Abstract
Aims: Stimuli-responsive polymersomes are promising tools for protein-based therapies, but require deeper understanding and optimization of their pathology-responsive behavior. Materials & methods: Hyaluronic acid (HA)-poly(b-lactic acid) (PLA) polymersomes self-assembled from block copolymers of varying molecular weights of HA were compared for their physical properties, degradation and intracellular behavior. Results: Major results showed increasing enzyme-responsivity associated with decreasing molecular weight. The major formulation differences were as follows: the HA(5 kDa)-PLA formulation exhibited the most pronounced release of encapsulated proteins, while the HA(7 kDa)-PLA formulation showed the most different release behavior from neutral. Conclusion: We have discovered design rules for HA-PLA polymersomes for protein delivery, with lower molecular weight leading to higher encapsulation efficiency, greater release and greater intracellular uptake.

Abstract
The development of new approaches for the treatment of the increasingly antibiotic-resistant pathogen Pseudomonas aeruginosa was targeted by enhancing the effect of local antimicrobial photodynamic therapy (aPDT) using poly(ethylene glycol)-block-poly(lactic acid) (PEG114-block-PLAx) nanocarriers that were loaded with a ruthenium-based photosensitizer (PS). The action of tris(1,10-phenanthroline) ruthenium (II) bis(hexafluorophosphate) (RuPhen3) encapsulated in PEG114-block-PLAx micelles and vesicles was shown to result in an appreciable aPDT inactivation efficiency against planktonic Pseudomonas aeruginosa. In particular, the encapsulation of the PS, its release, and the efficiency of singlet oxygen (1O2) generation upon irradiation with blue light were studied spectroscopically. The antimicrobial effect was analyzed with two strains of Pseudomonas aeruginosa. Compared with PS-loaded micelles, formulations of the PS-loaded vesicles showed 10 times enhanced activity with a strong photodynamic inactivation effect of at least a 4.7 log reduction against both a Pseudomonas aeruginosa lab strain and a clinical isolate collected from the lung of a cystic fibrosis (CF) patient. This work lays the foundation for the targeted eradication of Pseudomonas aeruginosa using aPDT in various medical application areas.

Abstract
The irregular expression or activity of enzymes in the human body leads to various pathological disorders and can therefore be used as an intrinsic trigger for more precise identification of disease foci and controlled release of diagnostics and therapeutics, leading to improved diagnostic accuracy, sensitivity, and therapeutic efficacy while reducing systemic toxicity. Advanced synthesis strategies enable the preparation of polymers with enzymatically activatable skeletons or side chains, while understanding enzymatically responsive mechanisms promotes rational incorporation of activatable units and predictions of the release profile of diagnostics and therapeutics, ultimately leading to promising applications in disease diagnosis and treatment with superior biocompatibility and efficiency. By overcoming the challenges, new opportunities will emerge to inspire researchers to develop more efficient, safer, and clinically reliable enzymatically activatable polymeric carriers as well as prodrugs.

Abstract
Polymer melt strength (MS) is strongly correlated with its molecular structure, while their relationship is not very clear yet. In this work, designable long-chain branched polylactide (LCB-PLA) is prepared in situ by using a tailor-made (methyl methacrylate)-co-(glycidyl methacrylate) copolymer (MG) with accurate number of reactive sites. A new concept of branching density (φ) in the LCB-PLA system is defined to quantitively study their relationship. Importantly, a critical point of φc = 5.5 mol/104 mol C is revealed for the first time, below which the zero-shear viscosity (η0 ) corresponding to MS increases slowly with a slope of Δη0 /Δφ = 1400, while it increases sharply above this critical point due to entanglement of neighboring LCB-PLA chains. Consequently, the MS of PLA increased by >100 times by optimizing the LCB structures while maintaining processibility. Therefore, this work provides a deeper understanding and feasible route in quantitative design of polymers with high(er) melt strength for some specialty applications.

