    • Direct current electrical characterization of ds-DNA in nanogap junctions 

      Iqbal, Samir M.; Balasundaram, G.; Bashir, R.; Bergstrom, D. E.; Ghosh, Subhasis (Copyright American Institute of Physics;Department of Electrical Engineering, 2005-04-05)
      Measurements of DNA conductivity, hybridization, and melting using electronic means can have wide applications in molecular electronics and biological sensors. We have fabricated nanogap break-junctions by electromigration ...

    • Electrical detection of single-base DNA mutation using functionalized nanoparticles 

      Iqbal, Samir M.; Christensen, Shawn; Goyal, Swati; Noor, Mohammud R. (Copyright American Physical Society,Department of Electrical Engineering, The University of Texas at Arlington, 2009-08-17)
      We report an electrical scheme to detect specific DNA. Engineered hairpin probe DNA are immobilized on a silicon chip between gold nanoelectrodes. Hybridization of target DNA to the hairpin melts the stem nucleotides. Gold ...

    • A mesoscale model of DNA interaction with functionalized nanopore 

      Iqbal, Samir M.; Liu, Yaling (Copyright American Physical Society,Department of Electrical Engineering, The University of Texas at Arlington, 2009-11-30)
      Functionalized nanopores have been used recently for the detection of specific DNA. The interactions between the DNA and the nanopore are not well understood due to the small size of DNA/nanopore and dynamic translocation ...

    • Microheater platform for selective detachment of DNA 

      Iqbal, Samir M.; Jain, Ankur; Javed, Annas (American Institute of Physics;Department of Electrical Engineering, University of Texas at Arlington, 2012-08-30)
      Despite deoxyribonucleic acid (DNA)’s well-known temperature sensitivity, not much work has been reported on leveraging temperature to manipulate the interaction of DNA with surfaces. This paper describes a microheater ...
