1Facile,Noncovalent Decoration of Graphene Oxide Sheets with Nanocrystals显示文摘Facile dry decoration of graphene oxide sheets with aerosol Ag nanocrystals synthesized from an arc plasma source has been demonstrated using an electrostatic force directed assembly technique at room temperature.The Ag nanocrystal-graphene oxide hybrid structure was characterized by transmission electron microscopy(TEM)and selected area diffraction.The ripening of Ag nanocrystals on a graphene oxide sheet was studied by consecutive TEM imaging of the same region on a sample after heating in Ar at elevated temperatures of 100°C,200°C,and 300°C.The average size of Ag nanocrystals increased and the number density decreased after the annealing process.In particular,migration and coalescence of Ag nanocrystals were observed at a temperature as low as 100°C,suggesting a van der Waals interaction between the Ag nanocrystal and the graphene oxide sheet.The availability of affordable graphene-nanocrystal structures and their fundamental properties will open up new opportunities for nanoscience and nanotechnology and accelerate their applications.Ganhua Lu Shun Mao Sungjin Park Rodney S.Ruoff Junhong Chen 2009Nano Research2009,2,3:13
2Highly Sensitive Protein Sensor Based on Thermally-Reduced Graphene Oxide Field-Effect Transistor显示文摘我们报导一只高度敏感的地效果晶体管(联邦货物税) 的制造用减少 thermally 的 graphene 氧化物(TRGO ) 的生物传感器有抗体结合的金 nanoparticle (NP ) 的表 functionalized。探查抗体通过 Au NP 在 TRGO 表的表面上被标记,蛋白质绑定(免疫球蛋白 G/IgG 和反免疫球蛋白 G/anti-IgG ) 的电的察觉被联邦货物税和直接电流(dc ) 完成大小。蛋白质绑定事件在 TRGO 表的电阻导致了重要变化,它被叫作传感器反应。在 TRGO 表上的传感器和抗体 areal 密度中的 TRGO 基础电阻上的传感器反应的依赖系统地被学习,从哪个有传感器参数的传感器反应的关联被发现:传感器反应与更大的 TRGO 基础电阻和更高的抗体 areal 密度是更重要的。新奇生物传感器的察觉限制在 0.2 ng/mL 水平附近,它在报导的碳的最好之中基于 nanomaterial 的蛋白质传感器和罐头被调节传感器结构进一步优化。Shun Mao Kehan Yu Ganhua Lu Junhong Chen 2011Nano Research2011,4,10:6
