The interaction of SiO2 including carbon nanoparticles (CNPs) with human serum albumin (HSA) in vitro under simulated physiological conditions has been studied by fluorescence methods and dynamic light scattering (DLS). Experimental results indicated that SiO2 including CNPs can be stabilized in the physiological environment and emit fluorescence, which quench HSA fluorescence by a static quenching mechanism. Our findings indicate that understanding the interaction between proteins and carbon nanoparticles is crucial for toxicological studies.

Nanoscale carbon particles have emerged as versatile precursors for a new class of highly fluorescent nanomaterials that resemble semiconductor quantum dots. The surface-passivated fluorescent carbon nanoparticles, dubbed ‘carbon dots’, were already demonstrated for their potential optical bioimaging applications in vitro and in vivo. In this study, we conducted a systematic cytotoxicity evaluation on the carbon dots prepared by various combinations of precursor carbon nanoparticles and molecules for the particle surface functionalization. The results suggested that the cytotoxicity of carbon dots was dependent on the selection of surface passivation molecules. Those dots showing more significant cytotoxicity at higher concentrations were also evaluated for their effects on the fluorescence imaging of live cells. The implications of the results on the eventual use of carbon dots as cell imaging agents are discussed.
