Calculated radius of gyration (R_g) of ssDNA using the equation, ${\text{R}}_{\text{g}}=\sqrt{\sigma L/3}$, where σ is the persistence length (5 nm) [55] of the ssDNA and L is the contour length [L = number of nucleotides × length per (0.43 nm)]

	Radius of gyration (Rg)/nm
Oligo 35	5.0
Oligo 50	5.9
Oligo 70	7.1
