Well, it might sound confusing.

Basically, I have several different types of DNA with distinct Watson-Crick sequences

Let's say aggregation between the same DNA molecules depends on the sequence of each DNA, meaning some DNAs tent to aggregate more than the other DNAs.

Let's say you have a mixture of two, three or four different kind of DNAs in a solution that is under a certain condition that drives precipitation/aggregation. How would you be able to study which one aggregates more??

I have been wondering over this issue for a long time, still have not found a viable solution yet.

Any crazy idea is welcome!
