What is Paper-Based Acoustofluidics?
Paper-based acoustofluidics leverages the unique properties of paper as a microfluidic platform, integrated with acoustic waves to manipulate fluids and particles. Unlike traditional methods, this technique requires minimal resources, making it ideal for point-of-care diagnostics, environmental monitoring, and lab-on-a-chip applications.

How Does It Work?
Key Components
- Paper Substrate: Acts as a natural microfluidic channel, allowing capillary action to move fluids.
- Acoustic Transducers: Generate high-frequency sound waves to manipulate particles within the fluid.
- Particle Separation: Acoustic forces selectively move particles based on size, density, or compressibility.
The Separation Process
When acoustic waves pass through the paper substrate, they create pressure nodes and antinodes. Particles within the fluid experience acoustic radiation forces, causing them to migrate to specific regions on the paper. This enables precise separation without external pumps or complex setups.

- Cost-Effective: Paper is inexpensive and widely available.
- Portable: Lightweight and easy to transport for field applications.
- Scalable: Can be adapted for small-scale or large-scale separations.
- Eco-Friendly: Biodegradable paper reduces environmental impact.
