Fig. 1From: Enzyme adsorption-induced activity changes: a quantitative study on TiO2 model agglomeratesParticle size distribution as related to β-gal, TiO2 agglomerates and mixtures of β-gal and TiO2 agglomerates in aqueous suspension. A size increment from ~80 to ~140 nm reveals the adsorption of β-gal and the formation of β-gal/TiO2 composites. [β-gal] = 50 µg mL−1; [TiO2] = 0.1 mg mL−1 Back to article page
