Certain commercial equipment, instruments, or materials are identified in this paper in order to specify the experimental procedure adequately. Such identification is not intended to imply recommendation or endorsement by the National Institute of Standards and Technology, nor is it intended to imply that the materials or equipment identified are necessarily the best available for the purpose.
DL-homocysteine thiolactone hydrochloride (99 %) was purchased from Alfa Aesar and used as received. Triethylamine (TEA), 1,8-diazabicyclo(5.4.0)undec-7-ene (DBU), dansylcadaverine, and 4-bromobenzylamine (BBA) were purchased from Sigma-Aldrich and used as received. 1H,1H-Perfluoro-N-decyl acrylate (PFDA) was purchased from Gelest. Texas Red® C2 maleimide was purchased from Introgen. Silicon wafers (orientation <100>, native oxide) were purchased from University Wafer. The PDMS stamp (5 μm lines spaced by 10 μm) was purchased from Research Micro Stamps. An azo-based trichlorosilane initiator for surface-initiated polymerization was synthesized per literature procedures.34 , 35
