Turyanska, Lyudmila and Moro, Fabrizio and Knott, Andrew N. and Fay, Michael W. and Bradshaw, Tracey D. and Patanè, Amalia (2013) Paramagnetic, near-infrared fluorescent Mn-doped PbS colloidal nanocrystals. Particle & Particle Systems Characterization, 30 (11). pp. 945-949. ISSN 0934-0866
Mn-doped PbS colloidal nanocrystals in aqueous solution are paramagnetic and optically active in the technologically important biological window between 1.2 and 0.8 μm. Cytoxicity studies show that exposure of human cell lines to the nanoparticles at concentrations up to 0.2 mg mL−1 does not induce any adverse effect.
