Abstract
Small interfering RNA (siRNA) has significant potential to evolve into a new class of pharmaceutical inhibitors, but technologies that enable robust, tissue-specific intracellular delivery must be developed before effective clinical translation can be achieved. A pH-responsive, smart polymeric nanoparticle (SPN) with matrix metalloproteinase (MMP)-7-dependent proximity-activated targeting (PAT) is described here. The PAT-SPN was designed to trigger cellular uptake and cytosolic delivery of siRNA once activated by MMP-7, an enzyme whose overexpression is a hallmark of cancer initiation and progression. The PAT-SPN is composed of a corona-forming PEG block, an MMP-7-cleavable peptide, a cationic siRNA-condensing block, and a pH-responsive, endosomolytic terpolymer block that drives self-assembly and forms the PAT-SPN core. With this novel design, the PEG corona shields cellular interactions until it is cleaved in MMP-7-rich environments, shifting SPNζ-potential from +5.8 to +14.4 mV and triggering a 2.5 fold increase in carrier internalization. The PAT-SPN exhibited pH-dependent membrane disruptive behavior that enabled siRNA escape from endo-lysosomal pathways. Efficient intracellular siRNA delivery and knockdown of the model enzyme luciferase in R221A-Luc mammary tumor cellssignificantly depended on MMP-7 pre-activation. These combined data indicate that the PAT-SPN provides a promising new platform for tissue-specific, proximity-activated siRNA delivery to MMP-rich pathological environments.

Abstract
Highly efficient polymer-antibody conjugations were demonstrated via a tetrafluorophenyl active ester. A well-defined diblock copolymer was synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization with a temperature-responsive block, poly(N-isopropylacrylamide), and a block of N,N-dimethylacrylamide and 2,3,5,6-tetrafluorophenyl acrylate active ester. The polymer was conjugated to anti-p24 IgG antibody with about 100% efficiency in as little as 2 h at room temperature in a pH 10.8 buffer. The temperature-responsiveness of the polymer was conferred to the polymer-antibody conjugates after conjugation. The conjugates bound p24 antigen specifically and with binding efficiency comparable to native antibodies. Thus, the active ester diblock copolymer can facilitate the synthesis of temperature-responsive bioconjugates, which may be promising reagents for immunoassays, bioseparations, and specimen-enrichment applications.

Abstract
A study was conducted to survey the tolerance of ring-opening metathesis polymerization (ROMP) with respect to amino acid (a.a) identity of pentapeptide-modified norbornene-based monomers. A library of norbornyl-pentapeptides were prepared with the general structure, norbornyl-GX2PLX5, where residue 'X' was changed at each of the two positions (2 or 5) alternately to consist of the natural amino acids F, A, V, R, S, K, N, T, M, Q, H, W, C, Y, E, Q, and D. Each peptide monomer, free of protecting groups, was mixed in turn under a standard set of polymerization conditions with the ROMP initiator (IMesH2)C5H5N)2(Cl)2Ru=CHPh. Two sets of polymerization reactions were performed, one with Monomer:Initiator (M:I) ratio of 20:1, and another with M:I of 200:1. For the nucleophilic amino acids cysteine and lysine, polymerization reactions were quantitatively compared to those of their protected analogues. Furthermore, we describe polymerization of macromonomers containing up to 30 a.a. to test for tolerance of ROMP to peptide molecular weight. These reactions were studied via SEC-MALS and NMR. Finally, with knowledge of sequence scope in hand, we prepared a set of enzyme-substrate containing brush polymers and studied them with respect to their bioactivity.

Abstract
Living systems are replete with complex, stimuli-responsive nanoscale materials and molecular self-assemblies. There is an ever increasing and intense interest within the chemical sciences to understand, mimic and interface with these biological systems utilizing synthetic and/or semi-synthetic tools. Our aim in this review is to give perspective on this emerging field of research by highlighting examples of polymeric nanoparticles and micelles that are prepared utilizing biopolymers together with synthetic polymers for the purpose of developing nanomaterials capable of interacting and responding to biologically relevant stimuli. It is expected that with the merging of evolved biological molecules with synthetic materials, will come the ability to prepare complex, functional devices. A variety of applications will become accessible including self-healing materials, self-replicating systems, biodiagnostic tools, drug targeting materials and autonomous, adaptive sensors. Most importantly, the success of this type of strategy will impact how biomolecules are stabilized and incorporated into synthetic devices and at the same time, will influence how synthetic materials are utilized within biomedical applications.

Abstract
Many recent developments in polymer chemistry have advanced the synthesis of materials in which synthetic polymers are immobilized to biological (macro)molecules to enhance the solubility, stability, activity, or therapeutic utility of the biological entity. In particular, the versatility and robust nature of controlled radical polymerization (CRP) has enabled access to a diverse family of new polymer bioconjugates. While nitroxide-mediated, atom transfer radical (ATRP), and reversible addition-fragmentation chain transfer (RAFT) polymerizations have all proven useful for the preparation of well-defined end-functional polymers capable of being efficiently conjugated to biological molecules, ATRP and RAFT have proven especially proficient for the synthesis of conjugates by direct polymerization of vinyl monomers from biological components functionalized to contain a group capable of initiating chain growth. This Viewpoint highlights several recent advances that have relied on grafting-from by CRP, with particular attention devoted to a recent report that seeks to facilitate the process of grafting-from proteins via ATRP under biologically relevant conditions.

Abstract
This paper provides a third update to the review of reversible deactivation radical polymerization (RDRP) achieved with thiocarbonylthio compounds (ZC(=S)SR) by a mechanism of reversible addition-fragmentation chain transfer (RAFT) that was published in June 2005 (Aust. J. Chem. 2005, 58, 379). The first update was published in November 2006 (Aust. J. Chem. 2006, 59, 669) and the second in December 2009 (Aust. J. Chem. 2009, 62, 1402). This review cites over 700 publications that appeared during the period mid 2009 to early 2012 covering various aspects of RAFT polymerization which include reagent synthesis and properties, kinetics and mechanism of polymerization, novel polymer syntheses, and a diverse range of applications. This period has witnessed further significant developments, particularly in the areas of novel RAFT agents, techniques for end-group transformation, the production of micro/nanoparticles and modified surfaces, and biopolymer conjugates both for therapeutic and diagnostic applications.
