯基板（FEP）上制备蜂窝图案（HCP），然后通过将蜂窝图案暴露于贵金属纳米颗粒溶液中的准分子激光来实现固定过程。在该研究中，对表面物理化学性质，主要是表面形态和化学性质进行了详细表征。这个两步过程代表了表面固定过程的独特结构，揭示了广泛的潜在应用，主要在组织工程领域，也可作为分析用途的基板。
