Abstract
The frequent mutations of influenza A virus (IAV) have led to an urgent need for the development of innovative antiviral drugs. Glycopolymers offer significant advantages in biomedical applications owing to their biocompatibility and structural diversity. However, the primary challenge lies in the design and synthesis of well-defined glycopolymers to precisely control their biological functionalities. In this study, functional glycopolymers with sulfated fucose and 6'-sialyllactose were successfully synthesized through ring-opening metathesis polymerization and a postmodification strategy. The optimized heteropolymer exhibited simultaneous targeting of hemagglutinin and neuraminidase on the surface of IAV, as evidenced by MU-NANA assay and hemagglutination inhibition data. Antiviral experiments demonstrated that the glycopolymer displayed broad and efficient inhibitory activity against wild-type and mutant strains of H1N1 and H3N2 subtypes in vitro, thereby establishing its potential as a dual-targeted inhibitor for combating IAV resistance.

Abstract
The functional groups displayed on the surface of nanoparticles (NP) are known to play an important role in NP cellular uptake. However, only a few systematic studies have been reported to address their role, in large part because of the difficulty in regularly varying the number and structure of the functional groups on the NP surface. We employ a bottom-up strategy for the synthesis of water-soluble organic nanoparticles (ONPs) with different sizes and functional groups, using readily available monomers. Utilizing flow cytometry, we measured the HeLa cell uptake efficiency of ONPs that contain side-chains with a different (a) length, (b) number of hydroxyl groups, and (c) number of methyl groups. We have also investigated ONPs with the same functional groups but different sizes. The potential formation and influence of protein corona was examined using the same approach but in the presence of serum. The results demonstrate that under both serum and serum-free conditions the surface-exposed functional groups determine the efficiency of cellular uptake of the particles, and that the trend can be partially predicted by the lipophilicity of the polymeric ONP's repeating units. Also, by using a "masking" strategy, these particles' cellular uptake behavior could be altered conveniently.

Abstract
Virulence in Staphylococcus aureus is strongly and positively correlated with local cell density. Here we present an effective approach to modulate this group behaviour using multivalent peptide-polymer conjugates. Our results show that by attaching multiple AIP-4' units to macromolecular scaffolds, the agr QS response in S. aureus was affected strongly, while displaying a clear multivalency effect.

Abstract
Water-soluble triblock copolymers consisting of hydrophobic-hydrophilic-dye segments were synthesized by ring-opening metathesis polymerization (ROMP) of norbornadiene monomers, copper-catalyzed click reaction, osmium-catalyzed dihydroxylation, and the following transformations. These polymers in aqueous conditions could form spherical assemblies, whose diameters were 50-60 nm by TEM measurement. From in vivo optical imaging experiments, the spherical assemblies of these copolymers could be efficiently accumulated in tumor cells. In addition, the spherical assemblies of water-soluble polymers accumulated in a tumor cell over two weeks.

Abstract
In this Article, we describe a method for the polymerization of active esters based on N-hydroxysuccinimide 4-vinyl benzoate (NHS4VB) using surface initiated atom transfer radical polymerization (SI-ATRP). Poly(NHS4VB) brushes have high grafting density and a uniform and smooth morphology, and film thickness increases linearly with reaction time. Block copolymer brushes with 2-hydroxyethyl acrylate, tert-butyl acrylate, and styrene were synthesized from surface bound poly(NHS4VB) macroinitiators. The active ester brushes show rapid and quantitative conversion under aminolysis conditions with primary amines, which was studied using grazing incidence attenuated total reflection Fourier transform infrared (GATR-FTIR) and UV-vis spectroscopy. UV-vis was also used to quantify the amount of reactive groups in polymer brush layers of differing thickness. Functionalization of the active ester pendant groups with chromophores containing primary amines showed a linear correlation between the amount of chromophore incorporated into the brush layer and brush thickness. Grafting densities as high as 25.7 nmol/cm(2) were observed for a 50 nm brush. Block copolymer brushes with buried active ester functional moieties also undergo quantitative conversion with primary amines as confirmed by GATR-FTIR. We discuss the potential of activated ester brushes as universal scaffolds for sensor and microarray surfaces, where the twofold control of functionalizable active ester polymer and block copolymers provides well-ordered, tunable microenvironments.

Abstract
The applications of block copolymers are myriad, ranging from electronics to functionalized resins to therapeutics. The ring-opening metathesis polymerization (ROMP) is an especially valuable reaction for block copolymer assembly because each block can be generated with length control. We sought to use this polymerization to expand the repertoire of block copolymers by implementing a strategy that involves postpolymerization modification of a backbone bearing selectively reactive groups. To this end, we demonstrate that ROMP can be used to synthesize a block copolymer scaffold that possesses three types of functional groups-a succinimidyl ester, an alpha-chloroacetamide group, and a ketone-each of which can be modified independently. Thus, a single scaffold can be elaborated to afford a wide range of block copolymers. Exploiting this synthetic approach and the length control offered by ROMP, we assemble block copolymers capable of traversing the membrane and entering mammalian cells.

