Figure 4. Transfer of bilayer by micro-contact printing from corrugated PDMS elastomers onto silicon substrates.

(a) Epifluorescence image of PDMS substrate following micro-contact printing. The image reveals a substantial loss of fluorescence from the PDMS hills, which come in contact with the silicon substrate. (b,c) Atomic force microscopy images (2D rendition, Fig. 4 b and 3D rendition, Fig. 4 c ). The images indicate transferred height of the lipid phase of nm confirming the presence of single bilayer onto the parent PDMS. Note also that nanoscale features of the hill region (see text) are reproduced in the transfer process.
