Fig. 2From: Enzyme adsorption-induced activity changes: a quantitative study on TiO2 model agglomerates a, b Scanning electron micrographs of β-gal/TiO2 heteroaggregates. c Number-weighted size distribution of β-gal/TiO2 heteroaggregates as determined from the electron micrographs (a, b) and of TiO2 agglomerates as determined by DLS. Samples for SEM analysis were prepared from dispersions previously analyzed by DLS (Fig. 1)Back to article page
