ssDNA, our best aptamer for Ag+ ion 2
Silver is one of the most wasted precious metals that can be found in effluents, streams and even food. As our project is to develop a precious metal recycling platform, we chose Ag+ as the demonstration ion of this phase of the project. Aptamers are oligonucleotides that can bind targeted molecules with its secondary structures, in our project, Ag+ ion. BBa_K3798005 is a Ag+ aptamer obtained from a previous paper[1], and this particular aptamer had shown outstanding abilities efficiency and satbility in Ag+ ion capture.

Characterization
Binding efficiency and stability
As can see above aptamer 3 and 4 has the best binding efficiency with Aptamer 3 having a higher binding ability (the remaining ion concentration of Aptamer 3 is 86ug/L lower than that of Aptamer 4) and Aptamer 4 having better stability when binding (lower error bound). Because having 90% of binding efficiency is enough for our use and having higher binding stability means that the treated effluents would have a more consistent results that is essential for industrial use, Aptamer 4 was chosen to be subject of further experiments.
