Table 1 Surface chemistry, hydrodynamic diameter, and surface charge density of unmodified- (UNP), carboxyl-modified (CNP) and amine-modified (ANP) latex nanoparticles in distilled water (DW) and tissue culture medium (DCCM1 and RPMI)

From: Differential bioreactivity of neutral, cationic and anionic polystyrene nanoparticles with cells from the human alveolar compartment: robust response of alveolar type 1 epithelial cells

Particles Surface functional group Average diameter nm(±SD) Polydispersity index Zeta potential mv(±SD)
  1. The data are presented as mean ± standard deviation (SD), n = 3β
  2. βNanoparticles were suspended in distilled water and DCCM1 or RPMI at a concentration of 10 μg/ml and bath sonicated for 2 min before measurement (see methods)
