DNA是生物体内的主要遗传物质,由4种核苷酸A、T、G、C组成.由于它所具有的一些独特性质,使得DNA在纳米器件、生物传感器等的研究中得到越来越多的应用.i-DNA是一段包含胞嘧啶核苷酸(C)的单链DNA片段,当C部分质子化时,由于C和C~+之间的氢键作用,会形成一个四聚体结构.目前,已有多篇文献报道了基于i-DNA的纳米器件~([1~3]). 相似文献

By aiming the pump wavelength of the laser diode to the absorption peak at 811 nm of the (Nd 0.005 Lu 0.4975 Y 0.4975 ) 2 SiO 5 (Nd:LYSO) crystal, an efficient dual-wavelength operation at 1 075 and 1 079 nm is obtained. The maximum output power is 702 mW when the incident pump power is 2.53 W, corresponding to an optical conversion efficiency of 27.7% and a slope efficiency of 37.0% 相似文献