Abstract
The fabrication, characterization and application of a nanoporous Silicon Rugate Filter (pSiRF) loaded with an enzymatically degradable polymer is reported as a bare eye detection optical sensor for enzymes of pathogenic bacteria, which is devoid of any dyes. The nanopores of pSiRF were filled with poly(lactic acid) (PLA), which, upon enzymatic degradation, resulted in a change in the effective refractive index of the pSiRF film, leading to a readily discernible color change of the sensor. The shifts in the characteristic fringe patterns before and after the enzymatic reaction were analyzed quantitatively by Reflectometric Interference Spectroscopy (RIfS) to estimate the apparent kinetics and its dependence on enzyme concentration. A clear color change from green to blue was observed by the bare eye after PLA degradation by proteinase K. Moreover, the color change was further confirmed in measurements in bacterial suspensions of the pathogen Pseudomonas aeruginosa (PAO1) as well as in situ in the corresponding bacterial supernatants. This study highlights the potential of the approach in point of care bacteria detection.

Abstract
The rapid and selective detection of bacterial contaminations and bacterial infections in a non-laboratory setting using advanced sensing materials holds the promise to enable robust point-of-care tests and rapid diagnostics for applications in the medical field as well as food safety. Among the various possible analytes, bacterial enzymes have been targeted successfully in various sensing formats. In this current work, we focus on the systematic investigation of the role of surface area on the sensitivity in micro- and nanostructured autonomously reporting sensing hydrogel materials for the detection of bacterial enzymes. The colorimetric sensing materials for the detection of β-glucuronidase (ß-GUS) from Escherichia coli (E. coli) were fabricated by template replication of crosslinked pullulan acetoacetate (PUAA) and by electrospinning chitosan/polyethylene oxide nanofibers (CS/PEO NFs), both equipped with the chromogenic substrate 5-bromo-4-chloro-3-indolyl-β-D-glucuronide. The investigation of the dependence of the initial reaction rates on surface area unveiled a linear relationship of rate and thereby time to observe a signal for a given concentration of bacterial enzyme. This knowledge was exploited in nanoscale sensing materials made of CS/PEO NFs with diameters of 295 ± 100 nm. Compared to bulk hydrogel slabs, the rate of hydrolysis was significantly enhanced in NFs when exposed to bacteria suspension cultures and thus ensuring a rapid detection of living E. coli that produces the enzyme β-GUS. The findings afford generalized design principles for the improvement of known and novel sensing materials towards rapid detection of bacteria by nanostructuring in medical and food related settings.

Abstract
In recent years, infectious diseases have again become a critical threat to global public health largely due to the challenges posed by antimicrobial resistance. Conventional antibiotics have played a crucial role in combating bacterial infections; however, their efficacy is significantly impaired by widespread drug resistance. Natural antimicrobial peptides (AMPs) and their polymeric mimics demonstrate great potential for killing bacteria with low propensity of resistance as they target the microbial membrane rather than a specific molecular target, but they are also toxic to the host eukaryotic cells. To minimize antibiotics systemic spread and the required dose that promote resistance and to advocate practical realization of the promising activity of AMPs and polymers, smart systems to target bacteria are highly sought after. This review presents bacterial recognition by various specific targeting molecules and the delivery systems of active components in supramolecules. Bacteria-induced activations of antimicrobial-based nanoformulations are also included. Recent advances in the bacteria targeting and delivery of synthetic antimicrobial agents may assist in developing new classes of highly selective antimicrobial systems which can improve bactericidal efficacy and greatly minimize the spread of bacterial resistance.

Abstract
In drug delivery, enzyme-responsive drug carriers are becoming increasingly relevant because of the growing association of disease pathology with enzyme overexpression. Polymersomes are of interest to such applications because of their tunable properties. While polymersomes open up a wide range of chemical and physical properties to explore, they also present a challenge in developing generalized rules for the synthesis of novel systems. Motivated by this issue, in this perspective, we summarize the existing knowledge on enzyme-responsive polymersomes and outline the main design choices. Then, we propose heuristics to guide the design of novel systems. Finally, we discuss the potential of an integrated approach using computer simulations and experimental studies to streamline this design process and close the existing knowledge gaps.

