    Feedback enhanced tumor targeting delivery of albumin-based nanomedicine to amplify photodynamic therapy by regulating AMPK signaling and inhibiting GSTs

    481-485页
    查看更多>>摘要：Oxidative therapies receive a limited antitumor efficiency due to the insufficient reactive oxygen species(ROS)levels at focal sites and the evolvement of antioxidant defense systems.Herein,we develop an albumin-based nanomedicine to co-deliver chlorin e6(Ce6)and COH-SR4(CS),which can simultaneously enhance the yield and lethality of intracellular ROS for amplified photodynamic therapy(PDT).In which,CS acts as both an activator of AMP-activated protein kinase(AMPK)and an inhibitor of glutathione S-transferases(GSTs).Benefiting from it,the prepared HSA-Ce6@COH-SR4(HCCS)enables positive feed-back uptake by promoting AMPK phosphorylation,leading to rapid and extensive tumor accumulation of drugs.As a result,HCCS obviously increases the ROS production to elevate intracellular oxidative stress.Furthermore,HCCS can inhibit GSTs to disturb the antioxidant defense system of tumor cells,intensifying the oxidative damage of ROS.Ultimately,the PDT of HCCS is significantly strengthened by improving the ROS yield and lethality,which greatly declines the proliferation of breast cancer in vivo.This study may open a window in the development of drug co-delivery system for enhanced oxidative therapy of tumors.

    486-490页
    查看更多>>摘要：Bioprinting is emerging as an advanced tool in tissue engineering.However,there is still a lack of bioinks able to form hydrogels with desirable bioactivities that support positive cell behaviors.In this study,modified plasma proteins capable of forming hydrogels with multiple biological functions are developed as bioinks for digital light processing(DLP)printing.The Plasma-MA(BM)was synthesized via a one-pot method through the reaction between the fresh frozen plasma and methacrylic anhydride.The methacry-lated levels were observed to influence the physical properties of BM hydrogels including mechanical properties,swelling,and degradation.The photo-crosslinked BM hydrogels can sustainedly release vascu-lar endothelial growth factor(VEGF)and exhibit positive biological effects on cell adhesion and prolifer-ation,and cell functionality such as tube formation of human umbilical vein endothelial cells(HUVECs),and neurite elongation of rat pheochromocytoma cells(PC12).Meanwhile,BM hydrogels can also induce cell infiltration,modulate immune response,and promote angiogenesis in vivo.Moreover,the plasma bioinks can be used to fabricate customized scaffolds with complex structures through a DLP printing process.These findings implicate that the modified plasma with growth factor release is a promising candidate for bioprinting in autologous and personalized tissue engineering.

    Chlorogenic acid supported strontium polyphenol networks ensemble microneedle patch to promote diabetic wound healing

    Peizhe LiQiaoling LiuMengyu PeiYuci Gan...
    491-497页
    查看更多>>摘要：Delayed or non-healing of diabetic wounds is a significant complication,often attributed to high glucose-induced M1 macrophage accumulation,impaired angiogenesis,and reactive oxygen species(ROS)buildup.Addressing this,we introduced a strontium polyphenol network microneedle patch(SrC-MPNs@MN-PP)for percutaneous drug delivery.This patch,formulated with polymer poly(γ-glutamic acid)(γ-PGA)and epsilon-poly-L-lysine(ε-PLL),incorporates strontium polyphenol networks(SrC-MPNs).The release of chlorogenic acid(CGA)from SrC-MPNs not only neutralizes ROS,but strontium ions also foster angiogen-esis.Consequently,SrC-MPNs@MN-PP can ameliorate the diabetic wound microenvironment and expedite healing.

    Producing circularly polarized luminescence by radiative energy transfer from achiral metal-organic cage to chiral organic molecules

    498-502页
    查看更多>>摘要：The development of circularly polarized luminescence(CPL)materials with high performance is signifi-cantly important.Herein,we develop a facial strategy for fabricating a CPL-active system by employing an achiral luminescent metal-organic cage(MOC)and chiral boron dipyrromethene(BODIPY)molecules.CPL is achieved by taking advantage of the radiative energy transfer process,in which BODIPY molecules act as energy acceptors and MOCs act as donors.The CPL performance(maximum luminescence dissymme-try factor up to±1.5x10-3)can be tuned by adjusting the ratio between MOCs and BODIPY.White-light emission with the CPL feature is obtained by using a ternary system including MOC,chiral BODIPY,and Rhodamine B.The present work provides a facile and universal strategy to construct a CPL-active system by integrating achiral luminophores and chiral molecules.

