Result of SAM
- We observe that there were few signs anything after washing in ①,②,④ and ⑤．On the other hand, ③ and ⑥ were left water. This is expected that this spot of gold surface is covered with DNA by thiol conjugation, and became partially hydrophilic. Other spots are still hydrophobic in that there are no conjugations of DNA.
- From this result, we were determined that thiol conjugation is completed.
