Relationship between a nanochannel height, b nanochannel width, and transfer parameters (various weight ratio of PDMS) during second transfer, where the channel molds were fabricated with a normal load of 25 μN and a frequency of 100 Hz, and c typical AFM image and d corresponding cross-section of the nanochannel obtained from wall III at a weight ratio of 10:1 during second transfer