    Chiral induction and Sb3+doping in indium halides to trigger second harmonic generation and circularly polarized luminescence

    503-507页
    查看更多>>摘要：Recently,organic-inorganic hybrid metal halides(HMHs)have attracted extensive attention as promis-ing multifunctional materials by virtue of their structural diversity and tunable photophysical properties.However,it remains a challenge to design HMHs with specific functions on demand.Herein,by introduc-ing R/S-methylbenzylamine(R/S-MBA)and doping Sb3+,we have achieved both second harmonic gen-eration(SHG)and circularly polarized luminescence(CPL)properties in lead-free indium halides.The introduction of chiral organic cations can break the symmetry and induce the indium halides to crys-tallize in the chiral space group.The Sb3+with ns2 electronic configuration can serve as the dopants to promote the formation of self-trapped excitons,so as to activate highly efficient luminescence.As a re-sult,the as-prepared Sb3+doped(R/S-MBA)3InCl6 show not only SHG responses but also CPL signals with luminescence dissymmetry factor of-5.3 × 10-3 and 4.7 × 10-3.This work provides a new inspiration for the exploitation of chiral multifunctional materials.

    Tailored ionically conductive graphene oxide-encased metal ions for ultrasensitive cadaverine sensor

    Ying ChenLi LiJunyao ZhangTongrui Sun...
    508-513页
    查看更多>>摘要：Intelligent chemical sensors have been extensively used in food safety and environmental assessment,while limited sensitivity and homogeneity bring about huge obstacles to their practical application.Herein,novel ionically conductive sensitive materials were elaborately designed based on metal ion decorated graphene oxide(GO)via a facile and general in-situ spin-coating strategy,where the abundant functional groups(-OH and-COOH)of GO layer could provide natural binding sites for various bivalent metal cations(such as Cu2+,Ni2+,Zn2+,Co2+,and Mg2+)through coordination and electrostatic inter-action.The intercalated metal cations on the layered GO nanosheets can be regarded as charge carriers and complexation with targeted gas(cadaverine,Cad),which is a typical metabolites production and food degradants.By contrast,the designed GO@Cu(Ⅱ)sensor exhibited the optimal sensing performance toward Cad molecules at room temperature,including ultra-low detection limit(ca.3 nL),excellent sensitivity,and rapid low concentration detection rate(only 16 s).Interestingly,the sensor exhibited an irreversible and specific response toward Cad,while it showed a transient and reversible response to other interfering gases,implying its outstanding selectivity.In addition,the GO@Cu(Ⅱ)sensor enabled real-time monitoring of the decay progression of cheese,and it exhibited great potential for large-scale production via its excellent homogeneity.It provides an efficient approach to tailoring intelligent chemical sensors for real-time food safety monitoring and human health warning.

    514-519页
    查看更多>>摘要：Metal-organic frameworks(MOFs)functionalized with open metal sites(OMSs)have received widespread attention in various applications due to their fascinating electronic properties and unique interactions with guest molecules.However,rational tailoring of the coordination environment of metal nodes dur-ing the synthesis of MOFs remains a great challenge due to their tendency of saturated coordination with linkers.Herein,we reported the construction of three new MOFs featuring unsaturated Cu(Ⅱ)sites,namely[Cu(HCOO)(pzta)]n(HL-1),{[Cu(PTA)0.5(pzta)(H2O)]·2H2O}n(HL-2)and[Cu(NA)0.5(pzta)]n(HL-3)(Hpzta=3-pyrazinyl-1,2,4-triazole;PTA=terephthalic acid;NA=1,4-naphthalene dicarboxylic acid),based on the mixed-linker strategy via specific selection of versatile Hpzta ligand and carboxylate ligands.Re-markably,the obtained MOFs exhibited excellent activity and good recyclability for the catalytic reduction of nitroaromatics under mild conditions(25 ℃ and 1 atm).In particular,the complete conversion of 4-nitrophenol(4-NP)took only 30 s on HL-2,reaching a record-high TOF value compared with previously reported metal catalysts.The combined experimental and theoretical studies on HL-2 revealed that the open Cu site with positive-charged nature could improve the adsorption and subsequent electron trans-port between the substrates,and was responsible for the outstanding performance.This work shined lights on the further enhancement of performance for MOFs through rational OMSs construction.

