Abstract
Methods for controllably creating agglomerates from particles of colloidal dimensions. Creation of agglomerates permits physical isolation or separation of, e.g., unwanted cell debris from cleared cell lysate comprising target particles, by the deposition or creation of a blocking or masking layer. Chaotropic agents are utilized to enhance colloidal particle agglomeration. The resulting agglomerant or 'floc' can be deposited, as needed, in a separation/isolation process to create a blocking or masking layer on an 'as needed' basis.
