Researchers at Northeastern University are using nanosensors implanted into the skin — similar to a tattoo — and a modified iPhone to measure sodium and glucose levels in patients. The implications for this could be tremendous, but first, here’s how it works:
“The team begins by injecting a solution containing carefully chosen nanoparticles into the skin. This leaves no visible mark, but the nanoparticles will fluoresce when exposed to a target molecule, such as sodium or glucose. A modified iPhone then tracks changes in the level of fluorescence, which indicates the amount of sodium or glucose present.”

Last week I had some blood tests taken before a doctor’s appointment. I went to a commercial lab facility, one of several dozen centers for collecting specimens have opened up in otherwise-unrented Manhattan office spaces lately.
I have to say I really like getting my blood work done at this place, if and when I need blood tests. And it’s gotten better over the past few years.
First, pretty much all they do in the lab center is draw blood and collect other samples based on a doctor’s orders. So the people who work there are practiced at phlebotomy, because it’s what they do most of the time. The guy who drew my blood last week did the same a year or two ago, and he was good at it back then. He used a butterfly needle and I didn’t feel a thing.
Second, they seem organized and careful about matching specimens to patients. The man who drew my blood didn’t just confirm my name and date of birth, but he had me sign a form, upon my inspecting the labels that he immediately applied to the tubes of blood he drew from my right arm, that those were indeed my samples and that I was the patient named Elaine Schattner with that date of birth and other particulars.

Here is a project from the folks at the Department of Mechanical Engineering at Imperial College London, and its Mechatronics in Medicine Laboratory, who are bent on developing an “active robot designed to take blood samples from the ante-cubital fossa…”
The Bloodbot identifies the location of a suitable vein by pressing a probe against the surface tissue of the ante-cubital fossa and measuring the force on the probe. The difference in the characteristics of the tissue from its surroundings, in response to the applied force, indicates the presence of a vein.
Once a suitable vein has been found, it inserts a needle under force control. When the needle penetrates the vein (identified by its force/position profile), the control system prevents further insertion, thus avoiding overshooting the vein.
We think they need to combine this robot with VeinViewer for a more accurate, and probably spookier, experience.
The Bloodbot Project…
