NTT DoCoMo Demonstrates Molecular Delivery System for Molecular Communication

Here's the press release, which was reported by Engadget.

I made this comment on their post:

When I hear "molecular communication" I immediately think of hormones or neurotransmitters.

The press release talks of "analyzing biomolecules in a drop of sweat or blood using a mobile phone equipped with a biochip." I guess you could call glucose a biomolecule.

In this case, "artificially synthesized DNAs and chemically energized motor proteins" could create insulin and release it as needed, replacing the malfunctioning pancreatic beta cells of the patient with diabetes.

As far as monitoring "excitement, emotion, stress...," I don't know if you want to be attached to a device that will deliver a hormone that will turn you into a Stepford Wife (or Husband) just because someone took your parking space.

It's scary to think that all this can happen automatically, and flawlessly. Their press release mentions that "the biochemical analysis would be transmitted to a medical specialist." So there might be a human somewhere monitoring all these users, pinging these devices to release serotonin when it looks like they might be getting a little antsy.
