Chiral-Induced Spin Selectivity Modulated Time-Correlated Single-Photon Counting for DNA Hybridization Detection

Neeraj Bangruwa,
Mayank Tiwari,
Ankur Shandilya
et al.

Abstract: The chiral-induced spin selectivity (CISS) effect can distinguish between the spin of electrons as they pass through chiral molecules by backscattering one of the spin components. Herein, we explore the role of the CISS effect in time-correlated single-photon counting measurements to detect DNA hybridization. We observe that the average lifetime of optical excited states of quantum dots attached to doublestranded DNA (dsDNA) varies with directions of the applied magnetic field. Specifically, the difference in … Show more

“…Peak number 1 observed at around 1070 cm −1 for the CFA/ss-DNA/QD and CFA/ds-DNA/QD devices represents the CO stretching. 10,25 Peaks observed at around 1114 cm −1 and 1270 cm −1 (marked as 2) both represent the asymmetric and symmetric groups belonging to the phosphodiester backbone (PO 4 − group). 10,25 The C4C5 vibrations at 1470 cm −1 are represented by peak 3.…”
