Controlled by Google? Over my cold, dead corpse...
Google and drug giant GlaxoSmithKline are spending £540m on a new joint venture, Galvani Bioelectronics, in a bid to develop and commercialise bioelectronic medicine. The partnership between Verily Life Sciences, previously known as Google Life Sciences, and GSK, will boost the British pharmaceutical giant’s efforts in …
"Current glucose testing methods can be quite painful as it involves pricking the finger to draw blood several times a day."
No real pain - literally a pinprick at most. You do it to yourself - which always reduces the pain the brain registers compared to someone else doing it to you. Apparently the finger tip can become slightly insensitive to touch if you have to do it several times a day.
A real benefit for all diabetes sufferers would be if it is measuring glucose levels continuously. Currently that is done by a wire probe inserted under the surface layer of the skin on the abdomen, Results are sent by wireless to a monitor carried on the body. A probe is only effective for a few days - and care has to be taken not to dislodge it prematurely.
The probe's glucose readings are delayed by several minutes before a change permeates to the test area's fluids. It would be interesting to know if tears are faster or slower indicators of the current glucose level.
The benefit of continuous glucose measurement is that you can see exactly how your body is reacting to different foods. With strip tests you would have to use several over a two hour period to measure the initial spike and determine the effective Glycaemic Index (GI) of your meal or snack.
If someone needs insulin to control their glucose level then a continuous monitor could control an insulin pump to give exactly the right dose rate to counter the changing levels. That would make a very big difference to people who live their whole lives with Type 1 Diabetes - with the higher risk of hyperglycemia and the potentially fatal hypoglycemia.
"Galvani Bioelectronics" - the name alone made me twitch already.
So yes, there is a lot of potential in this (see above post regarding diabetes as one example).
But I can't help thinking that G00gle dreams of nanobots in my nervous system that will make me actually click on the ads they show me.
