چکیده

Diabetes is one of the most severe health diseases in world. More than 150 million people worldwide suffer from diabetes caused by an abnormal glucose concentration their blood and tissues. The analysis levels body significant, primarily due to mellitus. Therefore, accurately detecting crucial for diagnosing, treating, managing diabetes. Diabetic patients can self-manage condition monitoring levels. electrochemical biosensor has several advantages, including recognizing specifically, low price, ease sensor manufacture, correctness, portability, easy operation. We have developed glassy carbon electrodes (GCE) with conventional carbon-micro-electromechanical (C-MEMS) procedures sensing. SU-8 photoresist was used as precursor. fabricated C-MEMS-derived GCE surface been functionalized chitosan oxidase. Glucose oxidase a well-known enzyme oxidizing into gluconic acid H 2 O . This reaction kinetics recorded increasing using analysis. In summary, we presented single-step immobilization protocol on electrode obtained satisfactory responses 1 mM 10 solutions.

Fabrication and Characterization of Glassy Carbon MEMS

This paper describes the fabrication of free-standing high-carbon microstructures by softlithographic techniques; these structures ranged in complexity from simple beams to complex, suspended deflectors. Microstructures of polymeric precursors (copolymers of furfuryl alcohol-phenol) to high-carbon solids were fabricated using poly(dimethylsiloxane) (PDMS) molds. Carbonization of these microstru...

Amperometric glucose sensor based on glucose oxidase immobilized on gelatin-multiwalled carbon nanotube modified glassy carbon electrode.

We investigated the direct electrochemistry of glucose oxidase (GOx) at gelatin-multiwalled carbon nanotube (GCNT) modified glassy carbon electrode (GCE). GOx was covalently immobilized onto GCNT modified GCE through the well known glutaraldehyde (GAD) chemistry. The immobilized GOx showed a pair of well-defined reversible redox peaks with a formal potential (E(0)') of -0.40V and a peak to peak...

Electrochemical Sensor for Determination of Fenitrothion at Multi-wall Carbon Nanotubes Modified Glassy Carbon Electrode

A sensor, based on multi-wall carbon nanotubes modified glassy carbon electrode (MWCNT/GCE), was developed for determination of fenitrothion. Determining the surface area of MWCNT/GCE showed that this surface is three times more active than that of a glassy carbon electrode. The experimental parameters, such as the amount of MWCNTs, pH of the fenitrothion solution, preconcentration potential an...
