通过用于声学纳米流体的尼奥布精锂结合表面声波驱动纳米高通道的制造

Executive Industry Relevance

Nanofluidic systems enable precise manipulation of biomolecules and nanoparticles at scales relevant to single-molecule biophysics and high-throughput screening. Integrating surface acoustic wave actuation with nanoscale channels provides a label-free, dynamically tunable platform for fluid control, reducing reliance on external pumps and valves. This approach supports early-stage target validation by allowing real-time observation of molecular interactions under physiologically relevant shear and confinement conditions.

• Strategic Value: Improves capital efficiency by enabling early detection of formulation or binding liabilities, reducing late-stage failure risk.
• Portfolio Impact: Supports risk-adjusted prioritization by delivering early, quantitative data on target engagement under physically relevant conditions.

Implementation Considerations

• Requires expertise in micro/nanofabrication, surface chemistry, and acoustic actuation systems.
• Depends on access to cleanroom facilities, sputter deposition, reactive ion etching, and plasma activation equipment.
• Necessitates cross-team standardization of cleaning, bonding, and fluid handling procedures to ensure device reliability.
• Involves adaptation considerations when extending to different substrate materials or channel geometries beyond lithium niobate.
• Limited by the need for ultrapure fluids and particulate-free environments to prevent nanochannel clogging during operation.
