People have made DNA complements with differently rigid supports to the amino acids
-----DNA---------- DNA with strong support
I think placing differently rigid supported probe sequences on a genechip give the ability to rinse or react away the
tested dna sample so a fresh sample may be applied to the gene chip creating a multiple resuse genechip
further a molecule could have pH or electroresponsive pleats which pull to divide n refresh or even use electrical effects to change the available probes action sequence LCD displays rotate n compress liquid crystal with electric charge

||gene chips work on a slightly different process than described. good idea though. it would probably be easier to just use protenous dna as a cleaner.
||Wouldn't obstruct replication, but it does give rise to an error in replication so that the newly formed DNA strand carries the mutation and you've got a virus again. But, uh, this-- all of this is academic. You were made as well as we could make you.
||[norm] I think you missed the idea.
||[beany] I think people have tried using PNA (peptide nucleic
acids) and maybe other DNA analogues for arrays (if that's
what you mean by gene chips). The main problem is cost;
the other problem is specificity, but the main one is cost,
and apparently the chip isn't resuseable enough to make it
