The attachment of cells to surfaces is inherently a function of surface composition. The most commonly used materials in microfluidic device fabrication are silicon dioxide (glass), poly (dimethylsiloxane) (PDMS), and silicon. PDMS and silicon are hydrophobic and this characteristic can be exploited to coat these surfaces with ligands by adsorption. 

Polysiloxanes are inorganie polymers that eontain alternate silieon and oxygen atoms in their baekbone [1-6]. While the silicon atom has two side-groups the oxygen atom carries none. In this regard they are similar to polyphosphazenes that we have seen in Chap. 3. The most widely studied polymer of this family is poly(dimethylsiloxane) (PDMS) which contains methyl groups as the substituents on silicon. PDMS is isoelectronic with poly(isobutylene) as well as poly(dimethylphosphazene) although its properties are dramatically different (Fig. 6.1).
