Multifunctional and biodegradable nanostructured hybrid interfaces based on biopolymers are potentially useful in many applications in catalysis, bioanalytical sensing and nanomedicine. Herein, we report the engineering of multifunctional hybrid films by assembling adhesive biological nanoparticles composed of lipoate-conjugated phytoglycogen (L-PG). These nano building blocks possess adhesive properties, arising from their amphiphilic nature, and reactive functional disulfide groups. The assembly of L-PG on surfaces enabled the rapid and conformal deposition of a thin film on substrates of varying chemical composition and wettability. The L-PG films showed negligible cytotoxicity and moderate stability under different conditions but displayed enzyme-mediated degradability. In addition, metal nanoparticles were embedded into the L-PG layers to build up multilayered hybrid films. Specifically, gold and silver nanoparticle-loaded L-PG multilayered films with catalytic and surface-enhanced Raman scattering properties were prepared. Finally, we highlight the versatility of the present approach to engineer multifaceted interfaces for catalysis and sensing applications.

使用粘性糖原纳米颗粒的纳米工程多功能杂化界面。
基于生物聚合物的多功能且可生物降解的纳米结构杂化界面可能在催化，生物分析传感和纳米医学的许多应用中有用。在这里，我们报告通过组装由硫辛酸酯共轭植物糖原（L-PG）组成的粘合剂生物纳米粒子的多功能杂化膜的工程。这些纳米构件具有两亲性和反应性功能性二硫键基团的粘合特性。L-PG在表面上的组装使薄膜能够快速而保形地沉积在化学成分和润湿性不同的基材上。L-PG膜在不同条件下显示出微不足道的细胞毒性和中等稳定性，但显示出酶介导的降解性。此外，将金属纳米颗粒嵌入L-PG层中，以构建多层杂化膜。具体地，制备了具有催化和表面增强的拉曼散射性质的负载金和银纳米颗粒的L-PG多层膜。最后，我们强调了本方法在催化和传感应用中设计多面接口的多功能性。
