Gold Nanoparticle Conjugate Optimization: pH, Antibody Loading, and Blocking
Introduction A gold nanoparticle conjugate rarely fails in the lab. It fails three weeks later, on the production floor, when a formulation that worked perfectly at bench scale suddenly produces faint test lines or inconsistent batches. Process engineers scaling colloidal gold rapid tests know this pattern well: the chemistry looks stable in a 10 mL flask, […]
