Design, modeling and performance analysis of carbon nanotube with DNA strands as biosensor for prostate cancer

Technical Paper

Abstract

Prostate cancer which causes panic among human beings due to deaths occurring when not detected in initial stages demands a means of detection and diagnosis. Biosensors play an important role in detection of cancer cells or molecules in blood samples or urine samples using DNA strands. In this paper, we analyze properties of Single Wall Carbon Nano Tube (SWCNT) and Multi Wall Carbon Nano Tube (MWCNT) of 30 nm length and semiconducting nature. SWCNT is suitable for biosensor applications due to its high current carrying capability. Prostate Specific Antigen present in blood sample is detected using DNA strands, in this work three different DNA strands are analyzed for its performance. Surface charge density is 23.4656 M for dsDNA strand. The simulation tool Monte Carlo from Nanohub.org is used for validation of results.
