The four-arm star copolymers poly(methacrylic acid)-poly(2-hydroxyethyl methacrylate-disulfide similar to)-poly(poly(ethylene glycol) methyl ether methacrylate) (4AS-PMAA(x)-(PHEMA-SS similar to)(y)-PPEGMA(z)) with four different block ratios were synthesized and could self-assembled into cross-linked polymer micelles for the exploration of the structure-property relationship. The cross-linked polymer micelles in aqueous solution had low critical micelle concentration (CMC) values (1.9-4.6 mg/L), which exhibited better stability than non-cross-linked micelles. The CMC value decreased with the increase of the length of inner PMAA core and hydrophobic PHEMA cross-linked middle layer. The blank and doxorubicin (DOX)-loaded micelles with different block ratios were prepared by dialysis with the particle sizes of 120-240 nm. The longer inner PMAA core and cross-linked middle layer enhanced the drug loading content (DLC) results and led to relatively bigger particle sizes of polymer micelles. The in vitro DOX release data revealed that DOX-loaded micelles had low DOX cumulative release percentages of 18-37% after 110 h at pH 7.4, but up to 83-90% when introducing reductant GSH at pH 5.0. The 4AS-PMAA(21.2)-(PHEMASS approximate to)(13.1)-PPEGMA(5.1) micelles with the longest PMAA core had the largest cumulative release of 90.1%. The DOX release process and mechanism of the micelles at different conditions fitted well with the semi-empirical equation. Overall, the results demonstrated that the block ratios and pH/redox-responsiveness of these four-arm star copolymers could be well-controlled and their self-assembled cross-linked micelles as anticancer drug carrier system could be improved by optimizing the different ratios.

The combination of two imaging probes on the same biomolecule gives access to targeted bimodal imaging agents that can provide more accurate diagnosis, complementary information, or that may be used in different applications, such as nuclear imaging and fluorescence guided surgery. In this study, we demonstrate that dichlorotetrazine, a small, commercially available compound, can be used as a modular platform to easily assemble various imaging probes. Doubly labeled tetrazines can then be conjugated to a protein through a biorthogonal IEDDA reaction. A series of difunctionalized tetrazine compounds containing various chelating agents and fluorescent dyes was synthesized. As a proof of concept, one of these bimodal probes was conjugated to trastuzumab, previously modified with a constrained alkyne group, and the resulting dual-labeled antibody was evaluated in a mouse model, bearing a HER2-positive tumor. A significant uptake into tumor tissues was observed in vivo, by both SPECT-CT and fluorescence imaging, and confirmed ex vivo in biodistribution studies.

A compressive strain applied to bilayer films (e.g., a thin film adhered to a thick substrate) can lead to buckled or wrinkled morphologies, which has many important applications in stretchable electronics, anticounterfeit technology, and high-precision micrometrology and nano-metrology. A number of buckling-based metrology methods have been developed to quantify the residual stress and viscoelastic properties of polymer thin films. However, in some systems (e.g., solvent-induced swelling or thermal strain), the compressive strain is unknown or difficult to measure. We present a quantitative method of measuring the compressive strain of wrinkled polymer films and coatings with knowledge of the skin thickness, wrinkle wavelength, and wrinkle amplitude. The derived analytical expression is validated with a well-studied model system, e.g., a stiff, thin film bonded to a thick, compliant substrate. After validation, we use our expression to quantify the applied swelling strain of previously reported wrinkled poly(styrene-alt-maleic anhydride) brush surfaces. Finally, the applied strain is used to rationalize the observed persistence length of aligned wrinkles created during atomic force microscopy lithography and subsequent solvent exposure.

The reduced graphene oxide (rGO) modified natural rubber composite (NR) filled with high contents of silica was prepared by a wet compounding and latex mixing process using a novel interface modifier cystamine dihydrochloride (CDHC) with coagulation ability. CDHC acts as a coagulation agent through electrostatic interaction with rGO, SiO2, and latex rubber particles during the latex-based preparation process, while in the obtained silica/graphene/natural rubber composites, CDHC acts as an interface modifier. Compared with the composites prepared by the conventional mechanical mixing method, the dispersion of both rGO and SiO2 in the composites made by a wet compounding and latex mixing process is improved. As a result, the obtained silica/graphene/natural rubber composite prepared by this new method has good comprehensive properties. A Dynamic Mechanical Test suggests that the tan delta values of the composites at 60 degrees C decrease, indicating a low rolling resistance with increasing the graphene content at a low strain, but it increases at a higher strain. This unique feature for this material provides an advantage in the rubber tire application.

