 Stripe patterns prepared at speeds of 60, 70, and 100 µm/s created width and groove spacings of 2.2 and 6.1 µm, 3.6 and 8.4 µm, and 4.3 and 12.7 µm, respectively; the range of heights for the ridges was 50–100 nm.Tsuruma, Tanaka et al.demonstrated that embryonic neural cells cultured on film coated with poly-L-lysine attached and elongated parallel to poly(ε-caprolactone)/chloroform solution (1g/L) stripes with narrow pattern width and spacing (width