Abstract
Wound management is a major global issue, and there is a growing challenge to develop more effective hemostatic dressings to control bleeding and prevent pathogen infections. In this study, a multifunctional wound dressing was developed to meet the clinical need. The hemostatic layer of wound dressing can quickly stop the bleeding. Meanwhile, the detection layer is used for real-time fluorescence monitoring of the bacterial colonization. When infection occurs, wound dressing is further subjected to illumination for in-situ photodynamic antibacterial treatment. In the rabbit ear artery hemostasis model, the hemostasis time of the wound dressing was 1 s. The detection limit of the wound dressing was 1.4 × 105 CFU/cm2 for Escherichia coli, 5.9 × 105 CFU/cm2 for Staphylococcus aureus, and 3.8 × 106 CFU/cm2 for Pseudomonas aeruginosa, respectively. Compared with the control group, an enhanced wound closure (up to 97.3%) were observed in mice treated with the wound dressing. In vitro and in vivo experiment results suggested that the wound dressing was effective in killing pathogenic bacterial and exhibited good biological compatibility, and induced no inflammatory reaction. The proposed design prevents massive bleeding and wound infection, and further promotes wound healing. STATEMENT OF SIGNIFICANCE: In this work, we developed a multifunctional wound dressing, capable of rapid hemostasis, colorimetric monitoring of bacterial infection, and in situ photodynamic antibacterial. The hemostatic layer can quickly stop the bleeding due to its large specific surface area and adsorption pore size for platelet at bleeding site. Meanwhile, the detection layer can intelligently monitor the bacterial infection and respond to report bacterial infection by emitting fluorescence. When infection occurs, wound dressing can be used for in-situ photodynamic antibacterial treatment. In vitro and in vivo results showed that the wound dressing was biocompatible, prevented massive bleeding and wound infection, and further promoted wound healing.

Abstract
Controllable drug release is promising for fighting against antimicrobial resistance, which is a critical threat to human health worldwide. Herein, new hyaluronidase-responsive conjugated oligo(thiophene ethynylene) (OTE)-covalently modified hyaluronic acid (OTE-HA) nanoparticles for on-demand release of antimicrobial agents are reported. The synthesis of amphiphilic OTE-HA was carried out by esterification reaction. The resulting macromolecules were self-assembled in water to form nanoparticles, in which the hydrophobic OTE section, as bactericides, formed "cores" and the hydrophilic hyaluronic acid (HA) formed "shells". The OTE-HA nanoparticles avoid bactericide premature leakage and effectively block the dark cytotoxicity of the OTE section, possessing excellent biocompatibility. Using methicillin-resistant Staphylococcus aureus (MRSA) as an example, hyaluronidase, largely secreted by MRSA, can in situ trigger the release of OTE via hydrolyzing OTE-HA nanoparticles into fragments, even disaccharides linked with OTE. Importantly, the OTE section could effectively break cell membranes, leading to bacterial death. The half-maximal inhibitory concentration of the nanoparticles against MRSA is 3.3 μg/mL. The great antibacterial activity of OTE-HA nanoparticles against Gram-positive bacteria Streptococcus pneumoniae further confirms the controllable bactericide delivery mechanism. OTE-HA nanoparticles coated on a surface can also effectively inhibit the growth of bacteria, which holds a remarkable promise in biomedical applications. Therefore, this work provides a favorable strategy of on-demand and in situ drug release for sterilization and defeating antimicrobial resistance.

Abstract
Recent developments in the fabrication of core-shell polymer nanocapsules, as well as their current and future applications, are reported here. Special attention is paid to the newly introduced surfactant-free fabrication method of aqueous dispersions of nanocapsules with hydrophobic liquid cores stabilized by amphiphilic copolymers. Various approaches to the efficient stabilization of such vehicles, tailoring their cores and shells for the fabrication of multifunctional, navigable nanocarriers and/or nanoreactors useful in various fields, are discussed. The emphasis is placed on biomedical applications of polymer nanocapsules, including the delivery of poorly soluble active compounds and contrast agents, as well as their use as theranostic platforms. Other methods of fabrication of polymer-based nanocapsules are briefly presented and compared in the context of their biomedical applications.