A water-soluble cyclophane dimer having two disulfide groups as a reduction-responsive cleavable bond as well as several acidic and basic functional groups as a pH-responsive ionizable group 1 was successfully synthesized. It was found that 1 showed pH-dependent guest-binding behavior. That is, 1 strongly bound an anionic guest, 6-p-toluidinonaphthalene-2-sulfonate (TNS) with binding constant (K/M-1) for 1:1 host-guest complexes of 9.6 x 10(4) M-1 at pH 3.8, which was larger than those at pH 7.4 and 10.7 (6.0 x 10(4) and 2.4 x 10(4) M-1, respectively), indicating a favorable electrostatic interaction between anionic guest and net cationic 1. What is more, release of the entrapped guest molecules by 1 was easily controlled by pH stimulus. Large favorable enthalpies (Delta H) for formation of host-guest complexes were obtained under the pH conditions employed, suggesting that electrostatic interaction between anionic TNS and 1 was the most important driving force for host-guest complexation. Such contributions of Delta H for formation of host-guest complexes decreased along with increased pH values from acidic to basic solutions. Upon addition of dithiothreitol (DTT) as a reducing reagent to an aqueous PBS buffer (pH 7.4) containing 1 and TNS, the fluorescence intensity originating from the bound guest molecules decreased gradually. A treatment of 1 with DTT gave 2, having less guest-binding affinity by the cleavage of disulfide bonds of 1. Consequently, almost all entrapped guest molecules by 1 were released from the host. Moreover, such reduction-responsive cleavage of 1 and release of bound guest molecules was performed more rapidly in aqueous buffer at pH 10.7.

Sequence specific molecules with high folding ability (i.e., foldamers) can be used to precisely control the distribution and projection of side chains in space and have recently been introduced as tailored systems for delivering nucleic acids into cells. Designed oligourea sequences with an amphipathic distribution of Arg- and His-type residues were shown to form tight complexes with plasmid DNA, and to effectively promote the release of DNA from the endosomes. Herein, we report the synthesis of new cell-penetrating foldamer sequences in which the foldamer segment is conjugated via a reducible disulfide bond to a ligand that binds cell-surface expressed nucleoproteins with the idea that this system could facilitate both assemblies with nucleic acids and cell entry. This new system was evaluated for delivery of DNA in several cell lines and was found to compare favorably with all comparators tested (DOTAP and b-PEI as well as a number of known cell penetrating peptides) in various cell lines and particularly in culture medium containing up to 50% of serum. These results suggest that this dual molecular platform which is long lasting and noncytotoxic could be of practical use for in vivo applications.

Chemo-photodynamic combined therapy is promising in cancer treatment, although low tissue penetration of visible light for activating photosensitizers (e.g., chlorin e6, Ce6) limited its broad applications. Combination of upcoverting nanoparticles (UCNPs) with the photosensitizers endows us with the possibility to utilize highly tissue penetrable near-infrared light; nevertheless, the mismatch between absorption of common photosensitizers (lambda(abs), mainly red) and emission of UCNPs (lambda(em), mainly green) resulted in low energy utilization and unsatisfied therapeutic efficacy in the current UCNP-PDT (photodymanic therapy) platforms. To resolve this problem, herein, we construct polymer-UCNP hybrid micelles (PUHMs) for codelivery of doxorubicin (DOX) and Ce6, and systemically studied the effects of spectral match between lambda(em) of UCNPs and lambda(abs) of Ce6 on efficiency of synergistic chemo-photodynamic therapy. Compared with spectrally mismatched PUHMs, the spectrally matched PUHMs can significantly enhance the utilization efficiency of upconverted emission energy to activate the photosensitizers and generate more reactive oxygen species (ROS) for enhanced photodynamic therapy. Meanwhile, as the assembled structure of PUHMs can be destroyed by the oxidation of ROS upon 980 nm laser irradiation because of the hydrophobic-hydrophilic transformation of poly(propylene sulfide) (PPS) segment, the spectrally matched PUHMs triggered faster release of DOX, thus resulting in more effective chemotherapy. As a result, the spectrally matched PUHMs induced more prominent cytotoxicity and superior synergistic therapeutic effect for cancer cells in vitro. Our results demonstrated that such spectrally matched PUHMs provide us with an effective strategy for photodynamic-chemo synergistic therapy.

Cancer cells have reductive and acidic environments as compared to the normal body cells. Development of reductive/acidic responsive polymersomes will play a major role in cancer therapy to trigger the release of the loaded drug. In our work, we synthesized three different reductive/acidic dual-responsive polymers, poly[(mPEG-SS-amino) (N,N-diisopropylethylenediamino)phosphazenes] (PPDPs) in different mole ratios of side groups. These PPDPs were characterized by H-1 NMR, P-31 NMR, FT-IR and GPC. After that, the PPDPs were allowed to self-assemble into drug-loaded polymersomes with high loading content and encapsulation efficiency of hydrophilic/hydrophobic anticancer drugs. The hydrophilic anticancer drug doxorubicin hydrochloride (DOX center dot HCl) and hydrophobic drug doxorubicin were used. These PPDPs-based polymersomes showed reductive/acidic stimuli-responsive release of anticancer drugs. Moreover, these polymersomes also exhibited suitable hydrodynamic diameters, which will facilitate the longtime circulation in bloodstream due to avoiding renal clearance and close contact to the tumor cells in vascular sections due to enhanced permeability and retention effect. Collectively, these developed polymersomes may provide an effective platform for anticancer drugs delivery.
