Membranes
Membranes are barriers that enable ions, molecules, or particles to pass through in a selective manner. Polydimethylsiloxane (PDMS) is used as a barrier for liquids and as a permeable path for gaseous elements and compounds. One of the characteristics of silicon chemistry is that the presence of the silicon atom…
Microfluidics
Microfluidics is the study of fluids and their behavior on the microscale. Since their introduction in the 1980s, microfluidic devices have been incorporated into a wide variety of applications including chemical analyses, DNA chips, and ink-jet printheads. A result of the small size of microfluidic devices is a reduction of…
