The above discussion clearly demonstrates the importance of surface roughness evaluation in modern science and engineering. Three-dimensional surface topography encompasses not only roughness (interpreted as short-wavelength irregularities) but also waviness (longer-wavelength surface deviations) and form at the meso-…

In the quality control of engineering surfaces, we aim to understand and maintain a good relationship between the manufacturing process and surface function. This is achieved by controlling the surface texture. The control process involves: 1) learning the functional parameters and their control values through…

Self-assembled monolayers (SAMs) have been widely utilized as a way of tailoring surface chemistry through the adsorption of organic molecules to different materials. SAMs are easy to prepare and offer a wide variety of organic molecules that afford additional or improved properties to the coated material. Spatial…

Surface topography guides cell behavior and is a tool to endow biomaterials with bioactive properties. The large number of possible designs makes it challenging to find the optimal surface structure to induce a specific cell response. The TopoChip platform is currently the largest collection of topographies with 2176…

A new model for FG nanobeams with engineering surfaces is developed. This engineering surface is considered as a different material phase with a surface texture (i.e. waviness and roughness). The initial curvatures of cantilever, simple supported, and clamped-clamped FG nanobeams due to surface residual stresses are…

Laser modification of polymer surfaces is critical in many contexts including self-cleaning materials, microelectronics, and biomedical research. Despite their utility, accessing these modified polymers requires expensive or complex materials and multi-step fabrication, masking, and washing processes. Here, we present…

The spacing between cells has a significant impact on cell-cell interactions, which are critical to the fate and function of both individual cells and multicellular organisms. However, accurately measuring the distance between cell membranes and the variations between different membranes has proven to be a challenging…

The effect of etching time on the statistical properties of the hydrophilic surface of SiO2/TiO2/Glass nano bi-layer has been studied using Atomic Force Microscopy (AFM) and stochastic approach based on the level crossing analysis. We have created a rough surface of the hydrophilic SiO2/TiO2 nano bi-layer system by…

Suboptimal biocompatibility of cardiovascular stents manifest as non-compliance at stent-artery interface in vivo. We optimized a plasma-activated coating (PAC) technology to modify cobalt chromium alloy L605 (PAC-L605) surface of an implantable coronary stent material, for improved biofunctionalization. The PAC-L605…

Extracellular vesicles (EVs) are promising drug delivery platforms that have been engineered to carry various drug modalities. Key strategies for generating those therapeutic EVs involve the direct fusion of protein of interest (POI) to EVs scaffold proteins with inherently high EVs-sorting ability. In this work, we…
