首次合成了来自磨碎樱桃（Physalis peruviana）外壳生物质的具有高密度缺陷位点的碳纳米板，用于构建先进的电化学传感平台。研究了不同分子（铁氰化钾、β-烟酰胺腺嘌呤二核苷酸、过氧化氢、肾上腺素和多巴胺、四种游离DNA碱基（鸟嘌呤、胸腺嘧啶、胞嘧啶和腺嘌呤）、半胱氨酸、抗坏血酸、L-色氨酸、尿酸和对乙酰氨基酚）的混合物在生物质衍生的磨碎樱桃壳衍生的碳纳米板（BG-CNP）上的电化学响应修饰玻璃碳（GC）（BG-CNPs/GC）电极，比GC电极表现出更高的电催化活性。特别是，与碳纳米管修饰的GC（CNTs/GC）和GC电极相比，BG-CNPs/GC电极对过氧化氢（H2O2）表现出非常强的电催化响应，这表明在检测人尿液中的H2O2以及监测活细胞释放的H2O2方面具有巨大的潜在可行性。所有结果表明，BG-CNPs 是一种有前途的碳材料，可用于开发先进的电化学传感平台，具有从伏安传感到电流传感和 DNA 传感等多功能应用。 (C) 2017 Elsevier B.V. 保留所有权利。
For the first time, the carbon nanoplates with high density of defective sites derived from the biomass of ground cherry (Physalis peruviana) husks was synthesized for the construction of an advanced electrochemical sensing platform. Electrochemical responses of different molecules (potassium ferricyanide, beta-nicotinamide adenine dinucleotide, hydrogen peroxide, epinephrine and dopamine, the mixture of four free DNA bases (guanine, thymine, cytosine and adenine), cysteine, ascorbic acid, L-tryptophan, uric acid and acetaminophen) were studied at the biomass derived ground cherry husks derived carbon nanoplates (BG-CNPs) modified glassy carbon (GC) (BG-CNPs/GC) electrode, which shows higher electrocatalytic activities than GC electrode. Especially, the BG-CNPs/GC electrode exhibits remarkably strong electrocatalytic response toward hydrogen peroxide (H2O2) compared with carbon nanotubes modified GC (CNTs/GC) and GC electrodes, indicating the great potential feasibility in the detection of H2O2 in human urine as well as the monitoring of H2O2 released from the living cells. All the results indicate that BG-CNPs is a promising carbon material which could be utilized to develop an advanced electrochemical sensing platform with multifunctional applications ranging from voltammetric sensing to amperometric sensing and DNA sensing.
