Summary: In recent years, there has been a growing interest in cell growth on patterned surfaces within tissue engineering. This study focused on preparing patterned scaffolds using Titanium (Ti) and polyvinyl chloride (PVC) and investigating their suitability for cell growth. The results showed that cell proliferation was observed on both patterned surfaces, with a higher proliferation rate on Ti-covered samples. Furthermore, it was found that the length of alkane groups in alkanethiols affected cell adhesion, with undecanethiol showing the highest level of cell proliferation. Scanning electron microscopy and optical microscopy analysis demonstrated significant cell proliferation on all prepared samples.

Summary: Soft matter displays various intrinsic physico-chemical attributes, and their mechanical properties significantly impact their performance. Biomechanics investigates the rigidity of these systems under exerted load forces, which affects cellular transduction processes in health and disease. Atomic force microscopy (AFM) and optical tweezers (OT) can determine the biomechanical parameters of these systems at the single-molecule level, making them valuable tools for characterizing mechanical forces in soft matter. This review highlights the capabilities of AFM and OT compared to classical bulk techniques and presents recent examples of nanomechanical measurements in various soft matter systems.

Summary: This study evaluates the limitations of measuring elastic moduli of Mo and MoTa thin films on Si substrates using nanoindentation and numerical modeling. The 10% rule for hardness measurements is confirmed, but smaller indentation depths are necessary for accurate elastic modulus measurement. Recommended testing protocol for thin film elastic modulus assessment using nanoindentation is provided.

Summary: This study systematically investigates the mechanical properties of Ag nanodisks fabricated by interference laser lithography (ILL) under 3D confinement effects. The results indicate that substrate effects have a significant influence on the mechanical response of the nanodisks, while lateral confinement effects become more pronounced at lower indentation depths. The confinement effects depend more on the relative size effects rather than the absolute length scales.

Summary: The current trend in miniaturized diagnostics shows a growing demand for mobile devices for health monitoring and point-of-care diagnostics, requiring rapid and environmentally friendly microfabrication techniques. Dry film photoresists (DFPs) are considered a promising solution for low-cost and greener microfabrication, able to partly or fully replace conventional silicon technologies. This study demonstrates the potential applications of DFPs in micro-analytical devices and showcases various scenarios for their utilization.

Summary: Many areas of modern materials chemistry require precise control over chemical environments at near-molecular scales. Most high-resolution interface patterning research has focused on hard surfaces, but design of interfaces for biological environments increasingly requires control over soft materials. This article describes a method for molecular-scale hard and soft interface design based on self-assembled molecular networks.
