Abstract

Soft micropillar arrays enable detailed studies of cellular mechanotransduction and biomechanics using traditional beam-bending models. However, they often rely on simplified assumptions, leading to significant errors in force estimation. We present MechanoBioCAD (MBC), a finite element method (FEM)-based tool designed specifically for micropillar research and error estimation. Unlike traditional methods, MBC leverages the principle of minimizing total potential energy, avoiding errors associated with beam bending assumptions. MBC automates FEM model generation, analysis, and post-processing, providing accurate force quantification based on deflection input. The tool addresses critical issues such as substrate deformation, interpillar interactions, improper load application heights, and nonlinear effects. Applied to fibroblast cell traction and Caenorhabditis elegans (C. elegans) thrashing cases, MBC recorded 23% and 34% errors in the estimated forces, respectively, compared to traditional methods. As an open-access tool with the Abaqus Student Edition, MBC democratizes rational design, analysis, and error estimation for researchers who are not subject matter experts in FEM.

MechanoBioCAD:用于机械生物学研究的通用半自动计算工具。
软微柱阵列可以使用传统的光束弯曲模型详细研究细胞力学转导和生物力学。然而,它们往往依赖于简化的假设,导致在力估计中出现重大误差。我们提出了MechanoBioCAD (MBC),这是一种基于有限元法(FEM)的工具,专门用于微柱研究和误差估计。与传统方法不同,MBC利用了最小化总势能的原理,避免了与波束弯曲假设相关的误差。MBC自动化FEM模型生成、分析和后处理,提供基于挠度输入的准确力量化。该工具解决了关键问题,如基板变形、柱间相互作用、负载应用高度不当和非线性效应。将MBC应用于成纤维细胞牵引和秀丽隐杆线虫(C. elegans)鞭打病例,与传统方法相比,估计力的误差分别为23%和34%。作为Abaqus学生版的开放访问工具,MBC为非FEM主题专家的研究人员实现了理性设计、分析和误差估计的民主化。

期刊介绍: Lab on a Chip is the premiere journal that publishes cutting-edge research in the field of miniaturization. By their very nature, microfluidic/nanofluidic/miniaturized systems are at the intersection of disciplines, spanning fundamental research to high-end application, which is reflected by the broad readership of the journal. Lab on a Chip publishes two types of papers on original research: full-length research papers and communications. Papers should demonstrate innovations, which can come from technical advancements or applications addressing pressing needs in globally important areas. The journal also publishes Comments, Reviews, and Perspectives.
