(wt-%)
Carbon black   141 ± 0.9(1) 270(3) 0.032(5)
Asbestos 2.8 ± 2.6 (1)(2) 116 ± 112(1)(2) 9.1(2) 22.2(2)
MWCNT 1 6.1 ± 2.5(1) 163 ± 49(1) 10(3) < 0.1(5)

  1. (1) Size distribution in serum-free medium was evaluated by SEM and TEM using NIH Image J software. Mean ± SD. Particle size distribution of carbon black was evaluated by DLS.
  2. (2) As reported in Moalli et al., 1987 [31] and in Guo et al., 2007 [37].
  3. (3) Determined by nitrogen vapor adsorption using BET theory.
  4. (4) As reported in Poland et al., 2008 [35].
  5. (5) Determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES).
