Nanoparticles, defined by their nanoscale dimensions and unique physicochemical properties, are widely utilized in healthcare, electronics, environmental sciences, consumer products. However, increasing evidence of potential embryotoxic effects during pregnancy underscores the need for a molecular-level understanding interactions embryonic development. Nanoparticles such as titanium dioxide, silver, cerium oxide, copper quantum dots can cross placental barrier interfere with crucial developmental processes. At molecular level, they disrupt signaling pathways like Wnt Hedgehog, induce oxidative stress inflammation, cause genotoxic effects, all critical sensitive phases, organogenesis. Furthermore, these nanoparticles interact directly cellular components, including DNA, proteins, lipids, impairing function viability. Innovative strategies to mitigate nanoparticle toxicity, surface modifications incorporation biocompatible coatings, discussed solutions reduce adverse interactions. Various laboratory animal models used investigate nanoparticle-induced embryotoxicity evaluated efficacy limitations, providing insights into applicability effects. This Account examines mechanisms which compromise development emphasizes importance designing safer minimize maternal-fetal exposure risks, particularly biomedical applications.

Abstract Hydrogen sulfide (H 2 S) contamination of food has raised widespread public health concerns, leading to substantial medical and economic burdens. Herein, a 2D/0D heterojunction fluorescent probe (TCTG) with Schottky barriers (SB) is designed synthesized, utilizing Ti 3 C T x MXene‐loaded graphene quantum dots (GQDs), for the detection H S during spoilage. The microstructures observed through SEM TEM reveal that uniformly sized GQDs are evenly attached surface monolayer . chemisorption between facilitates charge transfer formation SB, resulting in intramolecular (ICT) effects. With introduction S, TCTG (50%) exhibits highest sensitivity, selectivity, anti‐interference properties, ultra‐fast fluorescence transient reaction (3s) remarkably low limit 41.82 ppb as well noticeable color change. When reacted ICT effects inhibited, recovery photoinduced electron (PET) quenching. Notably, effectively utilized detect changes levels raw foods assess their quality. Overall, significance this study its potential revolutionize spoilage detection, offering fast, reliable, sensitive method ensure safety reduce associated
