Detection of Femtomolar Proteins by Non-Fluorescent ZnS Nanocrystal Clusters

Cation exchange (CX) in the non-fluorescent ZnS nanocrystal clusters (NCCs) was employed to detect trace biomolecules with immunoassays. The NCCs were porous, and allowed fast cation exchange reaction to release an ultra-large number of Zn(2+) from each cluster that turned on the Zn-responsive dyes...
