The fabrication of electrically addressable, high-aspect-ratio (> 1000:1) metal nanowires separated by gaps of single nanometers using either sacrificial layers of aluminum and silver or self-assembled monolayers as templates is described. These nanogap structures are fabricated without a clean room or any photo- or electron-beam lithographic processes by a form of edge lithography known as nanoskiving.

To investigate simple fabrication approaches for multiple assay needs, we created a fluid-absorbing channel system made of cotton material. This device was used to establish a multiple detection platform, and solve contamination issues that commonly affect lateral flow-based biomedical devices, for clinical urinalysis of nitrite, total protein, and urobilinogen.

FAQs
Finger spacing sets the spatial period of the electrode pattern, while the substrate’s material properties influence how rapidly the mechanical wave travels. Together, these factors determine the frequency at which the interdigitated structure most effectively launches or receives a surface acoustic wave. Fabrication therefore requires precise control of electrode geometry to achieve the intended operating response.
An alternating electrical voltage creates mechanical strain in the piezoelectric substrate through the inverse piezoelectric effect. The patterned fingers concentrate this electrically driven interaction into a repeating geometry that launches a surface acoustic wave. The reverse process allows mechanical waves to generate electrical signals, enabling the same device structure to function in signal generation and detection.
Electrode geometry, finger spacing, material selection, and alignment directly affect how efficiently the device couples electrical signals to mechanical waves. Small patterning or alignment differences can change the resulting frequency response and wave behavior. Careful control of these variables is especially important when fabricating compact filters, resonators, sensors, or acoustofluidic components that depend on predictable operation.
A microscale patterning process defines interlocking metal fingers on a piezoelectric substrate. Photolithography is one approach for transferring the intended electrode geometry, although another microscale patterning method may also be used. The resulting pattern must preserve the designed spacing, alignment, and finger arrangement because these features determine the device’s interaction with electrical signals and surface acoustic waves.
The essential platform combines a piezoelectric substrate with patterned metal electrodes arranged as interlocking fingers. The substrate provides the electromechanical response, while the metal pattern establishes the spatial structure needed for wave coupling. Selecting and controlling these elements supports the desired device behavior, particularly when the fabricated component must operate at a specific frequency or serve a specialized sensing function.
Researchers choose this approach when they need compact components that couple electrical signals and mechanical waves. Fabricated devices can serve as radio-frequency filters and resonators, or support chemical and biological sensing. They also provide a platform for acoustofluidic systems, where surface acoustic wave devices contribute to lab-on-a-chip technologies and related measurement architectures.
In sensing applications, the devices provide a patterned platform for chemical or biological measurement, while in acoustofluidic systems they support lab-on-a-chip technologies. Their usefulness comes from combining controlled electrode geometry with surface acoustic wave generation and detection. The fabrication quality therefore affects whether the resulting component delivers the compact, predictable behavior required for measurement or fluid-related device designs.
