  1. PUA molding  UV curable poly(urethane acrylate) used instead of PDMS (poly(dimethyl siloxane)) mechanical properties of PDMS makes it difficult to create sub 100 nm features low elastic modulus, high compressibility photo-cross-linkable PEG dimethacrylate features as small as 50 nm could be created through capillary action the PEG fills the voids of the mould then cured through exposure to UV

  2. PEG nanopillars for protein and cell adsorption studies 150 nm @ base 50 nm @ peak 500 nm spaces 250-300 nm height adhered fibroblast filopodia growth along nanopillar structure