Abstract
Natural organisms are made of different types of microcompartments, many of which are enclosed by cell membranes. For these organisms to display a proper function, the microcompartments must be selectively permeable. For example, cell membranes are typically permeable toward small, uncharged molecules such as water, selected nutrients, and cell signaling molecules, but impermeable toward many larger biomolecules. Here, it is reported for the first time dynamic compartments, namely surfactant-stabilized double emulsions, that display selective and tunable permeability. Selective permeability is imparted to double emulsions by stabilizing them with catechol-functionalized surfactants that transport molecules across the oil shell of double emulsions only if they electrostatically or hydrophobically attract encapsulants. These double emulsions are employed as semipermeable picoliter-sized vessels to controllably perform complexation reactions inside picoliter-sized aqueous cores. This thus far unmet level of control over the transport of reagents across oil phases opens up new possibilities to use double emulsion drops as dynamic and selectively permeable microcompartments to initiate and maintain chemical and biochemical reactions in picoliter-sized cell-mimetic compartments.

Abstract
There is a rapidly increasing interest in developing stimuli-responsive nanomaterials for treating a variety of diseases. By enabling the activation of function locally at the sites of interest, it is possible to increase therapeutic efficacy significantly while simultaneously reducing adverse side effects. While there are many sophisticated nanomaterials available, they are often highly complex and not easily transferrable to industrial scales and clinical settings. However, nanomaterials based on hyaluronic acid offer a compelling strategy for reducing their complexity while retaining several desirable benefits such as active targeting and stimuli-responsive degradation. Herein, the basic properties of hyaluronic acid, its binding partners, and natural routes for degradation by hyaluronidases-hyaluronic-acid-degrading enzymes-and oxidative stresses are discussed. Recent advances in designing hyaluronic acid-based, actively targeted, hyaluronidase- or reactive-oxygen-species-responsive nanomaterials for both diagnostic imaging and therapeutic delivery, which go beyond merely the classical targeting of CD44, are summarized.

Abstract
Tumor-targeted multifunctional nanocarriers play an important role in tumor diagnosis and treatment. Herein, disulfide bonds linked amphiphilic hyaluronan-SS-poly(ε-caprolactone) diblock copolymers (HA-SS-PCL) were synthesized and studied as theranostic nanocarriers for tumor diagnosis and treatment. The chemical structure of HA-SS-PCL was confirmed by Fourier transform infrared spectroscopy (FTIR) and proton nuclear magnetic resonance (1H NMR). The self-assembling behavior of the HA-SS-PCL into GSH-responsive micelles and their degradation were characterized by fluorescence spectroscopy, dynamic light scattering (DLS) and transmission electron microscopy (TEM). Theranostic nanocarriers encapsulating doxorubicin (DOX) and superparamagnetic iron oxide (SPIO) were formed via a dialysis. In vitro drug release results suggested that the HA-SS-PCL micelles possessed reductant-triggered doxorubicin release ability, which was confirmed by 100% of DOX release from HA-SS-PCL micelles within 12 h under 10 mM of glutathione (GSH), whereas about 40% of DOX was released under non-reductive condition within 24 h. Both flow cytometry and confocal laser scanning microscopy (CLSM) analysis revealed that the HA-SS-PCL micelles loaded with DOX were internalized in HepG2 cell via a receptor mediated mechanism between hyaluronan and the CD44 receptor. Furthermore, the MTT assay and cell apoptosis analysis revealed that the DOX-loaded HA-SS-PCL micelles exhibited pronounced antitumor ability towards HepG2 cells compared with that of the reduction-insensitive HA-PCL micelles at the same DOX dosage. The r2 relaxivity value of the DOX/SPIO loaded HA-SS-PCL micelles was up to 221.2 mM-1 s-1 (Fe). Thus, the obtained HA-SS-PCL block copolymers demonstrate promising potential as tumor targeting theranostic nanocarriers in the field of tumor diagnosis and treatment.

