Abstract:
Immunoassays on nanopatterned chips through TIRS detection based on reconstructing the three dimensional position provided a nanoscale accuracy of the lateral resolution by using the z-stage controller in the spatial range up to 10 nm. This method offers highly accurate and sensitive quantification with the zeptomolar (∼10(-21) M) detection of proteins.
