Abstract
Polymers are widely studied materials with diverse properties and applications determined by molecular structures. It is essential to represent these structures clearly and explore the full space of achievable chemical designs. However, existing approaches cannot offer comprehensive design models for polymers because of their inherent scale and structural complexity. Here, a parametric, context-sensitive grammar designed specifically for polymers (PolyGrammar) is proposed. Using the symbolic hypergraph representation and 14 simple production rules, PolyGrammar can represent and generate all valid polyurethane structures. An algorithm is presented to translate any polyurethane structure from the popular Simplified Molecular-Input Line-entry System (SMILES) string format into the PolyGrammar representation. The representative power of PolyGrammar is tested by translating a dataset of over 600 polyurethane samples collected from the literature. Furthermore, it is shown that PolyGrammar can be easily extended to other copolymers and homopolymers. By offering a complete, explicit representation scheme and an explainable generative model with validity guarantees, PolyGrammar takes an essential step toward a more comprehensive and practical system for polymer discovery and exploration. As the first bridge between formal languages and chemistry, PolyGrammar also serves as a critical blueprint to inform the design of similar grammars for other chemistries, including organic and inorganic molecules.

Abstract
Polyurethanes (PUs) are a major family of polymers displaying a wide spectrum of physico-chemical, mechanical and structural properties for a large range of fields. They have shown suitable for biomedical applications and are used in this domain since decades. The current variety of biomass available has extended the diversity of starting materials for the elaboration of new biobased macromolecular architectures, allowing the development of biobased PUs with advanced properties such as controlled biotic and abiotic degradation. In this frame, new tunable biomedical devices have been successfully designed. PU structures with precise tissue biomimicking can be obtained and are adequate for adhesion, proliferation and differentiation of many cell's types. Moreover, new smart shape-memory PUs with adjustable shape-recovery properties have demonstrated promising results for biomedical applications such as wound healing. The fossil-based starting materials substitution for biomedical implants is slowly improving, nonetheless better renewable contents need to be achieved for most PUs to obtain biobased certifications. After a presentation of some PU generalities and an understanding of a biomaterial structure-biocompatibility relationship, recent developments of biobased PUs for non-implantable devices as well as short- and long-term implants are described in detail in this review and compared to more conventional PU structures.

Abstract
Hypoxia is a feature of solid tumors and it hinders the therapeutic efficacy of oxygen-dependent cancer treatment. Herein, we have developed all-organic oxygen-independent hybrid nanobullets ZPA@HA-ACVA-AZ for the "precise strike" of hypoxic tumors through the dual-targeting effects from surface-modified hyaluronic acid (HA) and hypoxia-dependent factor carbonic anhydrase IX (CA IX)-inhibitor acetazolamide (AZ). The core of nanobullets is the special zinc (II) phthalocyanine aggregates (ZPA) which could heat the tumor tissues upon 808-nm laser irradiation for photothermal therapy (PTT), along with the alkyl chain-functionalized thermally decomposable radical initiator ACVA-HDA on the side chain of HA for providing oxygen-independent alkyl radicals for ablating hypoxic cancer cells by thermodynamic therapy (TDT). The results provide important evidence that the combination of reverse hypoxia hallmarks CA IX as targets for inhibition by AZ and synergistic PTT/TDT possess incomparable therapeutic advantages over traditional (reactive oxygen species (ROS)-mediated) cancer treatment for suppressing the growth of both hypoxic tumors and their metastasis.

Abstract
Reconstitution of urethral defects through a tissue-engineered autologous urethra is an exciting area of clinical urology research. Despite rapid advances in this field, a tissue-engineered urethra is still inaccessible to clinical applications because of the poor vascularization of the current scaffold materials, especially for the reconstruction of complex urethral defects. In this study, we report the preparation of multifaceted bio-interfacing tissue-engineered autologous scaffolds based on alternating block polyurethane (abbreviated as PU-alt), a kind of tubular scaffold with a hierarchical nanofiber architecture, flexible mechanical properties and a hydrophilic PEGylation interface capable of promoting adhesion, oriented elongation, and proliferation of New Zealand rabbit autologous urethral epithelial cells (ECs) and smooth muscle cells (SMCs) simultaneously, and also upregulating the expression of keratin (AE1/AE3) in ECs and contractile protein (α-SMA) in SMCs as well as the subsequent synthesis of elastin. Three months in vivo scaffold substitution of rabbit urethras displayed that the engineered autologous PU-alt scaffold grafts, with a coating rich in seed cell-matrix, could induce local neo-vascularization, facilitating oriented SMC remodeling and lumen epithelialization as well as patency. Our findings indicate a central role of the synergistic interplay of seed cell-matrix bio-interface and nano-topographic cues in the vascularized urethral reconstruction.

