Fig. 1From: Sensitive and Selective Detection of HIV-1 RRE RNA Using Vertical Silicon Nanowire Electrode ArraySEM and TEM images of the synthesized SiNWs. a, b SEM image of vertical SiNWs (tilted by 30°). c Typical low-magnitude TEM image and d HRTEM image of a SiNW. The inset of part c shows a SAED pattern of the NW. The inset SAED pattern is related with a crystal plane of the NW, and the NW growth direction spots express the [111] crystal planes. It indicates that SiNW has [111] growth directionBack to article page
