Patent ID: 8912136

Claim:
A composition comprising a surface molecule selected from the group consisting of an iron oxide nanoworm, an iron oxide nanoparticle, an albumin nanoparticle, a liposome, a microparticle, and a fluorocarbon microbubble and at least one clot-binding compound, wherein the clot-binding compound comprises an amino acid sequence selected from the group consisting of C(NMe)REKA (SEQ ID NO:8), CR(NMe)EKA (SEQ ID NO:9), CR(CMe)EKA (SEQ ID NO:10), CRE(NMe)KA (SEQ ID NO:11), CRE(CMe)KA (SEQ ID NO:12), and CR(NMe)E(NMe)KA (SEQ ID NO: 13) and selectively binds to clotted plasma protein, wherein the composition causes clotting and amplifies the accumulation of the composition in tumors, wherein the clot-binding compound enhances the clotting in tumors compared to its unmodified derivative.
