Fig. 1From: Pro-inflammatory adjuvant properties of pigment-grade titanium dioxide particles are augmented by a genotype that potentiates interleukin 1β processingTransmission electron microscopy image of TiO2 particles. Food- and pharmaceutical-grade anatase TiO2 particles were suspended in distilled water with 0.5% BSA at a concentration of 1 mg/mL. The particle suspension was analysed with transmission electron microscopy at 80 kV. A representative image is shown; scale bar = 200 nmBack to article page
