PDMS (Polydimethylsiloxane) Sylgard 184 for Microfluidic Chips
Two-part silicone elastomer (Sylgard 184, Dow) used for soft-lithography fabrication of microfluidic chips in point-of-care diagnostic devices. The de facto industry standard for lab-on-chip device manufacturing. Dow's Sylgard 184 dominates with an "unmatched competitive advantage." Transition to alternative materials is slow due to established workflows.
