An aspect of embodiments of the invention relates to surface modified proteinaceous spherical particles (SMOP). SMOPs according to an embodiment of the invention may comprise a protein layer and an amyloid-binding moiety bound to the protein. In an embodiment, the protein layer is spherical in shape and comprises proteins linked to each other by disulfide bonds. It is suggested that SMOPs are effective in preventing formation of amyloid and aggregation of Aβ when administered to a patient in need thereof.
