Abstract:
Carrier nanoparticles comprising a polymer containing a polyol coupled to a polymer containing a boronic acid and a linkage cleavable under reducing conditions, configured to present the polymer containing a boronic acid to an environment external to the nanoparticle and related compositions, methods and systems.

Claim (Index 1):
A nanoparticle comprising a polymer containing a polyol and a polymer containing a boronic acid, the polymer containing the boronic acid having proximal and distal ends, the proximal end comprising the boronic acid and the distal end comprising a functional group, wherein the polymer containing the boronic acid is conjugated to the polymer containing the polyol with a reversible borate ester linkage, and wherein the nanoparticle is configured to present the polymer containing the boronic acid to an environment external to the nanoparticle,\n wherein the polymer containing a polyol comprises one or more of at least one of the following structural units of Formula (I), (II), or (III): wherein:\n A comprises a polyol having 4 or 6 adjacent hydroxyl groups; and \n B comprises a neutral, cationic, or anionic organic moiety having a chemical backbone comprising \u2014C m H 2 m\u2014 linkages, where M\u22651, and one or more:\n (a) polyglycol linkage, \u2014(CH 2 \u2014CH 2 \u2014O) p \u2014, in the chemical backbone, where p is from 20-200; and/or \n (b) amidinium, quaternary ammonium, or imidazolium functional group in the chemical backbone; and/or \n (c) sulfonate, nitrate, carboxylate, phosphonate, or primary or secondary amine bonded to the chemical backbone; and \n wherein A and B are covalently linked by amide or ester linkages.
