Pharma: May 2007 Archives


May 7, 2007

Coming from a background in spectroscopy, it's always bugged me that diabetics have to take physical samples to measure their blood glucose levels. If we can remotely measure the composition of the sun, 8 light minutes away, we should be able to measure the composition of some blood vessel 1 millimeter away. But no... You need to first take a sample (ouch!) and then do some chemical testing (that's what the test strips are for) [wikipedia background]. The meter is just a mechanical way of reading the result of the blood/strip reaction. We're talking pretty old-school analytical chemistry here. It looks like the situation is improving, though: some scientists in Hong Kong have developed a remote technique based on transdermal infrared spectroscopy.
