Nanodiscs are small, disc-shaped structures designed to mimic biological cell membranes, composed of a lipid bilayer stabilized by scaffold proteins. Membrane proteins play crucial roles in essential processes such as nutrient and waste transport, molecular recognition, and cell signalling, making them…

Synthetic cells, also known as artificial cells or protocells, have wide ranging applications from drug delivery vectors to cell models. In biotechnology they can function as micro- or nanoreactors with possible applications in biocatalysis and photocatalysis. Phospholipids are by far the most commonly…
