Profile: Gold Colloid, Co. specializes in providing lateral flow assay solutions. Gold nanoparticles are a revolutionary technology that is changing the way we diagnose disease. These tiny particles have unique properties that make them ideal for detecting even the smallest amounts of biological molecules. Gold nanoparticles can be used to create sensors that can detect the presence of specific proteins, DNA, or RNA. This can be used to diagnose diseases at an early stage, when they are most treatable. Gold nanoparticles can also be used to track the movement of molecules in the body, which can be used to study the progression of disease or to monitor the effects of treatment.