Abstract
This work reports on a new approach to rapidly and selectively detect and discriminate enzymes of pathogenic from those of nonpathogenic bacteria using a patterned autonomously reporting hydrogel on a transparent support, in which the selectivity has been encoded by the pattern shape to enable facile detection by a color change at one single wavelength. In particular, enzyme-responsive chitosan hydrogel layers that report the presence of the enzymes β-glucuronidase (β-Gus) and β-galactosidase (β-Gal), produced by the nonvirulent Escherichia coli K12 and the food-borne biosafety level 3 pathogen enterohemorrhagic E. coli, respectively, via the blue color of an indigo dye were patterned by two complementary strategies. The comparison of the functionalization of patterned chitosan patches on a solid support with two chromogenic substrates on one hand and the area-selective conjugation of the substrates on the other hand showed that the two characteristic enzymes could indeed be rapidly and selectively discriminated. The limits of detection of the highly stable sensing layers for an observation time of 60 min using a spectrophotometer correspond to enzyme concentrations of β-Gus and β-Gal of ≤5 and ≤3 nM, respectively, and to ≤62 and ≤33 nM for bare eye detection in nonoptimized sensor patches. These results confirm the applicability of this approach, which is compatible with the simple measurement of optical density at one single wavelength only as well as with parallel, multiplexed detection, to differentiate the enzymes secreted by a highly pathogenic E. coli from a nonpathogenic E. coli on the basis of specifically secreted enzymes. Hence, a general approach for the rapid and selective detection of enzymes of different bacterial species for potential applications in food safety as well as point-of-care microbiological diagnostics is described.

Abstract
Sinomenine is a natural alkaloid with important biological activities (e.g. anti-cancer, anti-inflammatory, and anti-allergic). However, the unstability and short half-life absolutely limited its application to foods. Microencapsulation technology can offer a way to solve these issues. In this study, polylactic acid microcapsules loading sinomenine hydrochloride were fabricated by phase inversion emulsification-drying in liquid technique. The results showed that microcapsules had nice spherical shape, uniform particle size, and free flowing. The encapsulation efficiency was 89.2% and drug loading was 8.9% under the optimal conditions. In vitro release assays demonstrated that release of sinomenine from microcapsules was sustained and slow. Moreover, it was found that the sinomenine release fitted Fickian diffusion mechanism. The results of cytotoxicity study showed that sinomenine-loaded microcapsules were biocompatible. Sinomenine-loaded microcapsules could inhibit the growth of MDA-MB-231 cells using methyl thiazolyl tetrazolium assay. In summary, polylactide microcapsules exhibit excellent properties for sinomenine that can be used in drug or food industry.

Abstract
Assays to analyze the degradation, lysis and leakage of vesicles are commonly utilized in biology and physical chemistry. Here we show the fluorescence lifetime-based sensing of the leakage of stimuli responsive PEG114-b-PLA167 block copolymer vesicles. The time-resolved technique differentiates between the fluorophore molecules in the solvated state at high concentrations, and in the wall material and in the solvated state at low concentrations. The vesicle leakage occurs after an incubation period, which was detected by the change of the time correlated single photon counting decays.

Abstract
Dual enzyme-responsive peptides were synthesized by masking the ɛ-amine of lysine with various enzyme substrates. Enzymatic cleavage of these sequences unmasked the ɛ-amine, allowing for further digestion by a second enzyme, which was monitored colorimetrically. This modular peptide design should provide substrates for a large combination of clinically relevant enzymes.

Abstract
Understanding the enrichment and intracellular trafficking of substances is centrally important to the biological systems. Here, employing an amphiphilic molecule (denoted by TPE-11) bearing tetraphenylethene moiety, known for aggregation induced emission property, we demonstrated its localization shifting in Hela cells after prolonged incubation. Through a set of delicately designed experiments, we found that one type of cytoskeleton, i.e., microtubule, is responsible for the intracellular transportation regardless of the sources of fluorogens, via endocytosis pathways or not. As the polymerization of microtubules was blocked, the TPE-11 fluorogens were hindered to move to the inner cytoplasm, but scattered in the cells. On the contrary, blocking the polymerization of microfilament has no such effect. We assume that the dynamic polymerization of microtubules should be responsible to the transportation of TPE-11. More importantly, we found that the interaction between TPE-11 and microtubule proteins also happens during process of polymerization in vitro. The intracellular trafficking of TPE-11 by microtubules may be generalized to other amphiphilic molecules as well as endocytosis pathway, and serves as references in designing functional molecules involved in the intracellular transportation.

