Therapeutic Potency of NO Loaded into Anticancer Copper Metal-Organic Framework through Nonclassical Hydrogen Bonding.

Metal-organic frameworks (MOFs) are potential exogenous scaffolds for therapeutic nitric oxide (NO) delivery because they can store drug or bioactive gas molecules within pores or on active metal sites. Herein, we employed a Cu-MOF coordinated with glutarate (glu) and 1,2-bis(4-pyridyl)ethane (bpa) to obtain NO-loaded Cu-MOF (NO⊂Cu-MOF). NO loading transformed the space group of Cu-MOF from monoclinic 2/ to triclinic through nonclassical hydrogen bonding with glu and bpa.

Controllable Nitric Oxide Storage and Release in Cu-BTC: Crystallographic Insights and Bioactivity.

Crystalline metal-organic frameworks (MOFs) are extensively used in areas such as gas storage and small-molecule drug delivery. Although Cu-BTC (, MOF-199, BTC: benzene-1,3,5-tricarboxylate) has versatile applications, its NO storage and release characteristics are not amenable to therapeutic usage. In this work, micro-sized Cu-BTC was prepared solvothermally and then processed by ball-milling to prepare nano-sized Cu-BTC ().

Delivery of nitric oxide-releasing silica nanoparticles for revascularization and functional recovery after acute peripheral nerve crush injury.

Nitric oxide (NO) has been shown to promote revascularization and nerve regeneration after peripheral nerve injury. However, in vivo application of NO remains challenging due to the lack of stable carrier materials capable of storing large amounts of NO molecules and releasing them on a clinically meaningful time scale. Recently, a silica nanoparticle system capable of reversible NO storage and release at a controlled and sustained rate was introduced.

Potential Protective Effect of Nitric Oxide-Releasing Nanofibers in Hypoxia/Reoxygenation-Induced Cardiomyocyte Injury.

Nitric oxide (NO) is involved in several physiological processes including vasodilation, angiogenesis, immune response, and wound healing, as well as preventing ischemia/reperfusion injury in many organs such as the heart, liver, lungs, and kidneys. Recently, various NO delivery systems such as nanoparticles, nanorods, and nanofibers have been widely studied as potential therapeutic agents. In particular, NO-releasing nanofibers have been attracting much attention for various medicinal applications including regenerative medicine, wound dressings, and coatings for implantable medical devices, due to their flexible and open architectures.

Electrodeposition of SnO2 on FTO and its Application in Planar Heterojunction Perovskite Solar Cells as an Electron Transport Layer.

We report the performance of perovskite solar cells (PSCs) with an electron transport layer (ETL) consisting of a SnO thin film obtained by electrochemical deposition. The surface morphology and thickness of the electrodeposited SnO films were closely related to electrochemical process conditions, i.e.
