The two weaker binding sites were characterized as unspecific binding to the aptamer, while the high‐affinity binding event was shown to be highly specific even at high ionic concentration.
Fluorescence Spectroscopy: An Emerging Excellent Diagnostic Tool in Medical Sciences
There is still a great need for clinical trials and studies on a large scale to establish the validity of this new diagnostic technique, and there is a need to highlight this issue among the scientific community.
