Fig. 6From: Fabrication of polydimethylsiloxane nanofluidic chips under AFM tip-based nanomilling processSchematic representation of AFM tip trajectory during nanomilling process: the machined width of nanochannel (a) is smaller than nanochannel (b), and the dashed ellipses, the black solid ellipses, and the blue arrows represent the finished machining process, the on-going machining process, and the motion direction of AFM tip, respectivelyBack to article page
