An aggregate for qualitatively or quantitatively determining bindable substances. Said aggregate comprises an ultra small colloidal particle and a specific binding agent characterized in that the mean diameter of the colloidal particle is below 2 nm. Preferably the size of the metal particle is selected so that the aggregate is capable of penetrating in standard biological specimens. A universally applicable detection system for determining bindable substances in particular in living material. Further there is provided a process for preparing said aggregate.
