Acute pesticide poisoning has resulted in several symptoms that threaten life safety. Thus, developing a rapid detection method would facilitate the identification of toxicants as soon possible. This study presented an affordable and straightforward platform based on core-shell structure nanocomposite Prussian blue/Fe-metal-organic frameworks/Ce material, which exhibited peroxidase-like activity multiple capture sites [marked phosphate buffer (PB)/Fe-MOF/Ce NPs]. Fe3+ Fe2+ are located at core PB nanoparticles (PB NPs), metal-porphyrin metal-organic framework (MOF) shell, Ce NPs grown shell. A practical, economical, accurate, colorimetric strategy was synthesized to detect organophosphorus pesticides directly fetal bovine serum. The solution-based PB/Fe-MOF/Ce NP sensor demonstrated ultrasensitive performance excellent reproducibility. absorbance variation dichlorvos, methamidophos, dimethoate follows linear equation y = 0.093x + 0.024, 0.083x 0.017, 0.114x 0.117 under low content, limit (LOD) determined using 3s/slope, 5.6, 4.8, 6.5 μg/L, respectively, with recovery rates ranging from 83.4% 98.6% RSD less than 6%. provides for effectively detecting acute samples offers profound insights further improving treatment efficiency poisoning, it prospects clinical point-of-care testing.

Biotemplated Platinum Nanozymes: Synthesis, Catalytic Regulation and Biomedical Applications

ChemBioChem, Год журнала: 2024, Номер unknown

Опубликована: Авг. 22, 2024

Abstract Platinum (Pt) nanozymes with multiple intrinsic enzyme‐mimicking activities have attracted extensive attention in biomedical fields due to their high catalytic activity, ease of modification, and convenient storage. However, the Pt synthesized by traditional method often suffer from uncontrollable morphology poor stability under physicochemical conditions, resulting unsatisfactory behavior practical applications. To optimize ability, biological templates been introduced recently, which can guide deposition platinum ions on surface form specific morphologies then stabilize nanozymes. Given promising potential biotemplated applications, it is essential conduct a systematic comprehensive review summarize recent research progress. In this review, we first categorize discuss mechanisms as well characteristics each type biotemplate directing growth nanozyme. Factors that impact are analyzed, followed summarizing Finally, challenges opportunities field outlined. This article aims provide theoretical guidance for developing robust functionalities
