• and six microcantilevers with functional Au layers for mPEG–SH grafting. For measurements of the PEG-brush collapse using an internal reference, two microcantilevers in the array were blocked with EG4–C11–SH self-assembled monolayers (SAMs) using an ink-jet spotter as described above. To coat the
