Abstract
Aptamers face challenges for use outside the ideal conditions in which they are developed. These difficulties are most palpable in vivo due to nuclease activities, rapid clearance, and off-target binding. Herein, we demonstrate that a polyphosphodiester-backboned molecular brush can suppress enzymatic digestion, reduce non-specific cell uptake, enable long blood circulation, and rescue the bioactivity of a conjugated aptamer in vivo. The backbone along with the aptamer is assembled via solid-phase synthesis, followed by installation of poly(ethylene glycol) (PEG) side chains using a two-step process with near-quantitative efficiency. The synthesis allows for precise control over polymer size and architecture. Consisting entirely of building blocks that are generally recognized as safe for therapeutics, this novel molecular brush is expected to provide a highly translatable route for aptamer-based therapeutics.

Abstract
Molecular polymer bottlebrushes are densely grafted, individual macromolecules with nanoscale proportions. The last decade has seen an increased focus on this material class, especially in nanomedicine and for biomedical applications. This Feature Article provides an overview of major developments in this area to highlight the many opportunities that these polymer architectures bring to nano-bio research. The article covers aspects of bottlebrush synthesis and summarises their use in drug and gene delivery, imaging, as theranostics and as prototype materials to correlate nanoparticle structure and composition to biological function and behaviour. Areas for future research in this area are discussed.

Abstract
Despite potency against a variety of cancers in preclinical systems, melittin (MEL), a major peptide in bee venom, exhibits non-specific toxicity, severe hemolytic activity, and poor pharmacological properties. Therefore, its advancement in the clinical translation system has been limited to early-stage trials. Herein, we report a biohybrid involving a bottlebrush-architectured poly(ethylene glycol) (PEG) and MEL. Termed pacMEL, the conjugate consists of a high-density PEG arrangement, which provides MEL with steric inhibition against protein access, while the high molecular weight of pacMEL substantially enhances plasma pharmacokinetics with a ∼10-fold increase in the area under the curve (AUC∞) compared to free MEL. pacMEL also significantly reduces hepatic damage and unwanted innate immune response and all but eliminated hemolytic activities of MEL. Importantly, pacMEL passively accumulates at subcutaneously inoculated tumor sites and exhibits stronger tumor-suppressive activity than molecular MEL. Collectively, pacMEL makes MEL a safer and more appealing drug candidate.

Abstract
Herein, we report the photoinitiated polymerization-induced self-assembly (photo-PISA) of spherical micelles consisting of proapoptotic peptide-polymer amphiphiles. The one-pot synthetic approach yielded micellar nanoparticles at high concentrations and at scale (150 mg mL-1 ) with tunable peptide loadings up to 48 wt. %. The size of the micellar nanoparticles was tuned by varying the lengths of hydrophobic and hydrophilic building blocks. Critically, the peptide-functionalized nanoparticles imbued the proapoptotic "KLA" peptides (amino acid sequence: KLAKLAKKLAKLAK) with two key properties otherwise not inherent to the sequence: 1) proteolytic resistance compared to the oligopeptide alone; 2) significantly enhanced cell uptake by multivalent display of KLA peptide brushes. The result was demonstrated improved apoptosis efficiency in HeLa cells. These results highlight the potential of photo-PISA in the large-scale synthesis of functional, proteolytically resistant peptide-polymer conjugates for intracellular delivery.

Abstract
The conjugation of hydrophilic polymers to proteins is an effective approach to prolonging their circulation time in the bloodstream and, hence, improving their delivery to the target region of interest. In this work, we report the synthesis of protein-polymer conjugates using a highly water-soluble sulfoxide-containing polymer, poly(2-(methylsulfinyl)ethyl acrylate) (PMSEA), through a combination of "grafting-to" and "grafting-from" methods. Oligomeric MSEA was synthesized by conventional reversible addition-fragmentation chain transfer (RAFT) polymerization and subsequently conjugated to lysozyme to produce a macromolecular chain transfer agent. This was followed by a visible light-mediated chain extension polymerization of MSEA to obtain a lysozyme-PMSEA conjugate (Lyz-PMSEA). It was found that the Lyz-PMSEA conjugate exhibited much reduced macrophage cellular uptake compared with unmodified and PEGylated lysozyme. Moreover, the Lyz-PMSEA conjugate was able to circulate longer in the bloodstream, demonstrating significantly improved pharmacokinetics demanded for pharmaceutical applications.

Abstract
Nonhepatic delivery of small interfering RNAs (siRNAs) remains a challenge for development of RNA interference-based therapeutics. We report a noncationic vector wherein linear poly(ethylene glycol) (PEG), a polymer generally considered as inert and safe biologically but ineffective as a vector, is transformed into a bottlebrush architecture. This topology provides covalently embedded siRNA with augmented nuclease stability and cellular uptake. Consisting almost entirely of PEG and siRNA, the conjugates exhibit a ~25-fold increase in blood elimination half-life and a ~19-fold increase in the area under the curve compared with unmodified siRNA. The improved pharmacokinetics results in greater tumor uptake and diminished liver capture. Despite the structural simplicity these conjugates efficiently knock down target genes in vivo without apparent toxic and immunogenic reactions. Given the benign biological nature of PEG and its widespread precedence in biopharmaceuticals, we anticipate the brush polymer-based technology to have a significant impact on siRNA therapeutics.

Abstract
Photoresponsive materials are emerging as ideal carriers for precisely controlled drug delivery owing to their high spatiotemporal selectivity. However, drawbacks such as slow release kinetics, inherent toxicity, and lack of targeting ability hinder their translation into clinical use. We constructed a new DNA aptamer-grafted photoresponsive hyperbranched polymer, which can self-assemble into nanoparticles, thereby achieving biocompatibility and target specificity, as well as light-controllable release behavior. Upon UV-irradiation, rapid release induced by disassembly was observed for Nile Red-loaded nanoparticles. Further in vitro cell studies confirmed this delivery system's specific binding and internalization performance arising from the DNA aptamer corona. The DOX-loaded nanoassembly exhibited selective phototriggered cytotoxicity towards cancer cells, indicating its promising therapeutic effect as a smart drug delivery system.

Abstract
PEGylation, the attachment of poly(ethylene glycol) (PEG), has been adopted to improve the pharmacokinetic properties of oligonucleotide therapeutics for nearly 30 years. Prior efforts mainly focused on the investigation of linear or slightly branched PEG having different molecular weights, terminal functional groups, and possible oligonucleotide sites for functionalization. Recent studies on highly branched PEG (including brush, star, and micellar structures) indicate superior properties in several areas including cellular uptake, gene regulation efficacy, reduction of side effects, and biodistribution. This review focuses on comparing the effects of PEG architecture on the physiochemical and biological properties of the PEGylated oligonucleotide.

Abstract
PEGylation of an oligonucleotide using a brush polymer can improve its biopharmaceutical characteristics, including enzymatic stability and biodistribution. Herein, we quantitatively explore the nuclease accessibility of the nucleic acid as a function of "depth" toward the backbone of the brush polymer. It is found that protein accessibility decreases as the nucleotide is located closer to the backbone. Thus, by moving the conjugation point from the terminus of the nucleic acid strand to an internal position, much smaller brushes can be used to achieve the same level of steric shielding. This finding also makes it possible to assess antisense gene regulation efficiency of these brush-DNA conjugates as a function of their nuclease stability.
