Particulate matter air pollution and cardiovascular disease: An update to the scientific statement from the American Heart Association. 3rd., Brook J.R., Bhatnagar A., Diez-Roux A.V., Holguin F., Hong Y., Luepker R.V., Mittleman M.A., Peters A., Siscovick D., Smith S.C. Nanomaterial characterization: considerations and needs for hazard assessment and safety evaluation. Carcinogenic hazards from inhaled carbon black, titanium dioxide, and talc not containing asbestos or asbestiform fibers: recent evaluations by an IARC Monographs Working Group. Nanotoxicology and nanoparticle safety in biomedical designs. The methods established in this study could disperse carbon black into ultrafine and fine particles, and may serve as a useful model for the study of particle toxicity, particularly size-related effects.īiocompatible media Carbon black Carbonaceous core Fine particles Particle dispersion Ultrafine particles.Īi J., Biazar E., Jafarpour M., Montazeri M., Majdi A., Aminifard S., Zafari M., Akbari H.R., Rad H.G. Electron microscopy confirmed the typical aciniform structure of the carbon arrays however, zeta potential measurement failed to explain the dispersibility of carbon black. In contrast, 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) exhibited little effect. Application of Tween 80 along with sonication reduced the size of N330 to less than 100 nm, and dispersed N990 larger than 100 nm (73.6 ± 28.8 and 80.1 ± 30.0 nm for N330 and 349.5 ± 161.8 and 399.8 ± 181.1 nm for N990 in KR and PSS, respectively). However, sonication was not enough to disperse N330 less than 100 nm in either KR or PSS. Large clumps were observed in all dispersion preparations however, sonication improved dispersion - averaged particle sizes for N330 and N990 were 85.0 ± 42.9 and 112.4 ± 67.9 nm, respectively, in plasma the corresponding sizes in culture media were 84.8 ± 38.4 and 164.1 ± 77.8 nm. ![]() Carbon black with a distinct particle size, N330 and N990 were suspended in blood plasma, cell culture media, Krebs-Ringer's solution (KR), or physiological salt solution (PSS). Here, biocompatible methods were established to disperse carbon black into ultrafine and fine particles which are generally distinguished by the small size of 100 nm. Carbon black has been used as a surrogate to investigate the biological effects of carbonaceous particles. Dispersion in the aqueous phase has been both a critical impediment to and a prerequisite for particle studies. The biological activity of particles is largely dependent on their size in biological systems.
