Abstract:
A femtomolar digital homogenous immunoassay is developed based on sensitively distinguishing the immunocomplexes labeled with quantum dot (QD) aggregates from the excessive free monodisperse single QDs. The success in quantifying the carcino-embryonic antigen and alpha-fetoprotein in plasma validated the feasibility of our approach for clinical tests.

Dot Product
In engineering, the dot product of any two vectors is the product of the magnitudes of the vectors and the cosine of the angle between them. It is denoted by a dot symbol between the two vectors.
Consider a vehicle pulling an object along the ground using a rope. If the rope makes an angle with the horizontal axis, the work done can be calculated using the dot product of the force applied and the object's displacement.