Abstract
Nanomedicine, acting as the magic bullet, is capable of combining immunotherapy with other treatments to reverse a cold tumor (immune depletion) into a hot tumor. However, how to comprehensively inhibit the immunosuppressive tumor microenvironment (TME) remains a major challenge for immunotherapy to achieve the maximum benefits. Thus, a strategy that can simultaneously increase the recruitment of tumor infiltrating lymphocytes (TILs) and comprehensively reprogram the immunosuppressive TME is still urgently needed. Herein, a thermal-sensitive nitric oxide (NO) donor S-nitrosothiols (SNO)-pendant copolymer (poly(acrylamide-co-acrylonitrile-co-vinylimidazole)-SNO copolymer, PAAV-SNO) with upper critical solution temperature (UCST) was synthesized and employed to fabricate an erythrocyte membrane-camouflaged nanobullet for codelivery of NIR II photothermal agent IR1061 and indoleamine 2,3-dioxygenase 1 (IDO-1) inhibitor 1-methyl-tryptophan (1-MT). This multifunctional nanobullet possessed long circulation in vivo, enhanced accumulation at the tumor site, and therapeutics-controlled release by NIR II laser, thereby it could avoid unspecific drug leakage while enhancing biosecurity. More importantly, the immunogenic cell death (ICD) induced by local hyperthermia from photothermal therapy (PTT) could be conducive for the increased recruitment of CD8+ cytotoxic T lymphocytes (CTLs) at the tumor site. Furthermore, through interfering in the IDO-1 activity by 1-MT and normalizing the tumor vessels by in situ generated NO, the immunosuppressive TME was comprehensively reprogrammed toward an immunostimulatory phenotype, achieving the excellent therapeutic efficacy against both primary breast cancer and metastases. Collectively, this multifunctional nanobullet described in this study developed an effective and promising strategy to comprehensively reprogram suppressive TME and treat "immune cold" tumors.

Abstract
Combining chemo-therapeutics with immune checkpoint inhibitors facilitates killing cancer cells and activating the immune system through inhibiting immune escape. However, their treatment effects remain limited due to the compromised accumulation of both drugs and inhibitors in certain tumor tissues. Herein, a new poly (acrylamide-co-acrylonitrile-co-vinylimidazole-co-bis(2-methacryloyl) oxyethyl disulfide) (PAAVB) polymer-based intelligent platform with controllable upper critical solution temperature (UCST) was used for the simultaneous delivery of paclitaxel (PTX) and curcumin (CUR). Additionally, a hyaluronic acid (HA) layer was coated on the surface of PAAVB NPs to target the CD44-overexpressed tumor cells. The proposed nanomedicine demonstrated a gratifying accumulation in tumor tissue and uptake by cancer cells. Then, the acidic microenvironment and high level of glutathione (GSH) in cancer cells could spontaneously decrease the UCST of polymer, leading to the disassembly of the NPs and rapid drug release at body temperature without extra-stimuli. Significantly, the released PTX and CUR could induce the immunogenic cell death (ICD) to promote adaptive anti-tumor immunogenicity and inhibit immunosuppression through suppressing the activity of indoleamine 2,3-dioxygenase 1 (IDO1) enzyme respectively. Therefore, the synergism of this intelligent nanomedicine can suppress primary breast tumor growth and inhibit their lung metastasis. A new copolymer PAAVB was prepared with pH- and GSH- controllable upper critical solution temperature (UCST) properties. A nano-platform with PAAVB copolymer core and HA shell was developed and showed the capability to deliver PTX and CUR. The antitumor immune response was synergistically stimulated by PTX-induced ICD and CUR induced IDO1activity suppression. The synergism of intelligent nanomedicine could suppress the primary breast tumor growth and inhibit their lung metastasis.

