ABSTRACT Atom Transfer Radical Polymerization (ATRP) is an effective technique for the design and preparation of multifunctional, nanostructured materials for a variety of applications in biology and medicine. ATRP enables precise control over macromolecular structure, order, and functionality, which are important considerations for emerging biomedical designs. This article reviews recent advances in the preparation of polymer-based nanomaterials using ATRP, including polymer bioconjugates, block copolymer-based drug delivery systems, cross-linked microgels/nanogels, diagnostic and imaging platforms, tissue engineering hydrogels, and degradable polymers. It is envisioned that precise engineering at the molecular level will translate to tailored macroscopic physical properties, thus enabling control of the key elements for realized biomedical applications.

    ABSTRACT: In the past few years, perylenediimide-cored (PDI-cored) dendrimers have been successfully prepared and applied in various fields. In this review, we focus on the structural design and synthesis strategies of PDI-cored dendrimers that involve convergent and divergent synthesis approaches. When building the outer shell of PDI-cored dendrimers, first hydrophobic and then hydrophilic macromolecules are introduced. The advantages of water-soluble PDI-cored dendrimers include strong red fluorescence, excellent photostability, low cytotoxicity, high quantum yield, and versatile surface modification. The biological application of water-soluble PDI-cored dendrimers is broad, including fluorescence live-cell imaging, fluorescent labelling, and gene delivery, owing to the rapid development of these materials in the past decade. The challenges and outlooks in this field will also be discussed.

    ABSTRACT: Glycopolymer-b-poly(ε-caprolactone) (GP-PCL) block copolymer micelles (‘glycomicelles’) with tailored lactose functionalities were developed and investigated for hepatoma-targeted doxorubicin (DOX) delivery. Amphiphilic GP-PCL copolymers were readily prepared with controlled lactobionic acid (LBA) functionalities of 20%, 40%, 80%, and 100% (denoted as GP20-PCL, GP40-PCL, GP80-PCL, and GP100-PCL, respectively) through post-polymerization modification of the poly(acryloyl cyclic carbonate)-b-poly(ε-caprolactone) (PAC-b-PCL, 11.6–6.4 kg mol−1) block copolymer with thiolated LBA (LBA-SH) and 2-(2-methoxyethoxy)ethanethiol ((EO)2-SH) via the Michael-type addition reaction. These self-assembled glycomicelles had mean hydrodynamic diameters ranging from 31.9 to 76.8 nm depending on LBA densities, and exhibited high DOX loading efficiencies of 83.0–89.2%. In vitro release studies showed that the DOX release rate depended on the pH and LBA content. Flow cytometric analyses revealed that asialoglycoprotein receptor (ASGP-R) over-expressed HepG2 liver cancer cells following 4 h treatment with DOX-loaded glycomicelles had a 6.6–17.1-fold higher DOX level, depending on LBA densities, as compared to those treated with the corresponding DOX-loaded non-glycomicelles (100% substitution with (EO)2-SH) under otherwise the same conditions. MTT assays demonstrated that DOX-loaded GP20-PCL, GP40-PCL, GP80-PCL and GP100-PCL micelles had much lower half maximal inhibitory concentration (IC50) values of 2.05, 0.75, 0.45 and 0.43 μg DOX equiv. mL−1, respectively, in HepG2 cells than DOX-loaded non-glycomicelles (IC50: 6.55 μg mL−1 DOX equiv. mL−1). Competitive inhibition experiments showed that after the incubation with DOX-loaded glycomicelles for 4 h, more efficient killing activity against free HepG2 cells (−LBA) was observed, as compared to that against LBA-blocked HepG2 cells (+LBA) after a subsequent 72 h incubation. Glycomicelles with tailored LBA functionalities, high drug loading capacity, and high uptake by ASGP-R positive cells are promising candidates for liver cancer chemotherapy.

    ABSTRACT: The development of efficacious carriers is an important long-standing challenge in gene therapy. In the past few decades, tremendous progress has been made toward non-viral vectors for gene delivery including cationic lipids and polymers. However, there continues to be a need for clinically translatable polymer-based delivery carriers because they offer tunable degradation profiles and functional groups, diverse structures/morphologies, and scalability in preparation. Herein, we developed a library of 144 degradable polymers with varying amine and hydrophobic content via a facile method that involves thiobutyrolactone aminolysis and consequent thiol-(meth)acrylate or acrylamide addition in one-pot. The polymer platform was evaluated for pDNA and siRNA delivery to HeLa cells in vitro. Hydrophobically modified 5S, 2E1, 6CY1, 5CY2, and 2M1 grafted HEMATL polymers are capable of delivering pDNA depending on the chemical composition and the size of the polyplexes. Hydrophobically modified 5S and 2B grafted HEMATL and 5S grafted ATL polymers exhibit capability for siRNA delivery that approaches the efficacy of commercially available transfection reagents. Due to tunable functionality and scalable preparation, this synthetic approach may have broad applicability in the design of delivery materials for gene therapy.
