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

Single-walled carbon nanotubes (SWCNTs) show strong fluorescence in the 1000-1700 nm second near-infrared (NIR-II) wavelength range and are considered promising candidates for angiographic imaging probes. Oxygen-doped SWCNTs coated with phospholipid-polyethylene glycol (o-SWCNT-PEG) show exceptional potential, as they emit fluorescence at

Single-walled carbon nanotubes (SWCNTs) have unique photophysical properties and serve as building blocks for biosensors, functional materials and devices. For many applications it is crucial to use chirality-pure SWCNTs, which requires sophisticated processes. Purification procedures such as wrapping by certain
