An electrical field sensor for micro/nano particles detection applications

This paper presents an electrical field sensor, which can be used in both biomedical applications and cell characterization. The Lab-on-Chip contains two main parts: 1) A CMOS Lab-on-Chip integrated Circuit (IC) which is based on 0.18 µm technology and includes the sensing and actuation parts, 2) a printed circuit board which contains the amplifications and conditioning parts. Experimental result shows that the automated Lab-on-Chip is a good candidate for biomedical applications, such as in the DNA analysis, to detect the radius of the DNA molecule, and in cancer research area, to help in selecting the suitable antibody for cancer treatment.
