The Dawning Era of Anticancer Nanomedicines: From First Principles to Application of Silk Nanoparticles

Advanced Therapeutics, Volume 8, Issue 1, January 2025.
This review evaluates the achievements and limitations of the anticancer silk nanomedicine field. Silk fibroin and silk‐inspired proteins are introduced as carrier materials by exploring recent advances to silk nanomedicine properties. The potential of bottom–up processing for silk nanoparticle production at a clinical scale is then explored.
