Patent ID: 7632919

Claim:
A peptide reagent having a general structure selected from the group consisting of: PS m -(PSBP-BA p ) n ; a) PS m -(PSBP-AD) n ; b) PS m -(PSBP-TBD) n ; c) PS m -(PSBP-L-BA) n ; and d) PS m -[(PSBP) q -L(x)-(PSBP) r ] n -L-BA; e) wherein: i) PS is a polystyrene moiety non-covalently bound to PSBP; ii) PSBP is a PS binding peptide selected from the group consisting of SEQ ID NOs: 1-3; iii) BA is at least one benefit agent covalently or non-covalently bound to PBSP, wherein the at least one benefit agent is selected from the group consisting of pharmaceuticals, markers, colorants, conditioners and fragrances; iv) AD is at least one active domain incorporated into a PS binding peptide, wherein the at least one active domain comprises an antimicrobial functionality; v) TBD is at least one target binding domain incorporated into a PS binding peptide wherein the at least one target binding domain has an affinity selected from the group consisting of affinity for pigments, affinity for benefit agents, and affinity for print media; vi) L is a linker molecule; vii) m is the number of PS moieties available for binding; viii) n is less than or equal to m; ix) p=1-20; x) x=1-20; and xi) r=1-50.
