Highly Sensitive and Selective Colorimetric Sensors for Uranyl (UO(2)(2+)): Development and Comparison of Labeled and Label-Free DNAzyme-Gold Nanoparticle Systems
Colorimetric uranium sensors based on uranyl (UO(2)(2+)) specific DNAzyme and gold nanoparticles (AuNP) have been developed and demonstrated using both labeled and label-free methods. In the labeled method, a uranyl-specific DNAzyme was attached to AuNP, forming purple aggregates. The presence of ur...
