Chemical Peels For Molecular Films
A new method peels molecules off surfaces to create patterned arrays, rather than printing them onto surfaces as in conventional soft lithography (Science, DOI: 10.1126/science.1221774).
By removing patches of molecules, the technique can generate molecular arrays with 40-nm features. That resolution is higher than is possible with many soft lithography techniques, which add molecules to surfaces. Furthermore, compounds printed onto bare substrates by conventional methods tend to spread, . . .