    520-525页
    查看更多>>摘要：In the development of 3D conductive frameworks for lithium metal anode(LMA),two models have been proposed:top growth model and bottom-up growth model.However,Li tends to accumulate on the top of these 3D frameworks with homogenous lithiophilicity(top growth)and Li dendrite still forms.To address this issue,some researchers have focused on developing 3D frameworks with gradient lithio-philicity,which realized bottom-up growth of Li.Nevertheless,partial Li nucleation sites on the top of these frameworks were missed.Inspired by the two models talked above,this work firstly proposed a novel intermittent lithiophilic model for lithium deposition.To demonstrate the feasibility of this model,a bimetallic metal-organic frameworks derived ZnMn2O4-MnO nanoparticles were grown on carbon cloth for LMA.It can cycle stably under ultra-high current and areal capacity(10mA/cm2,10 mAh/cm2).The in-situ optical microscopy(OM)was conducted to observe the Li deposition behavior,no dendrite was found during 80 h in ester-based electrolyte while the pure Li only cycled for 2 h.What is more,it can also be well-coupled with LiNi0.8Co0.1Mn0.1O2(NCM811)cathode and solid-state electrolyte,which further prove the advantages of the intermittent model for the development of LMAs with high safety and high energy density.

    A weakly-solvated ether-based electrolyte for fast-charging graphite anode

    Xiao ZhuYanbing MoJiawei ChenGaopan Liu...
    526-532页
    查看更多>>摘要：Weakly-solvated electrolytes(WSEs)utilizing solvents with weak coordination ability offer advantages for low-potential graphite anode owing to their facile desolvation process and anions-derived inorganic-rich solid electrolyte interphase(SEI)film.However,these electrolytes face challenges in achieving a balance between the weak solvation affinity and high ionic conductivity,as well as between rigid inorganic-rich SEI and flexible SEI for long-term stability.Herein,we introduce 1,3-dioxolane(DOL)and lithium bis(trifluoromethanesulfonyl)-imide(LiTFSI)as functional additives into a WSE based on nonpolar cyclic ether(1,4-dioxane).The well-formulated WSE not only preserves the weakly solvated features and anion-dominated solvation sheath,but also utilizes DOL to contribute organic species for stabilizing the SEI layer.Benefitting from these merits,the optimized electrolyte enables graphite anode with excellent fast-charging performance(210 mAh/g at 5 C)and outstanding cycling stability(600 cycles with a capacity retention of 82.0％at room temperature and 400 cycles with a capacity retention of 80.4％at high temper-ature).Furthermore,the fabricated LiNi0.8Co0.1Mn0.1O2‖graphite full cells demonstrate stable operation for 140 cycles with high capacity retention of 80.3％.This work highlights the potential of tailoring solvation sheath and interphase properties in WSEs for advanced electrolyte design in graphite-based lithium-ion batteries.

    查看更多>>摘要：For treatment of sulfion-containing wastewater,coupling the electrochemical sulfion oxidation reaction(SOR)with hydrogen evolution reaction(HER)can be an ideal way for sulfur and H2 resources recovery.Herein,we synthesize a metal-modified carbon nanotube arrays electrode(Co@N-CNTs/CC)for SOR and HER.This electrode has excellent performance for SOR and HER attributed to the unique array structure.It can achieve 99.36 mA/cm2 at 0.6 V for SOR,and 10mA/cm2 at 0.067 V for HER.Density functional theory calculations verify that metal modification is able to regulate the electronic structure of carbon nanotube,which is able to optimize the adsorption of intermediates.Employed Co@N-CNTs/CC as bifunctional elec-trodes to establish a hybrid electrolytic cell can reduce about 67％of energy consumption compared with the traditional water splitting electrolytic cell.Finally,the hybrid electrolytic cell is used to treat actual sulfion-containing wastewater,achieving the sulfur yield of 30 mg h-1 cm-2 and the hydrogen production of 0.64mL/min.
