Electrochemical Detection in Microfluidic Devices
نویسنده
چکیده
Screen-printing was used to incorporate electrodes into a channel of a microfluidic device. These enabled, through the electrochemical oxidation of hydrogen peroxide, the determination of glucose which had been added to milk pre-treated by ultrafiltration. Screen-printing is a relatively simple, inexpensive technique and its use to add electrochemical detection to microfluidic devices is a step towards convenient chemical analysis at point of need.

متن کاملRecent Developments in Optical Detection Technologies in Lab-on-a-Chip Devices for Biosensing Applications
The field of microfluidics has yet to develop practical devices that provide real clinical value. One of the main reasons for this is the difficulty in realizing low-cost, sensitive, reproducible, and portable analyte detection microfluidic systems. Previous research has addressed two main approaches for the detection technologies in lab-on-a-chip devices: (a) study of the compatibility of conv...
