unilamellære

Unilamellære refers to something composed of a single layer or membrane. The term is often used in biology and chemistry to describe structures that have a thickness equivalent to one molecule or one cell layer. For instance, in cell biology, a unilamellar vesicle is a liposome consisting of a single lipid bilayer enclosing an aqueous compartment. This is in contrast to multilamellar vesicles, which are composed of multiple concentric lipid bilayers.

In materials science and nanotechnology, unilamellar structures can refer to single layers of materials like graphene or certain types of coatings. The properties of unilamellar materials can differ significantly from their thicker counterparts due to their high surface area to volume ratio and quantum mechanical effects. Understanding the formation and characteristics of unilamellar structures is important for various applications, including drug delivery, biosensing, and the development of advanced materials. The precise control over the formation of single-layer structures is a key challenge and area of research.
