The current study aims for a simple, rapid, and smartphone‐based enhanced chemiluminescence (eCL) technique for sensitively detecting glucose in human urine. Herein, 1,3‐propanedithiol cross‐linked gold nanoparticles (GNPs‐PDT) via a simple reduction method is synthesized. Further, it is characterized by UV–vis spectroscopy and transmission electron microscopy. The synthesized GNPs‐PDT is found to possess oxidase mimetic activity and generate superoxide radicals from dissolved oxygen, which causes the oxidation of luminol to give a strong and stable CL signal. On the introduction of glucose into the reaction system, a CL quenching phenomenon is observed owing to the tendency of superoxide radicals to oxidize glucose into gluconic acid. Employing the quenching effect of glucose on the eCL signals, a sensor is designed for glucose detection in human urine samples. Under optimized conditions, the proposed method works in a dynamic range from 0.25 to 2 mM (R 2 = 0.98) with a detection limit of 0.36 mM. In addition, a simple and portable smartphone‐based imaging technique analyzed by Image J software for eCL‐based glucose sensing is proposed. The developed proof of concept provides good correlations of glucose detection in diabetic patients.

Two-dimensional (2D) inorganic layered materials when embedded in organic polymer matrix exhibit exotic properties that are grabbing contemporary attention for various applications. Here, nanosheet morphology of molybdenum disufide (MoS2) synthesized via one-pot facile hydrothermal reaction are exfoliated in benign aqueous medium in the presence of indole to obtain a stable dispersion. These exfoliated nanosheets then act as host to template the controlled polymerization of indole. The preassembled MoS2-polyindole (MoS2-PIn) nanostructures are reorganized at the air-water interface using the Langmuir method to facilitate maximum interfacial interaction between nanosheet and polymer. This report emphasizes large area, homogeneous dispersion of uniform-sized MoS2 nanosheets (40-60 nm diameter) in the PIn matrix and the formation of stable and uniform film via the Langmuir-Schaefer (LS) method. These self-assembled, MoS2 decorated PIn LS films are characterized using atomic force microscopy (AFM) and transmission electron microscopy (TEM). The fabricated LS films in sandwiched structure Al/MoS2-PIn/ITO as the Schottky diode portrayed remarkable enhancements in charge transport properties. Our study illustrates the potential of the MoS2-PIn LS film in electronic applications and opens a new dimension for uniform dispersion of 2D materials in other polymers via the Langmuir method for device fabrication and enhancement of electrical properties.
