In-situ synthesis of silver nanoparticles on resin microspheres composed of poly(m-aminophenol), and their application in an enzymatic glucose biosensor

Glucose oxidase stabilized fluorescent gold nanoparticles as an ideal sensor matrix for dual mode sensing of glucose

“…Typical sensor characteristics in terms of sensitivity, detection limit and Michaelis-Menten rate constant values obtained in this work using both electrochemical and colourimetric methods are compared with various other enzyme based materials reported in literature as shown in Table 1. 28,29,36,[44][45][46][47][48][49][50][51][52][53][54][55][56] It can be seen from the table that GOx-FL Au NPs exhibit a higher sensitivity, lower detection limit and apparently lower K M values for electrochemical detection of glucose when compared to many other electrode materials reported for enzymatic detection of glucose. Similarly in the case of colourimetric detection method using ABTS bio-assay GOx stabilized FL Au NPs display a lower detection limit compared to other materials.…”

The simultaneous detection of the squamous cell carcinoma antigen and cancer antigen 125 in the cervical cancer serum using nano-Ag polydopamine nanospheres in an SERS-based lateral flow immunoassay

“…Aer the immobilization of Ag nanoparticles, a peak appeared near 475 nm due to the surface plasmon resonance of the Ag nanoparticles. 43,44 The blue shi in this peak from 475 nm to 438 nm and 440 nm demonstrates that the Raman reporters and antibodies were modied successfully on the PDA@Ag-NPs. 45,46 Fig.…”

Recent Advances in Applications of Oxidases and Peroxidases Polymer-Based Enzyme Biocatalysts in Sensing and Wastewater Treatment: A Review

“…Glucose is one of the primary energy sources for plants and animals [ 343 ]. In humans, it is found in the blood stream and its levels are related to diabetes mellitus, which is a significant threat to human health [ 344 ].…”
