Patent ID: 7700716

Claim:
A peptide reagent having a general structure selected from the group consisting of: a) PTFE m -(PTFEBP-BA p ) n ; b) PTFE m -(PTFEBP-AD) n ; c) PTFE m -(PTFEBP-TBD) n ; d) PTFE m -(PTFEBP-L-BA) n ; and e) PTFE m -[(PTFEBP) q -L (x) -(PTFEBP) r ] n -L-BA; wherein: i) PTFE is a polytetrafluoroethylene moiety non-covalently bound to PTFEBP; ii) PTFEBP is a PTFE binding peptide selected from the group consisting of SEQ ID NOs: 1-9; iii) BA is at least one benefit agent covalently or non-covalently bound to PTFEBP selected from the group consisting of pharmaceuticals, markers, colorants, conditioners and fragrances; iv) AD is at least one active domain incorporated into a PTFE binding peptide, wherein the AD has a functionality selected from the group consisting of a catalytic functionality and an antimicrobial functionality; v) TBD is at least one target binding domain incorporated into a PTFE binding peptide, wherein the TBD has an affinity selected from the group consisting of affinity for pigments, affinity for print media and affinity for body surfaces; vi) L is a liniker; vii) m=the number of PTFE moieties available for binding; viii) n is less than or equal to m; xi) p=1-20; x) x=1-20; and xi) r=1-50.
