Abstract
Nucleic acids are information-rich and readily available biomolecules, which can be used to template the polymerization of synthetic macromolecules. Here, we highlight the control over the size, composition, and sequence one can nowadays obtain by using this methodology. We also highlight how templated processes exploiting dynamic covalent polymerization can, in return, result in therapeutic nucleic acids fabricating their own dynamic delivery vector - a biomimicking concept that can provide original solutions for gene therapies.

Abstract
The growing applications of therapeutic nucleic acids requires the concomitant development of vectors that are optimized to complex one type of nucleic acid, forming nanoparticles suitable for further trafficking and delivery. While fine-tuning a vector by molecular engineering to obtain a particular nanoscale organization at the nanoparticle level can be a challenging endeavor, we turned the situation around and instead screened the complexation preferences of dynamic constitutional frameworks toward different types of DNAs. Dynamic constitutional frameworks (DCF) are recently-identified vectors by our group that can be prepared in a versatile manner through dynamic covalent chemistry. Herein, we designed and synthesized 40 new DCFs that vary in hydrophilic/hydrophobic balance, number of cationic headgroups. The results of DNA complexation obtained through gel electrophoresis and fluorescent displacement assays reveal binding preferences of different DCFs toward different DNAs. The formation of compact spherical architectures with an optimal diameter of 100-200 nm suggests that condensation into nanoparticles is more effective for longer PEG chains and PEI groups that induce a better binding performance in the presence of DNA targets.

Abstract
The use of nucleic acids as templates, which can trigger the self-assembly of their own vectors represent an emerging, simple and versatile, approach toward the self-fabrication of tailored nucleic acids delivery vectors. However, the structure-activity relationships governing this complex templated self-assembly process that accompanies the complexation of nucleic acids remains poorly understood. Herein, the class of arginine-rich dynamic covalent polymers (DCPs) composed of different monomers varying the number and position of arginines were studied. The combinations that lead to nucleic acid complexation, in saline buffer, using different templates, from short siRNA to long DNA, are described. Finally, a successful peptidic DCP featuring six-arginine repeating unit that promote the safe and effective delivery of siRNA in live cancer cells was identified.

Abstract
We introduce a pH-sensitive amide bond, inspired by citraconic anhydride, for the reversible conjugation of polymers to the lysine residues of proteins and antibodies. The pH sensitivity arises from a conformation lock at the end of the polymer, which we introduce by means of a Diels-Alder reaction, that positions a carboxylic acid close to the amide after conjugation occurs. The amide is stable over weeks at pH 7.4 but sensitive to hydrolysis at pH 5.5 and below, returning the amine to its original state. The pH sensitivity can be tuned by positioning secondary amide groups nearby. We use this approach to PEGylate an antibody to human serum albumin at high dilution and demonstrate successful recovery of the activity after hydrolysis at pH 5.5. These results offer a convenient and traceless approach to protein and antibody functionalization.

Abstract
Dynamic covalent polymers (DCPs) offer opportunities as adaptive materials of particular interest for targeting, sensing and delivery of biological molecules. In this view, combining cationic units and fluorescent units along DCP chains is attractive for achieving optical probes for the recognition and delivery of nucleic acids. Here, we report on the design of acylhydrazone-based DCPs combining cationic arginine units with π-conjugated fluorescent moieties based on thiophene-ethynyl-fluorene cores. Two types of fluorescent building blocks bearing neutral or cationic side groups on the fluorene moiety are considered in order to assess the role of the number of cationic units on complexation with DNA. The (chir)optical properties of the building blocks, the DCPs, and their complexes with several types of DNA are explored, providing details on the formation of supramolecular complexes and on their stability in aqueous solutions. The DNA-templated formation of DCPs is demonstrated, which provides new perspectives on the assembly of fluorescent DCP based on the nucleic acid structure.

