Molecular Dynamics Simulations of DNA- Covered Carbon Nanotubes

Myrna Merced Serrano*, José O. Sotero Esteva, UPR-Humacao Robert Johnson**, A.T. Johnson, U. of. Pennsylvania * Undergraduate Student (sophomore) ** Graduate Student A FET device made with a single wall carbon nanotube (SWCNT) decorated with single-strand DNA (ss-DNA) has shown potential for use as a gas sensor. Using Molecular Dynamics simulation to study the interaction between ss-DNA and SWCNTs. Studying the way in which the ss-DNA adsorbs onto a SWCNT as a function of the length of the strand (Click on Nanotube to see animation).
