Table S2.

Form factor parameters obtained from the fits to the SANS measurements using the form factor model given in Particle Form Factor

Sample	Protonated	${\zeta }^{\mathbf{e}\mathbf{f}\mathbf{f}}$	R, nm	$R_{\mathbf{c}}$, nm	σ, nm	${\sigma }_{\mathbf{p}}$, %	ξ, nm
cm1	Large ($2.9\pm 0.3$%)	$2.17\pm 0.04$	113 $\pm$ 2	84 $\pm$ 1	$14.4\pm 0.5$	11 $\pm$ 3	$7.2\pm 0.5$
cm2	Small ($16\pm 3$%)	$2.14\pm 0.03$	95 $\pm$ 5	83 $\pm$ 2	$6\pm 1.5$	10 $\pm$ 2	11 $\pm$ 3

Here, cm1 and cm2 are the samples that show the maximum deswelling. The errors of the parameters have been obtained form the data fit. We also report the percentages of protonated particles and ${\zeta }^{\text{eff}}$.
