The　development　of　materials　that　effectively　stop　bleeding　and　prevent　wound　adhesion　is　essential　in　both　military　and　medical　fields.　However,　traditional　hemostasis　methods,　such　as　cautery,　tourniquets,　and　gauze,　have　limitations.　In　recent　years,　new　nanomaterials　have　gained　popularity　in　medical　and　health　fields　due　to　their　unique　microstructural　advantages.　Compared　to　traditional　materials,　nanomaterials　offer　better　adhesion,　versatility,　and　improved　bioavailability　of　traditional　medicines.　Nanomaterials　also　possess　advantages　such　as　a　high　degree　and　stability,　self-degradation,　fewer　side　effects,　and　improved　wound　healing,　which　make　them　ideal　for　the　development　of　new　hemostatic　materials.　Our　review　provides　an　overview　of　the　currently　used　hemostatic　strategies　and　materials,　followed　by　a　review　of　the　cutting-edge　nanomaterials　for　hemostasis,　including　nanoparticles　and　nanocomposite　hydrogels.　The　paper　also　briefly　describes　the　challenges　faced　by　the　application　of　nanomaterials　for　hemostasis　and　the　prospects　for　their　future　development.
