Influences of magnetic fields on current–voltage characteristics of gold-DNA-gold structure with variable gaps

Magnetic Field-Dependent Electric Current on a Periodic Poly(da)-Poly(dt) Dna Molecule Structure

“…Experimentally, it has been shown that the magnetic field in DNA molecule causes the electric current decreases at a stronger magnetic field [19]. Besides that, the transport property of the G4 DNA molecule can be tuned by tuning the magnetic field and temperature [22]. Therefore, this report is the result of theoretical research on the magnetic field effect on charge transport behavior on a periodic poly(dA)-poly(dT) DNA.…”

Perubahan Panjang Lokalisasi dan Kerapatan Keadaan Elektron pada Molekul DNA Poli(dA)-Poli(dT) Karena Medan Magnet

“…Sistem sensor dan pensinyalan pada molekul DNA (Sontz et al 2012;Genereux et al 2010) mungkin melibatkan kemampuan DNA untuk mengalirkan muatan listrik dari satu tempat ke tempat lain sebagai pembawa pesan. Belum lama ini, Khatir dkk melaporkan bahwa potensi untuk mengubah sifat transport salah satu molekul DNA (DNA G4) dengan menerapkan medan magnet dan mengubah temperatur (Khatir et al 2015). Karena itu, kami memutuskan untuk mempelajari pengaruh temperatur dan medan magnet pada molekul DNA periodik poli(dA)-poli(dT).…”

Investigating magnetoresistance properties on a periodic poly(dA)-poly(dT) DNA structure

“…A group reports electric current on DNA molecules decreases with the magnetic field [18]. Another group reports the possibility of changing the magnetic field and temperature for tuning the G4 DNA molecule transport behavior [21]. Along this line, this report will focus on theoretical research on the charge transport behavior by considering the magnetic field role, especially the magnetoresistance of a structure of poly(dA)-poly(dT) DNA molecule with a length of 160 bps.…”
