AI Networking Cookbook: Practical recipes for AI-assisted network automation and development
Acoustophoresis and dielectrophoresis are frequently used for microscale particle and cell manipulation but are often used as two separate modalities. This article presents dynamic, selective patterning of micro- and nanoparticles using a reconfigurable surface acoustic wave microfluidic platform that integrates both a...
Porous silicon (PSi) biosensors offer significant potential for point-of-care diagnostics, yet their analytical performance is constrained by slow analyte diffusion into the porous matrix. To address this issue, we developed a lab-on-a-chip (LOC) device that combines a PSi immunosensor with a surface acoustic wave (SAW...
Surface acoustic wave (SAW) sensors, owing to their high operating frequencies, compatibility with planar micro-fabrication, and exceptional sensitivity to surface perturbations, are widely used in lab -on-a-chip and biomedical diagnostic applications. However, conventional SAW sensors operating in liquid environments...
Label-free separation of multiple micrometer and submicrometer particle populations from complex samples is a critical but elusive capability. We report an integrated acousto-dielectric chip in which the piezoelectric potential associated with tilted-angle standing surface acoustic waves changes the local electric fiel...
This work presents the design, fabrication, and validation of a surface acoustic wave (SAW) sensor utilizing ladder-type interdigital transducers (LIDTs) and direct group delay measurements. By exploiting the LIDT multi-subchannel structure, sensing and reference channels are integrated into a single device, significan...
Piezoelectric surface acoustic wave devices can drive charge carriers in semiconductors through the acoustoelectric effect, generating direct currents with potential applications in sensing and biomedicine. However, current sources based on this mechanism that combine nanoampere-level precision, a wide dynamic range,...
