Abstract

Selective detection of biological pathogens is of great importance in health care. Early detection of infections can help isolate diseases at earlier stages and therefore facilitates early containment and eradication. Fluorescent DNA microarrays have been used extensively to detect pathogens with specific gene expressions. Recently, gate-modified transistors (BioFETs) have been used for direct electrical detection of DNA hybridization. This paper addresses a model that describes the electrical response of the BioFET to charged DNA strands, and provides some insight on the noise characteristics as limiting factors for the sensitivity of such sensors.
