Summary: An effective antioxidant nanoplatform, DSeU@ZIF8, was constructed by encapsulating a selenium-containing glycomimetic into zeolitic-imidazolate framework-8 nanoparticles. The nanoparticles showed remarkable antioxidant capacity and ROS-scavenging activity, and could protect endothelial cells from oxidative stress damage.

Summary: Here, a time-programmed and autonomous synthesis method for zeolitic imidazole framework-8 (ZIF-8) using a methylene glycol-sulfite clock reaction was demonstrated. The induction period of the driving clock reaction, and hence the formation of ZIF-8, can be adjusted by the initial concentration of a reagent in the chemical clock. The autonomously synthesized ZIF-8 exhibited excellent morphology and crystallinity.

Summary: Excessively activated microglia/macrophages (M/Ms) exacerbate inflammation and motor and/or sensory dysfunction after spinal cord injury (SCI). The study shows that FA-PEG/ZIF-8 nanoparticles effectively reduce proinflammatory M/Ms and inflammation in the injured lesion, without targeting other nerve cells. Furthermore, the nanoparticles have minimal toxicity in SCI mice.

Summary: The encapsulation of antigens with ZIF-8 provides advantages in vaccine development, but the synthesis conditions of ZIF-8 can be too harsh for sensitive viral antigens. This study explores the synthesis of ZIF-8 on an environment-sensitive antigen and demonstrates the importance of size and morphology in exerting adjuvant effects.

Summary: In this study, pH-responsive ZIF-8@VAN@BG scaffolds were developed for potentially infected bone repair. The scaffolds exhibited a porous structure, enhanced cell proliferation, and promoted the expression of osteogenic genes. Moreover, the scaffolds showed significant inhibitory effects on Staphylococcus aureus, making them promising for infected bone repair applications.

Summary: This study investigated the vapor-phase layer-by-layer deposition of zeolitic imidazolate framework 8 (ZIF-8) using diethyl zinc, water, and 2-methylimidazole. Two approaches, direct ZIF-8 molecular layer deposition (MLD) and two-step ZIF-8 MLD, were compared. Direct MLD showed nanometer-resolution thickness control and smooth crystalline films, while two-step MLD had reduced deposition time and improved MOF quality. Both approaches were developed in a modified atomic layer deposition reactor for cleanroom compatibility.

Summary: This research explores the possibility of using biolistic delivery as an alternative to needle-and-syringe-based vaccine administration. By encapsulating liposomes in a nano-sized shell made of Zeolitic Imidazolate Framework-8 (ZIF-8), the liposomes are protected from stress and can effectively penetrate the skin. This work demonstrates the mechanical protection provided by ZIF-8 to liposomes and provides a preliminary investigation for using biolistic delivery as an alternative vaccine delivery method.

Summary: A new synthetic strategy has been developed to synthesize MOF composites for efficient degradation of nerve agent simulants without the need for liquid base. One of the composites, Im@MOF-808, exhibited the highest catalytic activity for DMNP hydrolysis in unbuffered aqueous solutions. This research provides a viable solution for the practical implementation of MOF materials in protective equipment for nerve agent detoxification.

Summary: In this study, cellulose acetate (CA)-based nanofiltration membranes modified with zeolitic imidazole framework-8 (ZIF-8) particles were prepared to improve flux and filtration performance. The addition of ZIF-8 resulted in decreased contact angle values, increased pure water flux, higher flux recovery ratio, and reduced fouling in all ZIF-8 doped membranes. Furthermore, the dye removal efficiency increased from 95.2% to 97.7% with the addition of ZIF-8 particles for Reactive Black 5 dye.
