Self-assembled ordered silk fibroin nanofibrils after six-day maturation with silk sericin

Caption

Atomic force microscopy (AFM) image showing regenerated silk fibroin (RSF) and silk sericin (RSS) co-assemblies after six days of incubation followed by methanol treatment. The image reveals highly ordered, parallel-aligned nanofibrils, demonstrating that sericin-mediated compartmental confinement guides fibroin proteins into anisotropic, oriented nanostructures rather than random aggregates.
