Membraneand

Membraneand is a neologism used in theoretical discussions of membrane science to denote the coupled system formed by a biological or synthetic membrane and its immediate environment. The term combines 'membrane' with a suffix indicating a domain or landscape, reflecting the idea that membranes do not exist in isolation but interact continuously with surrounding lipids, solvents, proteins, and applied fields.

Definition and scope: Membraneand encompasses the structural, mechanical, electrostatic, and transport properties that arise from membrane–environment coupling. Investigations focus on how membrane composition, curvature, phase state, and asymmetry influence permeability, signaling, and remodeling, and how external factors such as pH, ionic strength, temperature, and nanoscale inclusions alter these properties.

Methods and modeling: Researchers study membraneand using experiments such as fluorescence microscopy, cryo-EM, and spectroscopy, complemented by computational approaches including molecular dynamics, coarse-grained simulations, and continuum models. Multiscale frameworks aim to connect molecular interactions with emergent phenomena at the cellular or device level.

Applications and relevance: The concept informs design principles in drug delivery, biosensing, and membrane-based separations, where the surrounding milieu and interfacial phenomena substantially affect performance. In synthetic biology, membraneand concepts support constructing artificial cells and responsive materials.

Notes: Membraneand is not a standard term in all literature and remains primarily descriptive in niche or speculative contexts. Its usage varies across disciplines, and some researchers prefer to discuss membrane–environment coupling under more established headings such as membrane dynamics or interfacial science.
