Electron microscopy of nanotubes and diesel particles. Electron microscopic image at 100,000 times magnification (950 × 950 nm) from SWNT, MWNT and diesel (SRM 2975) particle dispersions prepared in distilled water at a concentration of 0.02 mg/ml without stabilizer (PBS) or with addition of mouse serum (+Serum) or human serum albumin (+HSA) before giving concentrated PBS to the dispersion.
