Figure 21.1 Block copolymer-nanoparticle co-assemblies as a function of nanoparticle size. The left shows nanoparticles smaller than the root-mean-square end-to-end distance of the block copolymer leading to particle distribution throughout the domain. The right scenario shows much larger nanopaiticles segregating out from the block copolymer.11 (Reprinted with permission from A. Jain and U. Wiesner, Macromolecules 2004, 37, 5665-5670.

Thermosensitive block copolymer nanoparticles containing doxorubicin increased cytotoxicity against Lewis lung carcinoma cells when activated by heating above the LCST [139], Chitosan was chemically conjugated to NIPAAm/vinyl laurate copolymer to enhance gene transfection in mouse myoblast cells [140]. Upon i.v. administration, poly(NIPAAm) nanoparticles are taken up by the reticuloendothelial cells of the liver and mild inflammatory and fibrotic responses are observed... [Pg.547]

The first nanoparticulate delivery system studied was Piloplex, consisting of pilocarpine ionically bound to poly(methyl)methacrylate-acrylic acid copolymer nanoparticles [44], Klein et al. [1,98] found that a twice-daily application of Piloplex in glaucoma patients was just as effective as three to six instillations of conventional pilocarpine eye drops. However, the formulation was never accepted for commercialization due to various formulation-related problems, including the nonbiodegradability, local toxicity, and difficulty of preparing a sterile formulation [208],... [Pg.746]

The signiflcant recent advances in both colloidal and polymer chemistries have enabled the successful fabrication of complex, defect-free tianoslruclures following a bottom-up approach [353]. Two recent related examples are mentioned to stress the point. Recently, triblock copolymer with divalent counter-ions in mixed solvents led to the formation of particles with tunable internal structure mimicking lipid anphiphiles for potential use in drug delivery. The mechanism of formation involves either nanophase separation within the triblock copolymer nanoparticle upon addition of water or microemulsion formation similar to that in lipid systems... [Pg.47]

For the formation of solid copolymer nanoparticles without a liquid core, PS-h-PMMA was used as a model system. In order to be able to form nanoparticles, the block copolymer was dissolved in chloroform and the solution was miniemulsified in water by adding the SDS. In this case, homogeneous droplets were formed. After evaporation of the chloroform, nanoparticles consisting entirely of block copolymer... [Pg.177]
