Amperometric cholesterol biosensor based on the direct electrochemistry of cholesterol oxidase and catalase on a graphene/ionic liquid-modified glassy carbon electrode

Ultrasensitive strategy based on PtPd nanodendrite/nano-flower-like@GO signal amplification for the detection of long non-coding RNA

“…The results indicate that the developed RNA biosensor was excellent and could be used for lncRNA HULC analysis with acceptable reproducibility. Response time is the time required for reaching 95% of the equilibrium signal towards different catalytic material (Choi and Yiu, 2004;Gholivand and Khodadadian, 2014). The biosensor exhibited a rapid response to the changes in 0.8 mM H 2 O 2 concentration in 2 s. But the stable DPV current can be obtained only after 15 s. And the response time of the biosensor was 15 s on going from 0.0 to 0.8 mM H 2 O 2 .…”

A novel paper-based device coupled with a silver nanoparticle-modified boron-doped diamond electrode for cholesterol detection

“…Various analytical strategies for cholesterol assays have been developed that can be subclassified into two groups, including a chemical and an enzymatic method [2][3][4][5]. Currently, the enzymatic method has received greater attention for cholesterol analysis because it provides greater sensitivity and selectivity than the chemical method.…”

An Enzyme Assisted Electrochemical Detection System of Purine Intracellular Utilizing MWCNTs-IL Modified Glassy Carbon Electrode

“…IL, with their high polarity, high selectivity, fast rates, and great biomolecule stability is considered to be suitable media for supporting biocatalytic processes [41,42]. MWCNTs-IL, which combined the advantages of MWCNTs and IL with wide electrochemical window, could ensure that two electrochemical response of cell were detected simultaneously.…”
