Size distribution of the DNA-AuNP cluster conjugates, its linear relationship and logarithm of DNA concentration. (A) The size distribution of the DNA-AuNP cluster conjugates in aqueous media was obtained by DLS. The concentration of DTT is 800 μM; from left to right, the concentration of DNA is 5 μM, 1 μM, 100 nM, 10 nM, and 2 nM. (B) The linear relationship between the DNA-AuNP cluster conjugates with different average diameters and the logarithm of DNA concentration.
