What is it about?
The work shows that the sequence of DNA controls the spin selectivity for the first time experimentally. If there is a modification in the structure of a double-strand DNA, then the net spin carried by electrons changes accordingly. Lifetime decay study with theoretical investigation using the tight binding approach was adopted to conclude the results.

Why is it important?
The work is very important as it uses the spin of electrons to probe the change in sequence of a double-strand DNA. Our work confirms an earlier theoretical prediction of sequence-specific spin control in DNA molecules.
Perspectives
Our findings could pave the way for next-generation spin-based DNA sensors.
