Bioinorganic chemistry is a broad field with multiple branches. In this Highlight Review, the newest excitements in the branch of Bioinorganic Platforms are reviewed. Artificial bioinorganic platforms come in mesmerizing flavors, in particular the following 5 types are the major focus of this Highlight Review. First, single-stranded and double-stranded DNA, RNA, PNA, and their hybrids can be attached onto Au electrodes for in vitro biosensing purposes as well as real-time monitoring of DNA repair processes via magnetoelectrochemistry. Second, Pseudomonas aeruginosa biofilms can be grown interdigitated array (IDA) electrodes to investigate electron transport mechanisms in vivo. Third, protein films can be formed on glassy carbon (GC) electrodes to examine the effect of electrostatics on the redox behavior of metalloenzymes. Fourth, lipid-covered hybrid bilayer membrane (HBM) systems can be constructed to control the thermodynamics and kinetics of proton-coupled electron transfer (PCET) steps important to renewable energy schemes. Fifth, metal complexes can be physisorbed onto highly porous carbon powder as facile oxygen reduction reaction (ORR) catalysts.

用于传感,仿生和能量催化的生物无机平台

生物无机化学是一个具有多个分支的广阔领域。在本次重点回顾中,对生物无机平台分支中的最新兴奋进行了回顾。人工生物无机平台具有令人着迷的风味,特别是以下5种类型是本重点回顾的重点。首先,可以将单链和双链DNA,RNA,PNA及其杂交体连接到Au电极上,以进行体外生物传感以及通过磁电化学实时监测DNA修复过程。第二,可以将铜绿假单胞菌生物膜生长成叉指阵列(IDA)电极,以研究体内电子传输机制。第三,可以在玻璃碳(GC)电极上形成蛋白质膜,以检查静电对金属酶的氧化还原行为的影响。第四,可以构建脂质覆盖的混合双层膜(HBM)系统,以控制对可再生能源计划很重要的质子偶联电子转移(PCET)步骤的热力学和动力学。第五,金属配合物可以作为简便的氧还原反应(ORR)催化剂物理吸附在高度多孔的碳粉上。
