Efficient one-pot synthesis and loading of self-assembled amphiphilic chitosan nanoparticles for low-leaching wood preservation

Self-assembled nanoparticles of acetylated cashew gum: Characterization and evaluation as potential drug carrier

“…Progressively increasing interest has been focused on selfassembled nanoparticles obtained from hydrophobized watersoluble polymers due to their potential biomedical and pharmaceutical applications (Ding, Richter, Matuana, & Heiden., 2011;Gonç alves & Gama, 2008;Jeong et al, 2006;Na, Lee, & Bae, 2003;Tan et al, 2011;Zhang et al, 2009). Hydrophobized or hydrophobic polymers can self-assemble in aqueous solution forming nanoparticles.…”

“…Hydrophobized or hydrophobic polymers can self-assemble in aqueous solution forming nanoparticles. In this context, amphiphilic block copolymers and hydrophobized polymers have been previously synthesized and their structure-function relationships studied (Ding et al, 2011;Lee et al, 2012;Na et al, 2003;Suksiriworapong, Sripha, & Heinze, 2008;Lucero, Claro, Casas, & Jimenez-Castellanos, 2013), dextran (Hassani et al, 2012;Aumelas, Serrero, Durand, Dellacherie, & Leonard, 2007;Hornig, Bunjes, & Heinze, 2009;Nichifor, Lopes, Carpov, & Melo, 1999), pullulan (Lee et al, 2012;Zhang et al, 2009), chondroitin sulfate (Park et al, 2010), chitosan (Hassani et al, 2012;Hwang, Kim, Kwon, & Kim, 2008), hyaluronic acid (Surace et al, 2009), amylose (Lalush, Bar, Zakaria, Eichler, & Shimoni, 2005), heparin (Park et al, 2004) and curdlan (Na, Park, Kim, & Bae, 2000), amylopectin (Lu, Zhang, Wang, & Chen, 2011) alginate (Shi, Zhang, Qi, & Cao, 2012;Pawar & Edgar, 2012) have been used for the formation of self-assembling nanoparticles with a view to their application as drug carriers.…”

Distribution of Silica-Coated Silver/Gold Nanostars in Soft- and Hardwood Applying SERS-Based Imaging

“…We also found elevated NP concentrations in the vicinity of bordered pits as shown for micronized copper by Matsunaga et al 11 However, micronized copper particles were found to accumulate mostly in the bordered pits, likely due to the bigger size and the more irregular shape of the particles. In another study, Ding et al 58 impregnated tebuconazole-loaded chitosan nanocapsules and showed their impregnation in a southern pine sapwood sample. Using slightly smaller particles with a very controlled and narrow size distribution, we could confirm their impregnation in the radial and tangential directions even with wood samples where the cross sections were covered.…”

Peptide-Directed Self-Assembly of Functionalized Polymeric Nanoparticles. Part II: Effects of Nanoparticle Composition on Assembly Behavior and Multiple Drug Loading Ability

“…Increasing the block length of the PMMA core increased the nanoparticle size. The advantage of using a PMMA core is that it is easily copolymerized with many monomers, so that if a faster drug release from the core is desired incremental amounts of a hydrophilic comonomer (e.g., HEMA) could be included in the hydrophobic core block to incrementally increase the release of a drug from the core domain . The hydrophobic block forms the center block, while PVP or PHEMA were used as the hydrophilic end chains that form the hydrophilic shell.…”
