What is Paper-Based Acoustofluidics?
Paper-based acoustofluidics integrates paper microfluidics with acoustofluidics, a technique that uses acoustic waves to manipulate fluids and particles. Paper serves as a low-cost, biodegradable substrate, while acoustic waves provide precise control over particle movement. This hybrid approach eliminates the need for external pumps or complex equipment, making it ideal for resource-limited settings. (acoustofluidics, paper microfluidics, particle separation)
How Does Paper-Based Acoustofluidics Work?
The process involves applying acoustic waves to a paper substrate containing a fluid sample. These waves create pressure gradients that selectively move particles based on their size, density, or compressibility. The porous nature of paper enhances fluid flow, allowing for efficient separation without additional power sources. This method is particularly effective for sorting biological samples, such as cells or proteins. (acoustic waves, particle manipulation, paper substrate)
