Emerging on-chip surface acoustic wave technology for small biomaterials manipulation and characterization

Area of Science:

• Acoustics
• Biomaterials Science
• Micro/Nanosystems Engineering

Background:

• Surface acoustic waves (SAW) are sound waves on elastic material surfaces, offering versatile energy control.
• SAW acts as both an actuator for micro/nanoscale manipulation and a sensor for environmental changes.
• On-chip SAW technology integrates SAW with lab-on-a-chip (LOC) for micro/nanosystems, showing biocompatibility for biomaterials research.

Purpose of the Study:

• To review recent advances in on-chip SAW technology for biomaterials manipulation and characterization.
