Abstract

This study aimed to calculate the effect of nanopatterns’ peak sharpness, width, and spacing parameters on P. aeruginosa and S. aureus cell walls by artificial neural network and finite element analysis. Elastic and creep deformation models of bacteria were developed in silico. Maximum deformation, maximum stress, and maximum strain values of the cell walls were calculated. According to the results, while the spacing of the nanopatterns is constant, it was determined that when their peaks were sharpened and their width decreased, maximum deformation, maximum stress, and maximum strain affecting the cell walls of both bacteria increased. When sharpness and width of the nano-patterns are kept constant and the spacing is increased, maximum deformation, maximum stress, and maximum strain in P. aeruginosa cell walls increase, but a decrease in S. aureus was observed. This study proves that changes in the geometric structures of nanopatterned surfaces can show different effects on different bacteria.

应用人工神经网络研究生物启发纳米图案表面的机械杀菌效果。
本研究旨在通过人工神经网络和有限元分析计算纳米图案的峰值锐度、宽度和间距参数对铜绿假单胞菌和金黄色葡萄球菌细胞壁的影响。在硅学中建立了细菌的弹性和蠕变变形模型。计算了细胞壁的最大变形、最大应力和最大应变值。结果表明,在纳米图案间距不变的情况下,当其峰值变尖、宽度变小时,两种细菌细胞壁的最大变形、最大应力和最大应变都会增加。当纳米图案的尖锐度和宽度保持不变且间距增大时,铜绿假单胞菌细胞壁的最大变形、最大应力和最大应变都会增加,但金黄色葡萄球菌的最大变形、最大应力和最大应变都会减少。这项研究证明,纳米图案表面几何结构的变化会对不同细菌产生不同的影响。

期刊介绍: The journal publishes papers in the field of biophysics, which is defined as the study of biological phenomena by using physical methods and concepts. Original papers, reviews and Biophysics letters are published. The primary goal of this journal is to advance the understanding of biological structure and function by application of the principles of physical science, and by presenting the work in a biophysical context. Papers employing a distinctively biophysical approach at all levels of biological organisation will be considered, as will both experimental and theoretical studies. The criteria for acceptance are scientific content, originality and relevance to biological systems of current interest and importance. Principal areas of interest include: - Structure and dynamics of biological macromolecules - Membrane biophysics and ion channels - Cell biophysics and organisation - Macromolecular assemblies - Biophysical methods and instrumentation - Advanced microscopics - System dynamics.
