Therefore, it is necessary to develop a potential new method to detect lesions of cellular peripheral brush. Here, a piecewise linear viscoelastic constitutive model of cell is established considering the joint contribution of the peripheral brush and intra-cellular structure. By combining the Laplace transformation and its inverse transformation, and the differential method in the temporal domain and differential quadrature method (DQM) in the spatial domain, the signal interpretation models for quasi-static and dynamic signals of microcantilever are solved. The influence mechanisms of the peripheral brush on the viscoelastic properties of cells and quasi-static/dynamic signals of microcantilever are clarified. The results not only reveal that the peripheral brush has significant effects on the complex modulus of the cell and multi-channel signals of the microcantilever, but also suggest that an alternative mapping method by collecting multi-channel signals including quasistatic and higher frequency signals with more brush indexes could be potentially used to identify cancerous cells.  \nKeywords: peripheral brush; cellular viscoelasticity; microcantilever; detection mechanism; multi-channel signals  \n1. Introduction  \nThe cellular brush is one of the important peripheral microstructures in a living cell, which consist mainly of microvilli, microridges, and cilia [1], and plays an important role in physiological processes such as cell–cell interaction, cell migration, differentiation and proliferation, embryonic development, inflammation, and tumors [2,3] . Relevant experiments based on atomic force microscopy (AFM) have shown that the cellular peripheral brush can affect the mechanical responses of cells, thus changing the static/dynamic detection signals of AFM microscale sensors [4–6] . Thus, it is imperative to develop a reasonable constitutive model to accurately reflect the cellular peripheral brush and to take the mechanical properties of the peripheral brush as crucial indicators to distinguish between normal and cancerou","cbCaif1Cq1TpAaOu","https://ap.wps.com/l/cbCaif1Cq1TpAaOu","pdf",7060902,16,"English","# Abstract\n# Introduction\n## Cellular peripheral brush and AFM signals\n## Quasi-static and dynamic AFM detection modes\n## Need for viscoelastic constitutive modeling","[{\"question\":\"Why is detecting the cellular peripheral brush important?\",\"answer\":\"Disease development such as renal cysts, cancer, and viral infection is closely associated with pathological changes and defects in the cellular peripheral brush.
