Development of Double Hydrophilic Block Copolymer/Porphyrin Polyion Complex Micelles towards Photofunctional Nanoparticles. Polymers (Basel) 2022; 14:polym14235186.

Abstract
The electrostatic complexation between double hydrophilic block copolymers (DHBCs) and a model porphyrin was explored as a means for the development of polyion complex micelles (PICs) that can be utilized as photosensitive porphyrin-loaded nanoparticles. Specifically, we employed a poly(2-(dimethylamino) ethyl methacrylate)-b-poly[(oligo ethylene glycol) methyl ether methacrylate] (PDMAEMA-b-POEGMA) diblock copolymer, along with its quaternized polyelectrolyte copolymer counterpart (QPDMAEMA-b-POEGMA) and 5,10,15,20-tetraphenyl-21H,23H-porphine-p,p',p″,p'''-tetrasulfonic acid tetrasodium hydrate (TPPS) porphyrin. The (Q)PDMAEMA blocks enable electrostatic binding with TPPS, thus forming the micellar core, while the POEGMA blocks act as the corona of the micelles and impart solubility, biocompatibility, and stealth properties to the formed nanoparticles. Different mixing charge ratios were examined aiming to produce stable nanocarriers. The mass, size, size distribution and effective charge of the resulting nanoparticles, as well as their response to changes in their environment (i.e., pH and temperature) were investigated by dynamic and electrophoretic light scattering (DLS and ELS). Moreover, the photophysical properties of the complexed porphyrin along with further structural insight were obtained through UV-vis (200-800 nm) and fluorescence spectroscopy measurements.

Abstract
Solubility and functionality of polymeric materials are essential properties determining their role in any application. In that regard, double hydrophilic copolymers (DHC) are typically constructed from two chemically dissimilar but water-soluble building blocks. During the past decades, these materials have been intensely developed and utilised as, e.g., matrices for the design of multifunctional hybrid materials, in drug carriers and gene delivery, as nanoreactors, or as sensors. This is predominantly due to almost unlimited possibilities to precisely tune DHC composition and topology, their solution behavior, e.g., stimuli-response, and potential interactions with small molecules, ions and (nanoparticle) surfaces. In this contribution we want to highlight that this class of polymers has experienced tremendous progress regarding synthesis, architectural variety, and the possibility to combine response to different stimuli within one material. Especially the implementation of DHCs as versatile building blocks in hybrid materials expanded the range of water-based applications during the last two decades, which now includes also photocatalysis, sensing, and 3D inkjet printing of hydrogels, definitely going beyond already well-established utilisation in biomedicine or as templates.

Abstract
A pyridyl side arm porphyrin incorporating C[Formula: see text] alkyl chains at the periphery of the porphyrin suitable for surface immobilisation on HOPG has been synthesised and tested for two state switching in solution. Temperature switching, involving reversible complexation of a covalently appended pyridyl side arm to the Zn(II) porphyrin, was comprehensively characterised by using variable temperature 1H NMR (-30 to +100[Formula: see text]C) and UV-vis (10 to 90[Formula: see text]C) in toluene. Molecular modelling assisted in understanding strain within the complex.

Abstract
The improvement of the loading content of hydrophilic drugs by polymer nanoparticles (NPs) recently has received increased attention from the field of controlled release. We developed a novel, simply modified, drop-wise nanoprecipitation method which separated hydrophilic drugs and polymers into aqueous phase (continuous phase) and organic phase (dispersed phase), both individually and involving a mixing process. Using this method, we produced ciprofloxacin-loaded NPs by Poly (d,l-lactic acid)-Dextran (PLA-DEX) and Poly lactic acid-co-glycolic acid-Polyethylene glycol (PLGA-PEG) successfully, with a considerable drug-loading ability up to 27.2 wt% and an in vitro sustained release for up to six days. Drug content with NPs can be precisely tuned by changing the initial drug feed concentration of ciprofloxacin. These studies suggest that this modified nanoprecipitation method is a rapid, facile, and reproducible technique for making nano-scale drug delivery carriers with high drug-loading abilities

Abstract
Multi-structure assemblies consisting of gold nanoparticles and porphyrin were fabricated by using diblock copolymer, poly(ethylene glycol)-block-poly(4-vinylpyridine) (PEG-b-P4VP). The copolymer of PEG-b-P4VP was used in the formation of core-shell micelles in water, in which the P4VP block serves as the core, while the PEG block forms the shell. In the micellar core, gold nanoparticle and metalloporphyrin were dispersed through the axial coordination. Structural and morphological characterizations of the complex micelle were carried out by transmission electron microscopy, laser light scatting, and UV-visible spectroscopy. Metalloporphyrin in the complex micelle exhibited excellent photostability by reducing the generation of the singlet oxygen. This strategy may provide a novel approach to design photocatalysts that have target applications in photocatalysis and solar cells.

