“…[ 59 ] Tsukruk and coworkers have prepared Langmuir monolayers or multilayers through the selfassembly of amphiphilic HBPs at the air-water interface or on the substrates. [60][61][62][63] For the latter, a solvent evaporation-induced self-assembly method is used. Barner-Kowollik and coworkers prepared a hyperbranched multiarm copolymer of H 20 -star -PS, and got a honeycomb fi lm with the evaporation of the polymer carbon disulfi de solution on a cold substrate at 0 ° C. [ 64 ] The pores were close to 1.5 μ m in diameter and arranged in hexagonal closed packing.…”

Hyperbranched polymers (HBPs) are highly branched macromolecules with a three-dimensional dendritic architecture. Due to their unique topological structure and interesting physical/chemical properties, HBPs have attracted wide attention from both academia and industry. In this paper, the recent developments in HBP self-assembly and their biomedical applications have been comprehensively reviewed. Many delicate supramolecular structures from zero-dimension (0D) to three-dimension (3D), such as micelles, fibers, tubes, vesicles, membranes, large compound vesicles and physical gels, have been prepared through the solution or interfacial self-assembly of amphiphilic HBPs. In addition, these supramolecular structures have shown promising applications in the biomedical areas including drug delivery, protein purification/detection/delivery, gene transfection, antibacterial/antifouling materials and cytomimetic chemistry. Such developments promote the interdiscipline researches among surpramolecular chemistry, biomedical chemistry, nano-technology and functional materials.

A condensed overview discusses the existing grafting approaches and the surface behavior of various hyperbranched polymers. We focus on the recent strategies and corresponding characterization of the resulting surface morphologies and structures with a number of relevant recent results from the authors' own research and existing literature. Some results discussed here are important for prospective applications of hyperbranched polymers in biomedical fields, for resistive coatings, tough blends, and reinforced nanocomposites are briefly summarized as well. V C 2011 Wiley Periodicals, Inc. J Polym Sci Part B: Polym Phys 50: 83-100, 2012 KEYWORDS: adsorption; hyperbranched; LB films; structural characterization; surfaces INTRODUCTION This publication presents a condensed overview of the existing grafting approaches as applied to hyperbranched polymers and discusses the surface morphologies of these polymers and corresponding composites and coatings. We mostly focus on the recent strategies and corresponding characterization of the resulting surface morphologies and structures developed in the authors' group with some relevant examples from current literature. A number of relevant results are also included here especially in relation to recent developments related to novel synthetic approaches of hyperbranched molecules as well as emerging applications of hyperbranched polymers and coatings for biomedical purposes, as resistive coatings, tough blends, and reinforced nanocomposites. Some comprehensive recent reviews on highly branched polymers, which are focused mainly on synthetic aspects can be found in literature.

“…The ligand-exchange reaction was achieved through a phasetransfer reaction in accordance with previous reports. [51,52] Functionalized gold nanoparticles were chemically grafted to the azide groups by means of click chemistry. [53][54][55] The final product was washed vigorously by repeated centrifugation and redispersion in an excess of solvent until the supernatant was transparent.…”
