Arginine (Arg) is involved in tissue metabolism and regulates the immune function; thereby, achieving detection of Arg crucial for early diagnosis treatment diseases. Herein, dual ratiometric fluorescence sensors were prepared with blue emission levorotatory/dextrorotatory carbon dots (CDs) red porphyrin (L/D-CDs-PP) sensitive portable Arg. Interestingly, L-CDs-PP D-CDs-PP displayed not only peaks at 493 650 nm but also different response modes to Arg; thus, they could serve as achieve accurate reliable Arg, limit 23.87 μM 2.39 D-CDs-PP. Importantly, solid-state successfully achieved dual-mode visual support a smartphone platform. In addition, exhibited excellent biocompatibility cell imaging capabilities, cells biological samples urine rat plasma. Therefore, broad application prospects fields analytical sensing, imaging, medical diagnosis.

Monitoring and controlling antibiotic residues in the environment are critical for minimizing bacterial resistance, preserving microecological equilibrium, protecting human health. Core competencies of sensor include sensitivity, selectivity, mobility. It is still very difficult to combine these qualities a single effective tetracycline (TC) detection. Herein, flower-like spherical structure high-entropy layered double hydroxide Fe0.45Co0.45Ni0.45Cu0.45Zn0.45-LDH (HE-LDH) was prepared with superior peroxide-like activity convert hydrogen peroxide (H2O2) hydroxyl radicals (•OH) (Km = 0.075 mM H2O2). Because significant reactivity that exists between TC •OH produced catalytic system, simple colorimetric method detection established. As performance, linear range limit were 100–1000 25.6 nM solution mode, respectively. Also, 100–800 32.2 obtained paper mode. The developed also exhibited good selectivity over other antibiotics, amino acids, ions. Furthermore, use actual water sample analysis demonstrated excellent self-calibration satisfactory recovery 95.4–103.1%. This study offers progress toward developing nanozymes enzyme-like detection, accelerating development efficient portable sensors.