Abstract
Black phosphorus quantum dots (BPQDs) with excellent biocompatibility, outstanding photothermal and photodynamic efficacies have attracted significant attention in cancer therapy. However, the low environmental stability and poor dispersity of BPQDs limit their practical applications. In the present work, biocompatible anionic waterborne polyurethane (WPU) nanoparticles were synthesized from castor oil to encapsulate the BPQDs. The WPU-BPQDs with a BPQDs loading capacity of about 13.8% (w/w) exhibited significantly improved dispersion and environmental stability without affecting the photothermal efficiency of BPQDs. Intriguingly, it was found that WPU encapsulation led to significant enhancement in the reactive oxygen species (ROS) generation of BPQDs, which indicated the enhanced photodynamic efficacy of the encapsulated BPQDs as compared to the bare BPQDs. The effect of solution pH on the ROS generation efficiency of BPQDs and the pH variation caused by BPQDs degradation was then investigated to explore the possible mechanism. In acidic solution, ROS generation was suppressed, while BPQDs degradation led to the acidification of the solution. Fortunately, after being encapsulated inside the WPU nanoparticles, the degradation rate of BPQDs became slower, while the acidic environment around BPQDs was favorably regulated by WPU nanoparticles having a special electrochemical double layer consisting of interior COO- and exterior NH(Et3)+, thus endowing the WPU-BPQDs-boosted production of ROS as compared to the bare BPQDs. Considering the undesired acidic tumor environment, this unique pH regulation effect of WPU-BPQDs would be beneficial for in vivo photodynamic efficacy. Both in vitro and in vivo experiments showed that WPU-BPQDs could effectively improve photodynamic therapy (PDT) and maintain outstanding photothermal therapy (PTT) effects. Together with the excellent dispersity, biocompatibility, and easy biodegradability, WPU-BPQDs can be a promising agent for PDT/PTT cancer treatments.

Abstract
The specific binding of fluorescent probes or biomolecules to the actin cytoskeleton network is increasingly important for monitoring various complex cellular activities such as cell adhesion, proliferation, locomotion, endocytosis, and cell division. However, improving cell uptake and subcellular resolution is still the main obstacle for successful and wide application of cellular fluorescent probes. Here, we designed and synthesized an amphiphilic block polyurethane with peculiar photophysical properties of aggregation induced emission (AIE), which can be used in living cell imaging to promote selective visualization of cell structures. The AIE effect polyurethane (abbreviated as AIE-PU) was prepared by two-step polymerization of diisocyanate terminated polyethylene glycol and polycaprolactone with hydroxyl terminated AIE dye. A series of characterization techniques proved the successful synthesis of AIE-PU. Due to the amphiphilic chain segment of its linear block molecule, AIE-PU block copolymers can self-assemble into spherical nanoparticles in aqueous solution, showing relatively stable photophysical properties and good water dispersion. Cellular experiments demonstrated that AIE-PUs have low toxicity and high actin network affinity. Moreover, the uptake mechanism was studied by low temperature and metabolic inhibition experiments, showing that AIE-PU nanoparticles could be easily internalized into different living cells through energy-dependent endocytosis, and can be transported from the cellular periphery to the actin network via clathrin- and caveolae-dependent transport pathway. Upon binding with the actin network, the inter-chain AIE mechanism of the probe was significantly enhanced, which is pivotal for the long-term stable fluorescence imaging of actin microfilament network in living cells. Finally, compared with commercial actin dyes, this probe showed higher photostability, even after a longer retention time, without significant fluorescence quenching.

Abstract
Herein we report the construction of a nanoparticle-based drug delivery system which targets a key regulator in tumour angiogenesis. We exploit a Variable New Antigen Receptor (VNAR) domain, conjugated using site-specific chemistry, to direct poly lactic acid-co-glycolic acid-polyethylene glycol (PLGA-PEG) nanoparticles to delta like canonical Notch ligand 4 (DLL4). The importance of site-specific chemistry is demonstrated.

Abstract
Theranostic approaches using nanotechnology have been a hot research area for the past decade. All nano drug delivery techniques and architectures have some limitations, as do diagnostic nano-approaches. Thus, combining nano drug delivery strategies with diagnostic techniques using nanoparticles for improving imaging modalities has been the key to fill up those gaps. In the past decade, lots of approaches have been made with different combinations of biomaterials fabricated/synthesized to nanostructures with modified surface functionalization to improve their overall theranostic properties. This article summarizes recent research works based on the biomaterials used for fabricating these nanostructures. Their combinations with other biomaterials have been demonstrated with their overall advantages and limitations.

