Abstract
Official abstract text for this publication.
A method is generally provided for attaching a polymer chain onto a surface of a nanoparticle, where the polymer chain comprises a cyclic arrangement of saccharides. The resulting grafted nanoparticle is also generally provided, along with its methods of use by exposing to a bacteria colony.
First claim
Opening claim text (preview).
What is claimed: 1 . A method, comprising: attaching a polymer chain onto a surface of a nanoparticle, wherein the polymer chain comprises a cyclic arrangement of saccharides. 2 . The method as in claim 1 , wherein the cyclic arrangement of saccharides is a cyclodextrin. 3 . The method as in claim 1 , wherein the cyclic arrangement of saccharides is a cyclodextrin derivative. 4 . The method as in claim 1 , wherein the cyclic arrangement of saccharides comprises α-cyclodextrin. 5 . The method as in claim 1 , wherein the cyclic arrangement of saccharides comprises β-cyclodextrin. 6 . The method as in claim 1 , wherein the cyclic arrangement of saccharides comprises γ-cyclodextrin. 7 . The method as in claim 1 , wherein the molecular weight of the surface attached polymer chain is from about 500 to about 200,000 g/mol. 8 . The method as in claim 1 , wherein the polymer chain is attached to the surface of the nanoparticle via an anchoring compound. 9 . The method as in claim 1 , wherein a second polymeric chain is also attached to the surface of the nanoparticle to form a bi-modal nanoparticle. 10 . A grafted nanoparticle, comprising: a nanoparticle defining a surface; and a polymer chain covalently bonded to the surface of the nanoparticle, wherein the polymer chain comprises a cyclic arrangement of saccharides. 11 . The grafted nanoparticle as in claim 10 , wherein the polymer chain is covalently bonded to the surface of the nanoparticle via an anchoring compound. 12 . The grafted nanoparticle as in claim 10 , wherein the cyclic arrangement of saccharides is a cyclodextrin. 13 . The grafted nanoparticle as in claim 10 , wherein the cyclic arrangement of saccharides is a cyclodextrin derivative. 14 . The grafted nanoparticle as in claim 10 , wherein the cyclic arrangement of saccharides comprises α-cyclodextrin. 15 . The grafted nanoparticle as claim 10 , wherein the cyclic arrangement of saccharides comprises β-cyclodextrin. 16 . The grafted nanoparticle as in claim 10 , wherein the cyclic arrangement of saccharides comprises γ-cyclodextrin. 17 . The grafted nanoparticle as in claim 10 , wherein the molecular weight of the surface attached polymer chain is from about 500 to about 200,000 g/mol. 18 . The grafted nanoparticle as in claim 10 , wherein the polymer chain is attached to the surface of the nanoparticle via an anchoring compound. 19 . The grafted nanoparticle as in claim 10 , wherein a second polymeric chain is also attached to the surface of the nanoparticle to form a bi-modal nanoparticle. 20 . A method of capturing signaling molecules, comprising: exposing a bacteria colony to the grafted nanoparticle of claim 10 .