Abstract
Nanoparticle-based drug delivery systems promise the safety and efficacy of anticancer drugs. Herein, we presented a facile approach to fabricate novel nanoparticles generated by PEG-Chrysin conjugates for the delivery of anticancer drug doxorubicin. Chrysin was immobilized on the terminal group of methoxy poly(ethylene glycol) (mPEG) to form mPEG-Chrysin conjugate. The conjugates were self-assembled into nanoparticles. Doxorubicin (DOX) was loaded in the nanoparticles. The self-assembly, drug release profiles, interactions between nanoparticle and drug, cellular uptake and in vitro anticancer activity of the DOX loaded nanoparticles were investigated. The results showed that the mean diameters of drug loaded nanoparticles were below 200 nm. Strong π-π stacking interaction was tested within the drug loaded nanoparticles. The drug release rate was closely related to the chain length of PEG, shorter PEG chain resulted faster release. The mPEG-Chrysin conjugate was non-toxic to both 3T3 fibroblasts and HepG2 cancer cells. The cellular uptake measurements demonstrated that the mPEG1000-Chrysin nanoparticles exhibited higher capability in endocytosis. The IC50 of drug loaded mPEG1000-Chrysin nanoparticles was 4.4 μg/mL, which was much lower than that of drug loaded mPEG2000-Chrysin nanoparticles (6.8 μg/mL). These nanoparticles provided a new strategy for fabricating antitumor drug delivery systems.

Abstract
Amphiphilic poly(acrylic acid-co-acrylamidophenylboronic acid)-block-poly(2-acryloxyethyl galactose)-block-poly(acrylic acid-co-acrylamidophenylboronic acid) (((PAA-co-PAAPBA)-b-)₂PAEG) copolymer was fabricated: The poly(2-acryloyloxyethyl pentaacetylgalactoside) (PAEAcG) with narrow molecular weight distributions (Mw/Mn≤1.22) was prepared by atom transfer radical polymerization (ATRP) using dibromo-p-xylene (DBX) as initiator. Then the well-defined triblock copolymer poly(t-butyl acrylate)-b-poly(2-acryloyloxyethyl pentaacetylgalactoside)-b-poly(t-butyl acrylate) (PtBA-b-PAEAcG-b-PtBA) was synthesized by ATRP of tBA using PAEAcG homopolymer with dibromo end groups as macroinitiator. After hydrolysis of t-butyl acrylate block, amide linkage and deacetylation, the final copolymer ((PAA-co-PAAPBA)-b-)₂PAEG was obtained. Because of characteristics of three different segments, amphiphilic ((PAA-co-PAAPBA)-b-)₂PAEG can self-assemble into pH- and glucose-responsive nanoparticles studied by dynamic light scattering (DLS) and transmission electron microscopy (TEM). Furthermore, the in vitro release profiles of insulin also revealed obvious pH- and glucose-sensitivity of the nanoparticles. The analysis of cell viability suggested that the copolymer nanoparticles had good cytocompatibility.

Abstract
New thermal- and photoresponsive core-shell nanogel particles were obtained from self-assembly in aqueous solution of a double-hydrophilic block copolymer (DHBCP) of which the two blocks could be photo-cross-linked via the reversible photodimerization and photocleavage of coumarin moieties. The diblock copolymer, consisting of poly[N,N-dimethylacrylamide-co-4-methyl-[7-(methacryloyl)oxyethyloxy]coumarin] and poly[N-isopropylacrylamide-co-4-methyl-[7-(methacryloyl)oxyethyloxy]coumarin] (P(DMA-co-CMA)-b-P(NIPAM-co-CMA)), was synthesized by using reversible addition-fragmentation chain transfer (RAFT) polymerization. At T > LCST of the P(NIPAM-co-CMA) block, core-shell micelles were formed and UV light irradiation at λ > 310 nm resulted in cross-linking of both the micelle core of P(NIPAM-co-CMA) and the micelle shell of P(DMA-co-CMA); subsequent cooling of the solution to T < LCST gave rise to water-soluble, swollen nanogel particles. Upon UV light irradiation at λ < 260 nm, the decrease of cross-linking density could increase the swelling of nanogel particles by ∼23% in diameter. By alternating irradiation with the different wavelengths, the average hydrodynamic diameter of nanogel particles was tunable between ∼58 and ∼47 nm. Interestingly, upon further cooling of the solution, aggregation occurred for nanogel particles with a moderate cross-linking density (10%-40% dimerization of coumarin moieties). Therefore, such core- and shell-cross-linked nanogel could display both "intraparticle" LCST (solubility of polymer chains forming the core) and "interparticle" UCST (solubility of particles). The possible mechanism and the effect of dimerization degree on the UCST behavior were discussed.