Abstract
Oral chemotherapy has been emerging as a hopeful therapeutic regimen for the treatment of various cancers because of its high safety and convenience, lower costs, and high patient compliance. Currently, nanoparticulate drug delivery systems (NDDS) exhibit many unique advantages in mediating oral drug delivery; however, many anticancer drugs that were susceptible in hostile gastrointestinal (GI) environment showed poor permeability across intestinal epithelium, and most materials used as drug carriers are nonactive excipients and displayed no therapeutically relevant function, which leads to low oral bioavailability and therapeutic efficacy of anticancer drugs (e.g., paclitaxel). Inspired by these, in this study, paclitaxel (PTX) was used as a model drug, depending on intermolecular hydrogen-bonded interactions, PTX-loaded tannic acid/poly( N-vinylpyrrolidone) nanoparticles (PTX-NP) were produced by a flash nanoprecipitation (FNP) process. The optimized PTX-NP showed an average diameter of 54 nm with a drug encapsulation efficiency of 80% and loading capacity of 14.5%. Molecular dynamics simulations were carried out to illuminate the assembling mechanism of hydrogen-bonded PTX-NP. In vitro and in vivo results confirmed that PTX-NP showed pH-dependent intestinal site-specific drug release, P-gp inhibitory function by tannic acid (TA), prolonged intestinal retention, and improved trans-epithelial transport properties. Oral administration of PTX-NP generated a high oral delivery efficiency and relative oral bioavailability of 25.6% in rats, and further displayed a significant tumor-inhibition effect in a xenograft breast tumor model. These findings confirmed that our PTX-NP might be a promising oral drug formulation for chemotherapy.

Abstract
Eventhough it is well established that materials can promote stem cell differentiation, hard tissue formation is a templated process for which little is known regarding the in vitro process. We have found that surface curvature enables self-assembly of triple helical collagen fibrils into banded bundle structures from rat tail and human collagen secreted by dental pulp stem cells. Collagen fibrils were adsorbed at 4 °C on spun cast flat P4VP films and electrospun fibers. Protein adsorption was observed on both surfaces, but large banded bundles with a uniform spacing of approximately 55 nm were present only on the fiber surfaces. SEM/EDS mapping showed that dental pulp stem cells plated on the same surfaces biomineralized copiously only along the electrospun fibers. Raman spectroscopy indicated that despite the presence of adsorbed collagen on the flat surfaces, only the deposits present on the fibrous surface had a protein to hydroxyl apatite ratio similar to natural dentin from human teeth. RT-PCR indicated up regulation of collagen, osteocalcin and dental sialophosphate protein, confirming that odontogenic differentiation is promoted only on the fiber scaffolds. Taken together the results indicate that, in addition to surface chemistry, the supermolecular structure of ECM collagen, which is essential in directing DPSCs differentiation and templating biomineralization, can be modified by the underlying surface morphology. STATEMENT OF SIGNIFICANCE The past decade has been focused efforts in the use of dental pulp stem cells (DPSC) for dental regeneration. Eventhough the factors required for DPSCs differentiation have been well studied, actual mineral deposition, positively identified as dentin, has not been achieved in vitro. Hard tissue is known to be a templated process in vivo where the mineral to protein ratio is tightly controlled via proteins which aid in collagen conformation and mineral sequestration. Here we show that one can mimic this process in vitro via the combination of materials selection and morphology. The material chemistry is shown to induce genetic upregulation the genes responsible for collagen and osteocalcin, while Raman spectroscopy confirms the translation and adsorption the proteins on the substrate. But, we show that the simple presence of collagen is not enough to template actual biomineral deposition similar to that found in vivo. Mineral deposition is a complicated process templated on collagen bundles and mediated by specific sibling proteins that determine the protein to mineral ratio. Here we show that surface curvature can reduce the barrier to collagen bundle formation, directing DPSC differentiation along odontogenic lineage, and subsequently templating actual dentin, comparable to that found in vivo in human teeth.
