Technical Details & Test Data

SAMs (Self-Assembled Monolayers)

They can be applied neat or in solution via conventional lithography techniques to form SAMs. SAM is a layer of amphiphilic molecules created by the chemisorption onto a metal oxide, precious metal surface, plastic or nanoparticle substrates, followed by the 2-dimensional alignment of hydrophobic groups to form a structures single monolayer. The surface can be selectively modified to achieve the desired antisticktion, mechanical and chemical properties for microelectromechanical systems (MEMS) and nanoelectromechanical systems (NEMS).
