(from left to right) TEM image of CuS PNPs. The diameter of the spheroids was 11 ± 3 nm (see inset). LSPR band of these PNPs dispersed in water. The extinction of pure water is displayed for comparison. The dashed line indicates the excitation wavelength for PAI. Image of a mouse brain where CuS PNPs were injected into a nodule. The image of the nodule is highlighted by an arrow. Adapted with permission from Ref. [152]. Copyright 2012 American Chemical Society.
