DARPA Requests Replacement To Antibiotics
eldavojohn writes "In the grand scheme of things, antibiotics are a very temporary solution to aid humans in combating bacteria. Bacterial resistance to said antibiotics is an increasing fear and DARPA's 'Rapidly Adaptable Nanotherapeutics' solicitation reveals they're interested in a more permanent solution as modifying the genes of harmless bacteria can result in powerful bioweapons. Like siRNA, DARPA is hoping for more nanomolecules that can specifically target cells and deliver medicine to them anywhere in the body. Most amazing about this proposal is that it's aimed at small businesses and hopes to turn a process that takes decades to study a new antibiotic into a few weeks to manufacture nanomedicine to specifically target bacteria."
Two reasons, both based on the assumption that delivering medicine to them is trickier than destroying them.
First, if you can achieve the goal of deliving medicine to target cells, then destroying them should be trivial, so you've discovered a way to do both.
Second, it sets your sights higher. If your goal is to find a way to deliver medicine to target cells but you miss the mark and the best you can do is destroy them, you've still accomplished something great (as in a cure for cancer). However, if your goal is to figure out a way to destroy target cells and you fail, you accomplished far less.
