Summary: Polydimethylsiloxane (PDMS), a silicone elastomer, is widely used in health and biomedical fields due to its excellent optical and mechanical properties. However, its inherent hydrophobicity limits its applications, which can be overcome by hydrophilization through UV or plasma exposure. This study investigates the dynamics of hydrophobic recovery of PDMS and reveals the formation of a thin, stiff silica film on its surface after hydrophilization. The hydrophobic recovery process involves various nano-mechanical and diffusional processes, and the recovery is delayed and stalled in the vicinity of embedded hydrophilic beads.

Summary: Yad fimbriae are considered versatile bacterial adhesins that play a significant role in host or plant-pathogen recognition. This study used Single Molecule Force Spectroscopy to quantify the interaction forces between Yad fimbriae and self-assembled monolayers (SAM) on the nanoscale. Results showed strong adhesion of Yad fimbriae with xylose-functionalized probes, while interactions with other types of SAMs were non-specific.

Summary: In this study, the interactions between hydrocarbon oil and hydrophilic mineral surfaces were explored using CFM and MD simulations. Different functional groups were found to significantly influence the adhesion force between the oil collector and mineral surface, with polar hydrocarbon oils adhering strongly to the surface. The combination of MD and CFM provided a theoretical reference for mineral flotation separation.

Summary: In this study, a model of gecko keratin was developed to investigate the influence of electrostatic and van der Waals forces on gecko adhesion. The results showed that the pull-off force increased with increased water content and was inversely related to the water contact angle of the surface. The number and charge density of keratin and water at the surface were also found to play an important role in adhesion.

Summary: Atomic force microscopy was used to map the topography and qualitative mechanical characteristics of gallium-stabilized delta-phase plutonium coupons. The initial rough and heterogeneous surface of plutonium was observed, along with distinct striation patterns in qualitative nanomechanical mapping. Investigation suggested that the striations were not measurement artifacts or plutonium-specific features, and were influenced by mechanical working of the surface.

Summary: The dielectric permittivity and electric field profiles of interfacial water were probed and compared on hydrophobic and hydrophilic substrates. The results show that the interfacial air/water arrangement is similar to ice II and is induced by the interfacial electric field, suggesting a connection between ice crystal structures and liquid water properties.

Summary: This paper investigates the effect of silver and gold metal coating in various thicknesses on the adhesion force of silicon surfaces. It finds that coatings of both metals with different thicknesses can reduce the adhesion force, with gold being more effective than silver. Gold can be a better option to reduce adhesion force, especially in applications such as micro assembly.

Summary: This review examines the factors determining the strength of bacterial adhesion on titanium surfaces and its alloys. The study demonstrates that the hydrophilicity of surfaces influences bacterial adhesion, but hydrophobic bacteria can also adhere to hydrophilic surfaces through hydrogen bonding. Additionally, surface treatments that reduce areas favorable for bacterial adhesion have a greater impact on biofilm formation than surface roughness. Time-dependent studies are crucial for evaluating bacterial colonization as bacteria develop adaptation mechanisms over time.

Summary: Interfaces between minerals and water are crucial in various geochemical and industrial processes, with MgO serving as a valuable model system due to its simple cubic structure. Vibrational sum frequency generation (vSFG) spectroscopy and water contact angle (WCA) measurements on MgO single crystal surfaces reveal detailed molecular interactions between water molecules and hydroxylated MgO surfaces. Despite their hydrophilicity, MgO surfaces exhibit unique non-H-bonded OH stretching vibrations and interactions with water that are not fully captured by traditional WCA measurements.

Summary: The research showed that Acinetobacter sp. Tol 5 has strong adhesion force, mainly achieved through the interaction between the AtaA protein on the cell surface and the surface. This adhesion force increases with the increase of AtaA molecules. Amino acid hydrolysates and deionized water can inhibit the direct interaction between cells and surfaces, respectively.

Summary: Using atomic force microscopy, it was found that Na(V)1.5 is irregularly distributed on the surfaces of both normal and cancer breast cells, with higher expression on cancer cells. The stability of the Na(V)1.5-antibody complex is higher on normal breast cells compared to cancer breast cells. These findings provide insights into the interactions of ion channel-antibody systems and the role of sodium channels in tumor metastasis and invasion.
