The present invention provides amphiphilic telodendrimers that aggregate to form nanocarriers characterized by a hydrophobic core and a hydrophilic exterior. The nanocarrier core may include amphiphilic functionality such as cholic acid or cholic acid derivatives, and the exterior may include branched or linear poly(ethylene glycol) segments. Nanocarrier cargo such as hydrophobic drugs and other materials may be sequester in the core via non-covalent means or may be covalently bound to the telodendrimer building blocks. Telodendrimer structure may be tailored to alter loading properties, interactions with materials such as biological membranes, and other characteristics.

Reversibly crosslinked micelle systems

The present invention provides a nanoparticle including at least one poly(vinyl alcohol) (PVA) having a molecular weight of from about 10 kDa to about 200 kDa, substituted with one or more moieties selected from: a therapeutic agent having a boronic acid moiety, wherein the therapeutic agent is covalently linked to the PVA via a boronate ester bond; a crosslinking group having a disulfide moiety, wherein the crosslinking group is covalently linked to the PVA, and a porphyrin, wherein the porphyrin is covalently linked to the PVA. Use of the nanoparticles for tumor detection and the treatment of diseases, including methods for photodynamic therapy and photothermal therapy, are also described.