Abstract
Supramolecular polymers are self-assembled materials displaying adaptive and responsive "life-like" behaviour which are often made of aromatic compounds capable of engaging in π-π interactions to form larger assemblies. Major advances have been made recently in controlling their mode of self-assembly, from thermodynamically-controlled isodesmic to kinetically-controlled living polymerization. Dynamic covalent chemistry has been recently implemented to generate dynamic covalent polymers which can be seen as dynamic analogues of biomacromolecules. On the other hand, peptides are readily-available and structurally-rich building blocks that can lead to secondary structures or specific functions. In this context, the past decade has seen intense research activity in studying the behaviour of aromatic-peptide conjugates through supramolecular and/or dynamic covalent chemistries. Herein, we review those impressive key achievements showcasing how aromatic- and peptide-based self-assemblies can be combined using dynamic covalent and/or supramolecular chemistry, and what it brings in terms of the structure, self-assembly pathways, and function of supramolecular and dynamic covalent polymers.

Abstract
In this review we consider one important member of the metalloenzymes family, the carbonic anhydrase (CA), involved in the treatment of several common diseases. Different approaches have emerged to regulate the activity of CA, mostly acting on the inner catalytic active site or outer microenvironment of the enzyme, leading to inhibition or activation of CA. In recent years, gradually increased attention has focused on the adoption of constitutional dynamic chemistry (CDC) strategies for the screening and discovery of potent inhibitors or activators. The participation of reversible covalent bonds enabled the enzyme itself to select the optimal ligands obtained from diverse building blocks with comparatively higher degree of variety, resulting in the fittest recognition of enzyme ligands from complex dynamic systems. With the increasing implementation of CDC for enzyme targets, it shows great potential for drug discovery or CO2 capture applications.

Abstract
Bioresponsive nanoparticles (NPs) are of interest for anticancer nanomedicines, owing to the possibility to 'design in' selective modulation of drug release at target sites. Here we describe the double emulsion formulation of redox-responsive NPs based on modified polyethylene glycol (PEG)-co-poly(lactic-co-glycolic acid) (PLGA) block copolymers and oligo (β-aminoesters) (OBAE), both of which contained disulfide linkages, for the co-delivery of a cytotoxic small molecule drug and a nucleic acid. In particular, we focused our attention on docetaxel (DTX) and a siRNA against TUBB3, a gene that encodes for βIII-tubulin, in order to have a synergistic effect in the treatment of lung cancer. Spherical NPs of around 150 nm with negative zeta potential and high loading efficiencies of both drugs were obtained. Stability and release studies showed "on demand" drug release under reducing conditions. Unloaded NPs containing PEG-disulfide-PLGA and OBAE were well-tolerated by lung cancer cells, thus masking the intrinsic cytotoxicity of OBAE, while for intracellular siRNA delivery, redox responsive NPs demonstrated a higher cell internalization with a preferential cytoplasmic accumulation of siRNA, with a subsequent fast gene-silencing efficiency. The viability of cells treated with combined DTX/TUBB3-siRNA NPs significantly decreased as compared to NPs loaded only with DTX, thus showing an efficient combined anticancer effect, due to a substantial reduction of β-tubulin expression. Finally, in an in vivo feasibility study employing an orthotopic lung cancer model, NPs formulated with an anti-luciferase siRNA distributed throughout the lungs following oro-tracheal administration, and demonstrated effective gene knockdown and no apparent cytotoxicity. Taken together, these results show that the double emulsion formulated redox responsive PEG-PLGA and OBAE systems represent a promising new therapeutic approach for the local combined chemo- and gene-therapy of lung cancer.

Abstract
Dynamic covalent libraries enable exploring complex chemical systems from which bioactive assemblies can adaptively emerge through template effects. In this work, we studied dynamic covalent libraries made of complementary bifunctional cationic peptides, yielding a diversity of species from macrocycles to polymers. Although polymers are typically expressed only at high concentration, we found that siRNA acts as a template in the formation of dynamic covalent polymers at low concentration in a process guided by electrostatic binding. Using a glycosylated building block, we were able to show that this templated polymerization further translates into the multivalent presentation of carbohydrate ligands, which subsequently promotes cell uptake and even cell-selective siRNA delivery.

