In this study, an innovative large-scale synthesis of graphene nanoribbons (GNRs) with the eco-friendly unzipping process (only 0.1 mL H₂SO₄ acid solution for 1.0 mg carbon nanotube) was proposed. Nearly 100% yields of carbon nanotube derived GNRs was achieved by the proposed procedure. Through the longitudinal unzipping method, abundant oxygen-based functional groups were formed at the edges of GNRs, thus offering tremendous advantages for material synthesis and design. Furthermore, the reduction of platinum precursor to form platinum nanoparticles (PtNPs) can be facilitated by the functional groups on GNR surface for specific sensing. In fact, PtNPs played a role in connecting nodes to synergize the synthesized composite. The composite of PtNPs/GNRs could be further utilized as non-enzymatic biosensing materials against either oxidative or reductive analyte. Two essential biomarkers, namely hydrogen peroxide (H₂O₂) and β-nicotinamide adenine dinucleotide (NADH), were chosen to prove the feasibility of the proposed biosensors. From the experimental results of the amperometric analysis, sensitivities of the modified PtNPs/GNRs electrode toward H₂O₂ (378.5 µA/mM/cm^–2) and NADH (724.3 µA/mM/cm^–2) were obtained. The composite of PtNPs/GNRs has been verified to be a potential material for electrochemical biosensing with attractive sensitivity, selectivity, and stability.

在这项研究中，创新的大规模合成石墨烯纳米带（GNR）具有生态友好的解压过程（仅0.1 mL H ₂ SO ₄提出了1.0 mg碳纳米管的酸性溶液）。通过提出的程序，碳纳米管衍生的GNR的收率接近100％。通过纵向解压缩方法，GNRs的边缘形成了丰富的基于氧的官能团，从而为材料合成和设计提供了巨大的优势。此外，可以通过GNR表面上的官能团促进铂前体的还原以形成铂纳米颗粒（PtNPs），以进行特定感测。实际上，PtNP在连接节点以协同合成合成物方面发挥了作用。PtNPs / GNRs的复合材料可进一步用作抗氧化或还原分析物的非酶生物传感材料。两个基本的生物标志物，即过氧化氢（H ₂ O ₂）和β-烟酰胺腺嘌呤二核苷酸（NADH）被选择来证明所提出的生物传感器的可行性。根据安培分析的实验结果，获得了修饰的PtNPs / GNRs电极对H ₂ O ₂（378.5 µA / mM / cm ^–2）和NADH（724.3 µA / mM / cm ^–2）的敏感性。PtNPs / GNRs的复合物已被证明是电化学生物传感的潜在材料，具有诱人的灵敏度，选择性和稳定性。
