Some infectious or malignant diseases such as cancers are seriously threatening the health of human beings all over world. The commonly used antibiotic therapy cannot effectively treat these within a short time, and also bring about adverse effects drug resistance immune system damage during long-term systemic treatment. Phototherapy is an emerging antibiotic-free strategy to diseases. Upon light irradiation, phototherapeutic agents can generate cytotoxic reactive oxygen species (ROS) induce temperature increase, which leads death targeted cells. These two kinds killing strategies referred photodynamic (PDT) photothermal (PTT), respectively. So far, many photo-responsive have been developed. Among them, metal-organic framework (MOF) becoming one most promising materials because its structure chemical compositions be easily modulated achieve specific functions. MOFs intrinsic ability under rational design MOF construction, serve carrier therapeutic agents, owing tunable porosity. provide feasibility for various combined therapies targeting methods, improves efficiency phototherapy. In this review, we firstly investigated principles phototherapy, comprehensively summarized recent advances in PDT, PTT synergistic therapy, from construction modification. We expect that our demonstration will shed on future development field, it step closer clinical trials.

Cascade Reaction System Integrating Single-Atom Nanozymes with Abundant Cu Sites for Enhanced Biosensing

Analytical Chemistry, Journal Year: 2020, Volume and Issue: 92(4), P. 3373 - 3379

Published: Jan. 16, 2020

Single-atom nanozymes (SAzymes), as novel with atomically dispersed active sites, are of great importance in the development for their high catalytic activities, maximum utilization efficiency metal atoms, and simple model sites. Herein, peroxidase-like SAzymes high-concentration Cu sites on carbon nanosheets (Cu–N–C) were synthesized through a salt-template strategy. With densely distributed atoms (∼5.1 wt %), Cu–N–C exhibit remarkable activity to mimic natural peroxidase. Integrating acetylcholinesterase choline oxidase, three-enzyme-based cascade reaction system was constructed colorimetric detection acetylcholine organophosphorus pesticides. This work not only provides strategy synthesize abundant but also gives some new insights robust nanozyme biosensing systems.

Published: Nov. 20, 2019

Abstract Glucose oxidase (GOx) can react with intracellular glucose and oxygen (O 2 ) to produce hydrogen peroxide (H O gluconic acid, which cut off the nutrition source of cancer cells consequently inhibit their proliferation. Therefore, GOx is recognised as an ideal endogenous oxido‐reductase for starvation therapy. This process further regulate tumor microenvironment by increasing hypoxia acidity. Thus, offers new possibilities elaborate design multifunctional nanocomposites However, natural expensive prepare purify exhibits immunogenicity, short in vivo half‐life, systemic toxicity. Furthermore, highly prone degrade after exposure biological conditions. These intrinsic shortcomings will undoubtedly limit its biomedical applications. Accordingly, some nanocarriers be used protect from surrounding environment, thus controlling or preserving activity. A variety including hollow mesoporous silica nanoparticles, metal–organic frameworks, organic polymers, magnetic nanoparticles are summarized construction GOx‐based multimodal synergistic In addition, current challenges promising developments this area highlighted.

ACS Nano, Journal Year: 2022, Volume and Issue: 16(2), P. 3105 - 3118

Published: Jan. 18, 2022

The clinical application of photothermal therapy (PTT) is severely limited by the tissue penetration depth excitation light, and enzyme hampered its low therapeutic efficiency. As a two-dimensional ultrathin nanosheet with high absorbance in near-infrared-II (NIR-II) region, titanium carbide (Ti3C2) can be used as substrate to anchor functional components, like nanozymes nanodrugs. Here, we decorate Pt artificial on Ti3C2 nanosheets synthesize Ti-based MXene nanocomposites (Ti3C2Tx-Pt-PEG). In tumor microenvironment, nanoparticles exhibit peroxidase-like (POD-like) activity, which situ catalyze hydrogen peroxide generate hydroxyl radicals (•OH) induce cell apoptosis necrosis. Meanwhile, composite shows desirable effect upon NIR-II light irradiation power density (0.75 W cm-2). Especially, POD-like activity significantly enhanced elevated temperature arising from Ti3C2Tx. Therefore, satisfactory synergistic PTT/enzyme has been accomplished, accompanied an applicable photoacoustic imaging capability monitor guide process. This work may provide approach for hyperthermia-amplified nanozyme catalytic therapy, especially based metal catalysts nanocomposites.
