Core–Shell Microgels at Air/Water Interfaces: Role of Interfacial Tension in Monolayer Evolution

Langmuir, Год журнала: 2025, Номер unknown

Core–shell microgels with rigid cores and soft, deformable hydrogel shells can assemble at air–water interfaces, forming freely floating monolayers. The strong adsorption such interfaces is related to the reduction in interfacial tension, which also causes deform laterally. degree of this deformation typically controlled through applied surface pressure. Until now, surprisingly little has been known about impact tension imbalances between areas covered a microgel monolayer microgel-free surroundings. In work, we systematically study evolution air/water dependence by addition sodium dodecyl sulfate or linear poly-N-isopropylacrylamide homopolymer free area. We do globally monitoring area Macroscopic changes are local microstructure studied atomic force microscopy (AFM). Depending on imbalance, either expands, shrinks, maintains its conformation. kinetics expansion compared for core–shell same silica core varying cross-linker densities.

We report the deposition of DNA nanostructures on self-assembled monolayers (SAMs), focusing stability both hydrophilic and hydrophobic SAMs. Our study reveals distinct outcomes based nature maintain structural integrity SAMs, whereas they experience deformation most Interestingly, is also sensitive to postdeposition washing procedures. The observations shed light intricate interplay between wettability SAMs nanostructures. An empirical trend emerged where increased hydrophobicity associated with a more severe This hypothesized arise from disrupted hydrogen bonding within exacerbated by interfacial tension during drying process. highlights potential role π-π stacking interactions bases in stabilizing work expands type substrates that can be used for applications nanotechnology need comprehensive understanding different surfaces.
