Table 3. T₁ values of Au nanoparticles, Fe₃O₄ magnetic nanoparticles and mixture of Au and Fe₃O₄ magnetic nanoparticles (aqueous solutions) with and without light irradiation.

T₁ (s)	Au nanoparticle		Magnetic nanoparticle		Magnetic nanoparticle + Au nanoparticle
Light	Off	On	Off	On	Off	On
Average	2.447	2.453	0.282	0.280	0.284	0.299
SEM	0.067	0.088	0.014	0.010	0.018	0.011
P-value	0.469		0.247		0.448

The data are presented as the mean ± SEM from 10 measurements. The P-value is based on single-trail paired t-test calculation.
