Glass

Definition

Glass is a solid material made by heating silica and other compounds to high temperatures, resulting in a transparent or translucent substance. Its unique properties, such as optical clarity, chemical resistance, and mechanical strength, make it widely used in various applications, including nanofluidics, where it serves as a medium for the manipulation of fluids at the nanoscale.

5 Must Know Facts For Your Next Test

1. Glass is favored in nanofluidics due to its excellent optical properties, allowing researchers to observe fluid behavior under a microscope.
2. The smooth surface of glass minimizes friction and enables more precise control of fluid flow at the nanoscale.
3. Glass can be treated chemically or coated to modify its hydrophilicity or hydrophobicity, influencing how fluids behave within nanofluidic channels.
4. Thermal properties of glass can be tailored to enhance the performance of nanofluidic devices under various temperature conditions.
5. Using glass in nanofluidics can help reduce contamination risks since it is chemically inert and does not react with most fluids.

Review Questions