Abstract
White-light-emitting soft materials with self-healing properties show extensive applications in many fields. Herein, a novel self-healing hydrogel is successfully fabricated using oxidized dextran (Odex) and dithiodipropionate dihydrazide (TPH). Carbon dots (CDs), Riboflavin (Ri) and Rhodamine B (RhB) are incorporated into the gel matrix to produce white light emission through fluorescence resonance energy transfer (FRET) process, thus achieving excellent Commission Internationale de L'eclairage (CIE) coordinate value of (0.30, 0.33). The emission colors can be easily tuned via changing proportions of three emitters or the excitation wavelength. When the hydrogels are coated on an ultraviolet light-emitting diodes (UV LED), the hydrogel coating converts UV light to white light and repairs itself in 20 h while a hole is dug from it. Thanks to reversible exchanging reactions of acylhydrazone and disulfide bonds in hydrogel networks, the hydrogel coating exhibits perfect self-healing property in a wide range of pH (from 5 to 9 except for 7). The excellent emission and self-healing properties of hydrogels have great value in practical applications.

Abstract
The rapid development of supramolecular polymer chemistry and constitutional dynamic chemistry over the last decades has made tremendous impact on the emergence of dynamic covalent polymers. These materials are formed through reversible covalent bonds, endowing them with adaptive and responsive features that have resulted in high interest throughout the community. Owing to their intriguing properties, such as self-healing, shape-memory effects, recyclability, degradability, stimuli-responsiveness, etc., the materials have found multiple uses in a wide range of areas. Of special interest is their increasing use for biomedical applications, and many examples have been demonstrated in recent years. These materials have thus been used for the recognition and sensing of biologically active compounds, for the modulation of enzyme activity, for gene delivery, and as materials for cell culture, delivery, and wound-dressing. In this review, some of these endeavors are discussed, highlighting the many advantages and unique properties of dynamic covalent polymers for use in biology and biomedicine.

Abstract
Delivery remains a major obstacle restricting the potential action of small molecular drugs as well as novel biologics which cannot readily enter cells without the help of a vector. A successful active delivery process involves three steps: (a) tagging the drug with a vector, (b) effective trafficking of this [drug-vector] conjugate through biological barriers, and finally (c) controlled drug release. While covalent bond formation and/or supramolecular association is involved in the making of the [drug-vector] conjugate, the final step requires precisely a controlled dissociation in order to trigger drug release. Therefore, in pursuit of smart, effective, and nontoxic delivery systems, it has become widely recognized that control over dynamic self-assembly could unleash the efficacy of artificial vectors. In this Account, I discuss our endeavors, and those of colleagues, in the recent implementation of Dynamic Covalent Chemistry (DCvC) in delivery applications. DCvC exploits reversible covalent reactions to generate covalent systems that can self-fabricate, adapt, respond, and fall apart in a controlled fashion. A privileged set of reversible covalent reactions has emerged in the community working on delivery applications and is based on condensation reactions (imine, acylhydrazone, oxime), and disulfide and boronate ester formations. The latest developments making this chemistry particularly attractive for such a DCvC approach are discussed. The rational justifying the potential of DCvC in delivery is based on the principle that using such reversible covalent reactions afford transient [drug-vector] conjugates which form spontaneously and chemoselectively, then adapt and self-correct their structure during self-assembly and trafficking thanks to the dynamic nature of the reversible covalent bonds, and finally respond to physicochemical stimuli such as pH and redox changes, thereby enabling controlled dissociation and concomitant drug release. For these reasons, DCvC has recently emerged as a leverage tool with growing prospects for advancing toward smarter delivery systems. The implementation of DCvC can follow three approaches that are discussed herein: (1) dynamic covalent bioconjugates, involving the transient covalent conjugation with a vector, (2) dynamic covalent vectors, involving the controlled dynamic and adaptive assembly and disassembly of vectors that complex drugs through supramolecular association, and (3) dynamic covalent targeting, involving the transient chemoselective formation of covalent bonds with the constituents of cell membranes. While DCvC has already attracted interest in material sciences, the recent results described in this Account showcase the vast potential of DCvC in biological sciences, and in particular in delivery applications where self-fabricated, adaptive, and responsive devices are of utmost importance.
