We report the biosynthesis of size confined palladium nanoparticles (Pd-NPs). The 2–3 nm size Pd-NPs were grown in 12-mer protein stable protein 1 (SP1), which serves as a template for the NP formation. We further show that by controlling the protein expression levels in the cells we can alter the cells’ catalytic activity. The in vivo grown Pd-NPs were utilized in a hydrogenation reaction, converting acetylene feedstock into ethylene and ethane. The presented concept can be further used for a wide range of applications by exploiting the synergetic effect of the biotic elements with the abiotic ones.

体内和体外蛋白质介导的钯纳米粒子合成用于氢化反应。

我们报告了尺寸受限的钯纳米粒子（Pd-NPs）的生物合成。2–3 nm大小的Pd-NPs在12-mer蛋白稳定蛋白1（SP1）中生长，该蛋白可作为NP形成的模板。我们进一步表明，通过控制细胞中蛋白质的表达水平，我们可以改变细胞的催化活性。在体内生长的Pd纳米粒被用在氢化反应中，乙炔原料转化成乙烯和乙烷。通过利用生物元素与非生物元素的协同作用，提出的概念可以进一步用于广泛的应用。
