Nanozymes play a pivotal role in mitigating excessive oxidative stress, however, determining their specific enzyme-mimicking activities for intracellular free radical scavenging is challenging due to endo-lysosomal entrapment. In this study, we employ genetic engineering strategy generate ionizable ferritin nanocages (iFTn), enabling escape from endo-lysosomes and entry into the cytoplasm. Specifically, repeated Histidine-Histidine-Glutamic acid (9H2E) sequences are genetically incorporated...

Addressing heavy metal contamination in water bodies is a critical concern for environmental scientists. Traditional detection methods are often complex and costly. Recent advancements artificial intelligence (AI), particularly machine learning (ML) deep (DL), have shown significant potential analytical chemistry. However, these AI models require extensive spectral data, which traditional struggle to provide quickly. To overcome this challenge, we developed new digital imaging system rapidly...

Abstract Chlorella vulgaris ( C. ) and Raphidocelis subcapitata R. are two model algal species applied for the testing of chemicals, whereas a considerable variation in their sensitivity to antibiotics has been reported. The difference may be attributed xenobiotic‐induced oxidative stress cells. Thus, this study compared responses these green algae toward exposure erythromycin (ERY), macrolide antibiotic, at concentration levels 0, 20, 40, 60 μg/L, elucidated toxic mechanism action from...
