| 1 | 聚吡咯氧化石墨烯修饰的神经微电极阵列显示文摘利用电化学方法,在多通道神经微电极阵列芯片上制备聚吡咯氧化石墨烯薄膜材料,并对该材料的电化学行为进行了分析。对神经微电极阵列芯片采用计时电压法探究,确定了定向修饰聚吡咯氧化石墨烯薄膜的最佳电沉积条件。微电极阵列芯片为多通道实时检测神经细胞的电生理和电化学信号提供了一种新的器件,但其检测灵敏度、信噪比需进一步的提高。将聚吡咯氧化石墨烯的平面微电极阻抗值降低了92.1%,且提高了对多巴胺循环伏安响应的灵敏度,对神经电生理信号和电化学信号的检测具有重要意义。 | 王力 蒋庭君 石文韬 宋轶琳 徐声伟 蔡新霞 | 2015 | 电子科技大学学报2015，44，4： | 2 |
| 2 | Nano-opto-electronics for biomedicine显示文摘Nano-opto-electronics for biomedicine is a developing interdisciplinary field. Related areas of this field are tried to be classified and outlined herein. Progresses in the different areas were reviewed based on the research development of the invited experts. Prospects of nano-opto-electronics for biomedicine are discussed. | GU Ning LI Yan WANG Meng CAO Min | 2013 | Chinese Science Bulletin2013，58，21： | 0 |
| 3 | Dopamine detection using a patch-clamp system on a planar microeletrode array electrodeposited by polypyrrole/graphene nanocomposites显示文摘To achieve a dopamine(DA)response with high sensitivity and high signal-to-noise ratio(S/N)with a patch-clamp system,polypyrrole/graphene(PPy/GR)nanocomposites were steadily electrodeposited by an electrochemical method on a planar microelectrode array(pMEA)fabricated by a standard micromachining process.The electrodeposition process was carried out by chronopotentimetry measurement scanning from 0.1 to 0.8 C/cm2at the current of 2 mA;0.5 C/cm2was found to be optimal.The pMEA modified by PPy/GR at the 0.5 C/cm2exhibits remarkable properties;for instance,the standard deviation(SD)decreases from 8.4614×10-11to 5.62×10 11A,reduced by 33.52%,and the sensitivity increases from 2566.88 to 76114.65μAmMcm-2,29.65 times higher than the bare Pt(platinum).A good linear relationship between the current and DA concentration in the range of 0.30 to 61.71μm was obtained,with a correlation coefficient of 0.997.The sensor is meaningful for neuroscience research and the treatment of neurological diseases. | WANG Li JIANG TingJun SONG YiLin SHI WenTao CAI XinXia | 2014 | Science China(Technological Sciences)2014，57，2： | 0 |
