This
paper demonstrates a facile method to achieve high yield and
uniform fabrication for the transfer printing of nanoplasmonic structures
on a flexible substrate by providing novel understanding on adhesion
layers. The mercapto alkyl carboxylic acids and the alkyl dithiols
are used as functionalized adhesion layers and further optimized by
controlling the terminal group as well as the length and composition
of the functionalization on flat and nanostructured gold surfaces.
Our approach of optimized adhesion has been successfully implemented
to the transfer printing of functionalized gold nanostructure arrays,
thus producing much higher yield of 97.6% and uniform fabrication
of nanostructures on a flexible substrate and enabling applications
such as flexible nanoplasmonic devices and biosensing platforms.
