The magnetic forces contribute to attractive forces among the nanoparticles and that leads to increasing of aggregation of the nanoparticles.
With non-functionalized graphene sheets, the degree of dispersion decreased as the graphene loading increased because of an increased probability of aggregation, whereas the functionalized graphene sheets did not tend to aggregate, even at high loadings.
Usually, increasing the hydrophobic domains means an increasing degree of aggregation.
We found that the degree of dispersion decreased with the increasing loading of graphene sheets because of the increased probability of aggregation at higher loadings; however, functionalized graphene sheets did not exhibit aggregation.
An increase of platelet aggregation was observed in dogs receiving immunosuppressive doses of prednisone (Group II).
The increase of cell aggregation of WT cells in the presence of IPTG was independent of cell growth rate.
A significant increase of platelet aggregation was observed only in the group treated with the immunosuppressive dose of prednisone.
The increase of tau aggregation in the brain of P301S mice which had been intraperitoneally injected with taumu indicated a centrifugal spread of tau aggregates or aggregation.
Moreover, the change in the ionic composition of erythrocytes entails deterioration in their deformability and the increase of the aggregation capacity [ 18, 19].