Abstract
Using a layer-by-layer (LbL) approach, this work presents the preparation of hollow microcapsules with a membrane constructed entirely from a cationic/zwitterionic pair of pH-responsive block copolymer micelles. Our previous work with such systems highlighted that, in order to retain the responsive nature of the individual micelles contained within the multilayer membranes, it is important to optimize the conditions required for the selective dissolution of the sacrificial particulate templates. Consequently, here, calcium carbonate particles have been employed as colloidal templates as they can be easily dissolved in aqueous environments with the addition of chelating agents such as ethylenediaminetetraacetic acid (EDTA). Furthermore, the dissolution can be carried out in solutions buffered to a desirable pH so not to adversely affect the pH sensitive micelles forming the capsule membranes. First, we have deposited alternating layers of anionic poly[2-(dimethylamino)ethyl methacrylate-block-poly(2-(diethylamino)ethyl methacrylate)] (PDMA-PDEA) and cationic poly(2-(diethylamino)ethyl)methacrylate-block-poly(methacrylic acid) (PDEA-PMAA) copolymer micelles onto calcium carbonate colloidal templates. After deposition of five micelle bilayers, addition of dilute EDTA solution resulted in dissolution of the calcium carbonate and formation of hollow polymer capsules. The capsules were imaged using atomic force microscopy (AFM) and scanning electron microscopy (SEM), which shows that the micelle/micelle membrane is sufficiently robust to withstand dissolution of the supporting template. Quartz crystal microbalance studies were conducted and provide good evidence that the micelle multilayer structure is retained after EDTA treatment. In addition, a hydrophobic dye was incorporated into the micelle cores prior to adsorption. After dissolution of the particle template, the resulting hollow capsules retained a high concentration of dye, suggesting that the core/shell structure of the micelles remains intact. Finally, thermogravimetric analysis (TGA) of dried capsules confirmed complete removal of the sacrificial inorganic template. As far as we are aware, this is the first demonstration of LbL assembled capsules composed entirely from responsive block copolymer micelles. The results presented here when combined with our previous findings demonstrate that such systems have potential application in the encapsulation and triggered release of actives.

Abstract
A well-defined ABC triblock copolymer, poly(2-(2-methoxyethoxy)ethyl methacrylate)-b-poly(2-(dimethylamino)ethyl methacrylate)-b-poly(2-(diethylamino)ethyl methacrylate) (PMEO2MA-b-PDMA-b-PDEA), was synthesized via sequential atom transfer radical polymerization using ethyl 2-bromoisobutyrate as the initiator. Reacting the triblock precursor with propargyl bromide in anhydrous tetrahydrofuran yielded PMEO2MA-b-P(DMA-co-QDMA)-b-PDEA triblock copolymer with "clickable" moieties, where QDMA was quaternized DMA residues. PMEO2MA-b-P(DMA-co-QDMA)-b-PDEA triblock copolymer exhibited "schizophrenic" micellization behavior in aqueous solution, forming three-layer onion-like PMEO2MA-core and PDEA-core micelles upon proper adjustment of the solution pH and temperature. For temperature-induced formation of PMEO2MA-core micelles at acidic pH, the critical micellization temperature can be tuned by incorporating oligo(ethylene glycol) methyl ether methacrylate (OEGMA; the mean degree of polymerization was 8-9) residues into the PMEO2MA block, shifting from 38 to 43 degrees C as the OEGMA contents varied in the range of 0-10 mol %. In both types of micelles, the inner shell layer consisted of the middle P(DMA-co-QDMA) segment. Subsequently, cross-linking with tetra(ethylene glycol) diazide via click chemistry in the presence of copper catalysts led to the facile preparation of two types of shell-cross-linked (SCL) micelles with "inverted" structures in purely aqueous solution. The cores and coronas of SCL micelles exhibited multiresponsive swelling/shrinking and collapse/aggregation behavior, respectively. To the best of our knowledge, this represents the first report of the fabrication of two types of SCL micelles with inverted structures from a single schizophrenic water-soluble triblock copolymer in purely aqueous solution.

Abstract
Dual-drug delivery systems are investigated for combined therapy with drugs having distinct therapeutic effects. However, the majority of current dual-drug delivery systems are designed for simultaneous release of two different drugs; the release of each individual drug cannot be controlled. In this study, we have demonstrated a novel dual-drug delivery system based on mesoporous bioactive glass/polypeptide graft copolymer nanomicelle composites. Water-soluble gentamicin and fat-soluble naproxen were used as model drugs in the study of this system. A pH-controlled release of individual drugs was achieved by the predominant release of gentamicin from mesoporous bioactive glass in an acid environment and fast release of naproxen in an alkaline environment from polypeptide nanomicelles. Our results suggest that the mesoporous bioactive glass/PBLG-g-PEG nanomicelle composites can be used as a dual-drug delivery system, and that the individual drug release can be controlled by the pH of the surrounding environment.
