A multimodal Metal-Organic framework based on unsaturated metal site for enhancing antitumor cytotoxicity through Chemo-Photodynamic therapy.

Chemodynamic therapy when combined with chemotherapy opens up a new avenue for treatment of cancer. However, its development is still restricted by low targeting, high dose and toxic side effects. Herein, rational designing and construction of a new multifunctional platform with the core-shell structure 5-ALA@UiO-66-NH-FAM@CP1 (ALA = 5-aminolevulinic acid, CP1 = zirconium-pemetrexed (Zr-MTA)) has been performed.

Applications of ROS-InducedZr-MOFs Platform in Multimodal Synergistic Therapy.

Background: Metal-organic frameworks (MOFs) possess adjustable aperture, high load capacities, tailorable structures, and excellent biocompatibilities for their use as drug delivery carries in cancer therapy. Until now, Zr-MOFs, in particular, combine optimal stability towards hydrolysis and post synthetic modification with low toxicity, and are widely studied for their excellentbiological performance.

Introduction: This review comprises the exploration of Zr-MOFs as drug delivery devices (DDSs) with a focus on various new methods, including chemotherapy (CT), photodynamic therapy (PDT), photothermal therapy (PTT), sonodynamic therapy (SDT), radiotherapy, immunotherapy, gene therapy and related combined therapies, which all generate reactive oxygen species (ROS) to achieve high efficiency of tumor therapy.

Self-adjusted bimetallic zeolitic-imidazolate framework-derived hierarchical magnetic carbon composites as efficient adsorbent for optimizing drug contaminant removal.

The construction of efficient and superior adsorbed materials for the precise removal of hazardous contaminants from water have gained significant attention by the scientific community. In this work, a facile bimetallic zeolitic-imidazolate framework (CoZn-JUC-160) by using self-adjusted strategy (SAS) was developed to synthesize various N-doped Co-based hierarchical porous carbon composites through sacrificial template route. A series of highly porous magnetic materials with well-dispersed or reduced Co particle size have been fabricated by fine tuning the ratio of Co and Zn in the precursors.

Photocatalytic and Ferric Ion Sensing Properties of a New Three-Dimensional Metal-Organic Framework Based on Cuboctahedral Secondary Building Units.

A new three-dimensional microporous metal-organic framework based on Zn(II) clusters with the formula {[Zn(NDC)(μ-OH)]·7DMF} () (HNDC = 1,4-naphthalenedicarboxylic acid) had been synthesized and characterized. The MOF displays an uncommon bsn topology, which is based on a unique heptanuclear Zn(OH)(CO) cluster as a secondary building unit. The MOF had been employed as a photocatalyst for the photodegradation of model organic dyes rhodamine B and methyl violet in light.

A red-emitting indolium fluorescence probe for membranes - flavonoids interactions.

The red-emitting indolium derivative compound (E)-2-(4-(diphenylamino)styryl)-1,3,3-trimethyl-3H-indol-1-ium iodide (H3) was demonstrated as a sensitive membrane fluorescence probe. The probe located at the interface of liposomes when mixed showed much fluorescence enhancement by inhibiting the twisted intramolecular charge transfer state. After ultrasonic treatment, it penetrated into lipid bilayers with the emissions leveling off and a rather large encapsulation efficiency (71.
