The choice of materials for creating microchannels depends on the application. Common materials include silicon, glass, and polymers such as PDMS (Polydimethylsiloxane). Silicon is widely used due to its mechanical strength and compatibility with existing semiconductor technologies. Glass offers excellent optical properties and chemical resistance, making it suitable for biological and chemical applications. Polymers like PDMS are favored for their flexibility, ease of fabrication, and cost-effectiveness.
