Schematic diagram of the M13 bacteriophage-based autologous template process. a Schematic diagram (red and green arrows) of a bacteriophage structure covered with approximately 2700 \(\alpha\)-helix main capsule (pVIII) protein subunits with five-helix symmetry and a double-thread axis of rotation. The bacteriophage has a helix angle (\(\phi\)) of \(41^{\circ }\) and the periodic subunit spacing is 3.3 nm. The red circle represents the target receptor to recognize target molecules. b Schematic of the helical self-template assembly of bacteriophage particles controlled by competing interfacial forces in the meniscus where the liquid crystal phase transition occurs. Polarized light microscopy images show iridescent colours resulting from the formation of liquid crystal phases at the air–liquid–solid interface
