Biosensors fabrication

In view of the future development of sensors driven by increasing demand for accuracy and precision, and by the opening of new fields close to the biological area (which is oriented toward nano-biosensor fabrication), it appears even more important to properly use the most relevant sensor keywords, such as response curve, sensitivity, noise, drift, resolution, and selectivity. 

Biosensors fabricated on the Nafion and polyion-modified palladium strips are reported by C.-J. Yuan [193], They found that Nafion membrane is capable of eliminating the electrochemical interferences of oxidative species (ascorbic acid and uric acid) on the enzyme electrode. Furthermore, it can restricting the oxidized anionic interferent to adhere on its surface, thereby the fouling of the electrode was avoided. Notably, the stability of the proposed PVA-SbQ/GOD planar electrode is superior to the most commercially available membrane-covered electrodes which have a use life of about ten days only. Compared to the conventional three-dimensional electrodes the proposed planar electrode exhibits a similar... 

An SPCE modified with CoPC was employed as an H202 transducer in a cholesterol biosensor fabricated by the drop-coating of ChOx, followed by a cellulose acetate membrane [50]. The resulting cholesterol biosensors were operated in stirred solutions using an applied potential of +400 mV vs. screen-printed Ag/AgCl, and displayed a linear range of 0.06-5 mM.

However, the application of cobalt- oxide nanomaterials for immobilization of biomolecelus and biosensor fabrication is rare. Recently we used electrodeposited cobalt-oxide nanoparticles for immobilization of hemoglobin [67], The UV-visible spectrophotometric analysis and voltammetric studied indicates the immobilization of Hb onto cobalt-oxide nanoparticles (Figure 35).
