Implanted nanotube sensor monitors health for up to one year

http://web.mit.edu/newsoffice/2013/new-implantable-sensor-1103.html

MIT scientists are developing injectable and embeddable carbon nanotube sensors that can monitor blood sugar levels, inflammation, and other health issues.  The continuous monitor can stay in a person’s body for up to a year.

Researcher Nicole Iverson wrapped carbon nanotubes in DNA sensitive to nitric oxide and made two types of sensors.  One is injectable for short-term monitoring of problems such as a reaction during surgery.  The other is implanted for long-term monitoring of cancer, diabetes or immune reactions to artificial joints.

The next step will be to link the nanotube sensor to a medical device, such as an insulin pump. The sensor would be implanted under a person’s skin, detecting blood glucose levels. The nanotubes would fluoresce when exposed to certain levels of glucose, and the light could signal the pump to start working and release insulin.

    Through a sapphire coated mineral crystal cover,
    start to see the watch. This sort of price tag is still acceptable for the regular person as well as those who are style-inclined.
    Not very spy-like, but beneficial in my daily life.

    After all, exactly what is the point of paying thousands on a watch you can not
    use for life. They tell individuals who you have money so you aren’t afraid
    to invest it on something nice for yourself. If the timepiece is automatic,
    turning the hands is able to keep it working.

    to manually code with HTML. I’m starting
    a blog soon but have no coding expertise so I wanted to get
    guidance from someone with experience. Any help would be greatly
    appreciated!
