I just watched this TED talk by Fiorenzo Omenetto about the amazing qualities of silk:
Especially the section where he talked about timed degradation of the material made me think. If this works out as presented (and basic research always has to be taken with a pinch of salt), it has great implications for medicine.
In fields like psychiatry, constant delivery of medication is an important part of treatment. But especially schizophrenic or bipolar (manic-depressive) patients often have problems adhering to their medication scheme. When they are in a stable phase, they see the need for the medication and are willing to take it. But once they start forgetting the medication a few times (and adhering to a scheme with several tablets a day is difficult, even if you are not psychotic), the condition deteriorates. This makes the patient even less compliant and soon they are in a downward spiral, usually ending up on the psychiatric emergency ward.
So a method to implant a biodegradable film, loaded with the required dose for several days or weeks might help the patients stick to their medication and might stabilize them over the long term. Which in turn helps the patients to cope with their disease and saves great costs to society.
