Questions and Answers
  • 1. 
    What is the fundamental limitation of PDMS stamps, or microcontact printing?
    • A. 

      It cannot create complex multicomponent patterns with nanoscale registry

    • B. 

      Creating new master stamps is costly and time consuming.

    • C. 

      PDMS is hydrophobic and tends to absorb some proteins
