Electric Double Layer Simulation on Transient State for Sensitivity Enhancement of Affinity-Based Biosensor

Woo J-M, Kim S-H, Park Y.J., Seoul National University, KR

We have presented a numerical simulation for the affinity-based electrical biosensor system on the steady and transient state. Considering the screening length in the solutions, the solution with low ion concentration can be better measurement [...]

A Fully Electric DNA Detection using CMOS integrated CNT network Sensor

Kim S-H, Woo J-M, Ahn J.H., Park Y.J., Seoul National University, KR

A fully CMOS integrated carbon nanotube (CNT) sensor platform that consists of 32X32 array of unitary CNT elements for electric bio material detection is presented. For digital conversion of the analog voltage of CNT sensor [...]

The acid-base properties of carboxylated CNT and the design of CNTFET biosensor

Kwon H.J., Woo J-M, Lim J., Kim S-H, Park Y.J., Seoul National University, KR

We observed the sign of the two responses from carbon nanotube field effect transistor (CNTFET) in aqueous solution by means of dynamic measurements. Two types of surface group, the hydroxyl and the carboxyl group of [...]
