复杂的(生物)样品在近红外(NIR)中的成像是有益的，因为它减少了光散射、吸收、光毒性和自发荧光。然而，目前已知的适合于生物医学应用的近红外荧光材料还很少。在这里，我们通过球磨和简单的尖端超声将层状颜料CaCuSi4O10(埃及蓝，EB)剥离成近红外荧光纳米片(EB-NS)。EB-NS的大小可以根据直径进行定制
Imaging of complex (biological) samples in the near-infrared (NIR) is beneficial due to reduced light scattering, absorption, phototoxicity, and autofluorescence. However, there are few NIR fluorescent materials known and suitable for biomedical applications. Here we exfoliate the layered pigment CaCuSi4O10 (Egyptian Blue, EB) via ball milling and facile tip sonication into NIR fluorescent nanosheets (EB-NS). The size of EB-NS can be tailored to diameters
