- an aggregate is a collection of particles strongly linked or fused having a outer surface area may be significantly smaller than the sum of all surface areas of each component.
- an agglomeration is a collection of particles weakly linked, of aggregates or a mixture of both having a outer surface area which is similar to the sum of all surface areas of each component.

Definitions
Nano-objects (particles, fibers, plates, tubes,...) are entities with at least one dimension is smaller than 100 nanometers. These entities are the basis for the formation of nano-structured materials on the surface or in volume. They are passive or active as nanodevices. This website deals the risks associated with nanomaterials without covering the wider field of nanotechnologies.