Abstract
A novel multifunctional aggregation-induced emission (AIE) nanoaggregate for targeted imaging and enzyme-triggered chemotherapy was successfully fabricated via a one-step assembly. In this system, a quaternary ammonium-modified tetraphenylethene derivative (QA-TPE) acted as the AIE fluorophore as well as the chemotherapeutic agent, and a water-soluble acidic polysaccharide, hyaluronic acid (HA) acted as the aggregation-inducing scaffold, AIE turn-on agent, and targeting agent for CD44 receptor-mediated cancer cells. More importantly, HA endowed the QA-TPE/HA nanoaggregate both good biocompatibility and hysteretic chemotherapy activity, which were achieved by controlling the release of QA-TPE using the endogenous HAase in CD44 receptor-mediated cancer cells.

Abstract
Polymersomes are robust vesicles made from amphiphilic block co-polymers. Large populations of uniform giant polymersomes with defined, entrapped species can be made by templating of double-emulsions using microfluidics. In the present study, a series of two enzymatic reactions, one inside and the other outside of the polymersome, were designed to induce rupture of polymersomes. We measured how the kinetics of rupture were affected by altering enzyme concentration. These results suggest that protocells with entrapped enzymes can be engineered to secrete contents on cue.

Abstract
The development of a versatile approach for the rapid and sensitive detection of relevant pathogenic bacteria and autonomous signaling of the detection events in reporter hydrogel film coatings is reported. Exploiting chitosan hydrogel films equipped with chromogenic or fluorogenic reporter moieties, the presence of the Gram-negative bacterium Pseudomonas aeruginosa and the Gram-positive bacterium Staphylococcus aureus is sensed within 1 h by detecting the characteristic enzymes α-glucosidase and elastase with limits of detection (LOD) <45 × 10(-9) M and <20 × 10(-9) M, respectively, for this observation time. The values for the LOD are two to three orders of magnitude smaller than the concentrations of the enzymes detected in the corresponding bacterial supernatants. The results show that the covalently conjugated reporter moieties are exclusively and efficiently reacted by the associated enzyme, allowing in principle for discrimination among different types of bacteria. Since high enzyme concentrations are a result of proliferating bacteria, e.g., in wounds or food, and since the selectivity of the reporting function is easily adapted to bacteria of choice, these reporter hydrogels comprise an interesting platform for the rapid detection of bacteria.

Abstract
In this work, a self-reporting hydrogel for the rapid in situ detection of bacterial enzymes is reported. To implement the reporting function for the bacterium Escherichia coli into a film-based sensing format, chitosan hydrogel films on solid backing supports were equipped with a reporting function for the enzyme β-glucuronidase (β-GUS), which is secreted by >98% of all known E. coli strains. Covalent coupling of the fluorogenic substrate 4-methylumbelliferyl-β-D-glucuronide or the complementary chromogenic substrate 4-nitrophenyl-β-D-glucuronide via amide bond formation afforded an attachment that is stable for >24 h under physiological conditions. By contrast, in the presence of β-GUS, the reporter dyes were very rapidly cleaved and produced a signal for the presence of the enzyme, which was detectable by bare eye under appropriate illumination. Detailed investigations of the enzymatic reaction for both types of substrates in neat enzyme solution as well as in bacterial supernatant revealed the apparent reaction kinetics and allowed us to determine the concentration of β-GUS in the supernatant. Under optimized conditions, the 4-methylumbelliferyl-β-D-glucuronide-functionalized hydrogel reported the presence of β-GUS within 15 min with a limit of detection of <1 nM. Finally, the function of the generally applicable hydrogel-film-based sensing approach, which is compatible with polymer-film-based applications, including wound dressings and packaging materials, and is also amenable to address noncultivatable pathogenic bacteria by using appropriate fluorogenic or chromogenic substrates, was demonstrated by direct application with bacterial medium.
