## Description

- description: Nanomechanical sensors and their arrays have been attracting significant
    attention for detecting, discriminating and identifying target analytes. The sensing
    responses can be partially explained by the physical properties of the receptor
    layers coated on the sensing elements. Analytical solutions of nanomechanical
    sensing are available for a simple cantilever model including the physical parameters
    of both a cantilever and a receptor layer. These analytical solutions generally
    rely on the simple structures, such that the sensing element and the receptor
    layer are fully attached at their boundary. However, an actual interface in a
    real system is not always fully attached because of inhomogeneous coatings with
    low affinity to the sensor surface or partial detachments caused by the exposure
    to some analytes, especially with high concentration. Here, we study the effects
    of such macroscopic interfacial structures, including partial attachments/detachments,
    for static nanomechanical sensing, focusing on a Membrane-type Surface stress
    Sensor (MSS), through finite element analysis (FEA). We simulate various macroscopic
    interfacial structures by changing the sizes, numbers and positions of the attachments
    as well as the elastic properties of receptor layers (e.g., Young’s modulus and
    Poisson’s ratio) and evaluate the effects on the sensitivity. It is found that
    specific interfacial structures lead to efficient sensing responses, providing
    a guideline for designing the coating films as well as optimizing the interfacial
    structures for higher sensitivity including surface modification of the substrate.