Abstract
We describe the synthesis of activated homopolymers and copolymers of controlled molecular weight based on the controlled radical polymerization of N-acryloyloxysuccinimide (NAS) by reversible addition fragmentation chain transfer (RAFT). We synthesized activated homopolymers in a range of molecular weights with polydispersities between 1 and 1.2. The attachment of an inhibitory peptide to the activated polymer backbone yielded a potent controlled molecular weight polyvalent inhibitor of anthrax toxin. To provide greater control over the placement of the peptides along the polymer backbone, we also used a semi-batch copolymerization method to synthesize copolymers of NAS and acrylamide (AAm). This approach enabled the synthesis of copolymers with control over the placement of peptide-reactive NAS monomers along an inert backbone; subsequent functionalization of NAS with peptide yielded well-defined polyvalent anthrax toxin inhibitors that differed in their potencies. These strategies for controlling molecular weight, ligand density, and ligand placement will be broadly applicable for designing potent polyvalent inhibitors for a variety of pathogens and toxins, and for elucidating structure-activity relationships in these systems.

Abstract
Shell crosslinked knedel-like (SCK) nanoparticles were prepared having thiol-terminated poly(ethylene glycol) (PEG) chains extending throughout their shell layers and were then conjugated with bovine serum albumin (BSA) as a model biomacromolecule. The SCKs originated from amphiphilic block copolymers of acrylic acid and styrene, PAA(66)-b-PS(71), pre-functionalized with ca. five mono-tBoc-protected diamino PEG(32) per polymer chain, which then had undergone deprotection and amidation with N-Succinimidyl-S-acetylthiohexanionate to introduce an acetyl-protected thiol chain terminus on the end of each PEG graft. Assembly of these amphiphilic graft block copolymers into micelles, by transitioning from N,N-dimethylformamide to water, was followed by amidation-based crosslinking throughout the shell layer, with the introduction of 2,2'-(ethylenedioxy)-bis(ethylamine) and 1-(3'-dimethylaminopropyl)-3-ethylcarbodiimide methiodide, to afford SCKs bearing the acetyl-protected thiol groups. Deprotection in aqueous buffer solution by reaction with hydroxylamine hydrochloride gave the SCKs presenting a nominal number of ca. 750 thiols per nanoparticle. The solution was assayed by Ellman's method resulting in a concentration of 55 ± 6 µM [HS], theoretical concentration 58 µM [HS], after which the coupling with BSA was performed immediately. Tetramethylrhodamine-labeled, maleimido-functionalized BSA was allowed to react with the thiol-functionalized SCKs at stoichiometries of ca. 10, 20 and 30 BSAs/SCK, after which UV-vis spectroscopy and Bradford's assay determined a coupling efficiency of >50-60%. The SCK particle diameters were measured by TEM to be 16 nm and 20 nm and their hydrodynamic diameters were measured by dynamic light scattering to be 20 nm and 30 nm, before and after BSA conjugation, respectively.

Abstract
This feature article provides a compilation of tools available for preparing well-defined peptide/protein-polymer conjugates, which are defined as hybrid constructs combining (i) a defined number of peptide/protein segments with uniform chain lengths and defined monomer sequences (primary structure) with (ii) a defined number of synthetic polymer chains. The first section describes methods for post-translational, or direct, introduction of chemoselective handles onto natural or synthetic peptides/proteins. Addressed topics include the residue- and/or site-specific modification of peptides/proteins at Arg, Asp, Cys, Gln, Glu, Gly, His, Lys, Met, Phe, Ser, Thr, Trp, Tyr and Val residues and methods for producing peptides/proteins containing non-canonical amino acids by peptide synthesis and protein engineering. In the second section, methods for introducing chemoselective groups onto the side-chain or chain-end of synthetic polymers produced by radical, anionic, cationic, metathesis and ring-opening polymerization are described. The final section discusses convergent and divergent strategies for covalently assembling polymers and peptides/proteins. An overview of the use of chemoselective reactions such as Heck, Sonogashira and Suzuki coupling, Diels-Alder cycloaddition, Click chemistry, Staudinger ligation, Michael's addition, reductive alkylation and oxime/hydrazone chemistry for the convergent synthesis of peptide/protein-polymer conjugates is given. Divergent approaches for preparing peptide/protein-polymer conjugates which are discussed include peptide synthesis from synthetic polymer supports, polymerization from peptide/protein macroinitiators or chain transfer agents and the polymerization of peptide side-chain monomers.
