A flow-through amperometric sensor for micro-analytical systems

Low temperature co-fired ceramic (LTCC)-based biosensor for continuous glucose monitoring

“…The SR value for the structure made in Perspex ® (SR = 2.4 [15]) was evidently lower than the SR obtained for silicon/glass (SR = 4.9 [14]) and ceramic (SR = 5.4) sensors. This means that effectiveness of the electrochemical and enzymatic conversion of glucose to hydrogen peroxide is better for microsystems made with silicon/glass and LTCC technologies.…”

“…The presented LTCC-based glucose biosensor was based on construction of a similar amperometric sensors made in silicon/glass [14] and Perspex ® [15] materials. In order to make a comparison between all sensor structures a sensitivity rate (SR) was chosen.…”

“…It can easily be applied to amperometric detection of other essential for human health biochemical compounds e.g., lactate, glutamate etc., by use of a relevant enzyme lactate-oxidase, glutamate-oxidase etc. Similar systems made in silicon/glass [14] and polymeric materials [15] were studied previously. The advantages of the LTCC structure, in comparison with the silicon one, are: a much lower price and a shorter development time for a new structure.…”

On-line flow injection analysis using gold particle modified carbon electrode amperometric detection for real-time determination of glucose in immobilized enzyme hydrolysate of waste bamboo chopsticks

“…The standard addition calibration curve of the electrode was prepared by using standard addition method [24] at 35°C. The NaPB was deoxygenated with nitrogen bubbling for 10 min before each measurement.…”

Recent developments in electrochemical flow detections—A review

“…Enzymes were immobilized by physical entrapment on the surface of a photocrosslinkable polymer covering the electrode surface. A silicon glass sandwich with two wafers, a Pyrex glass wafer with a patterned platinum electrode and a silicon wafer with the system of channels, was utilized in producing a microsystem with built-in semipermeable dialysis turning for amperometric deter- mination of glucose [236]. Determinations were carried out with the use of glucose oxidase in the solution and a planar Pt working electrode in the reaction cell made in a glass wafer.…”
