Aflatoxin B1 (AFB1) has strong carcinogenicity, mutagenicity, and teratogenicity even at low concentrations, presenting a major risk to food safety and human health, hence, it is crucial to develop a sensitive detection technique for AFB1. Consequently, cadmium telluride (CdTe) quantum dots conjugated with AFB1 aptamers serve as fluorescent signal probes, whereas FeO@UiO-66-NH nanocomplexes are employed as magnetic carriers and fluorescence quenchers. FeO@UiO-66-NH reduces background signal interference, thereby enhancing detection sensitivity and Förster Resonance Energy Transfer (FRET) efficiency.

Mesenchymal stem cells (MSCs) are pluripotent stem cells with self-renewal. They play a critical role in cell therapy due to their powerful immunomodulatory and regenerative effects. Recent studies suggest that one of the key therapeutic mechanisms of MSCs seems to derive from their paracrine product, called extracellular vesicles (EVs).

Underwater superoleophobic and transparent (UST) films are promising in applications, such as advanced optical devices in marine environments. However, the mechanical robustness and durability in harsh environments of the existing UST films are still unsatisfactory. In this work, we present a free-standing nacre-inspired mineralized UST (NIM-UST) film with high aragonite content and excellent mechanical properties toward robust underwater superoleophobicity on two surfaces and transparency (94%) in harsh seawater environments.

Background/purpose: Various pulp-covering materials offer advantages in regenerative root canal treatment, but each has limitations, highlighting the need for more effective antibacterial strategies for pulp repair and regeneration. Mesoporous bioactive glasses (MBG) show significant biological activity, making them valuable in tissue/dental repair. Silver-incorporated MBG exhibits promising antibacterial effects against various bacteria; copper ions are crucial in regulating angiogenesis signals.
