In this study, a laser‐induced graphene (LIG) loaded platinum nanoparticles (PtNPs) was prepared for precise, rapid and non‐enzymatic electrochemical detection of hydrogen peroxide (H2O2). The commercial PI films were used as the substrate of LIG. In order to improve the electrochemical performance of LIG, a layer of PtNPs catalyst was fabricated through a magnetron sputtering process on the surface of LIG (PtLIG). Under optimized conditions, a linear relationship between H2O2 reduction current and H2O2 concentration was recorded, the correlation coefficient R2 is 0.9919 with the detection limit of 0.1 μM (S/N=3) and the sensitivity of 248.4 μA mM−1cm−2. Moreover, the PtLIG exhibits excellent selectivity, reproducibility and repeatability. Because of these remarkable advantages, we believe that PtLIG will provide a wider range of applications in biosensors and bioelectronic devices.

“…Hydrogen peroxide is considered to be a significant mediator in food, clinical, industrial, pharmaceutical, and environmental analyses [4]. Many analytical techniques were widely utilized for the detection of hydrogen peroxide such as electrochemical [5][6][7][8][9][10][11][12][13][14], titrimetry [15], fluorescence [16,17], and colorimetric [18][19][20][21][22][23][24][25][26]. In comparison with other reported methods, there are considerable advantages of colorimetric detection of various analytes over other conventional sensing techniques e.g., costeffectiveness, facile and reliable method, and practicability and quick response.…”

Nanomaterials based colorimetric detection is an area of vital importance in the field of sensing applications. The nanoparticles are the main component of colorimetric sensor in replacing the natural enzyme based sensor. In this context, zero valent nanoparticles have revolutionized the field of optical sensing especially due to easily shift of electron, facile and low cost of preparation, and ease of surface modification. In this work, zero valent manganese nanoparticles (ZV-Mn NPs) are prepared through a simple and very quick method and modulated with new type of ionic liquid (IL). Asprepared materials were characterized through FE-SEM, HR-TEM, BET, FTIR, and XRD. Subsequently, the peroxidase like catalytic activity of pure and modified ZV-Mn NPs to catalyze oxidation of N,N′,N,N′-tetramethylbenzidine (TMB) in the presence of hydrogen peroxide (H 2 O 2 ) investigated. Moreover, the absorbance peak is observed at wavelength 652 nm. The enhanced catalytic activity of ZV-Mn NPs was attributed to the fast transfer of electron mechanism in between substrate and H 2 O 2 . The coating of IL on ZV-Mn NPs permitted a low limit of detection 0.2 μM with a linear range of 10-280 μM. This work can find wide spread interest in the colorimetric sensing applications. In order to verify the successful demonstration of H 2 O 2 sensor, we have applied it in the dairy milk products with satisfactory results.

“…However, the complexion process limits their further applications. Later, an one-3 pot method through simultaneous reduction of GO and Ag salt by the same reducing agent has been developed, where several kinds of chemicals have been used as reducing agents, such as tannic acid [10], ionic liquid [11], diethylenetriamine [12], Azadirachta indica extract [13]. Unfortunately, the presence of organic molecules in the final samples could block the electrons transmission rate, leading to poor performances for various applications.…”
