New trends in infrared spectroscopy assisted biodiagnostics
Development of new hardware accessories in field of IR spectroscopy, new sampling techniques and also
brilliant movements in chemometrics have all led to huge diagnostic approaches based up on IR spectroscopy.
Some of these have even been transformed to technology and are utilized in pathobiologic and diagnostic
laboratories. Together with technical improvements the clinical chemistry specialists are also attending to the
methods by which the results are obtained:
Statically more powerful
●
Rapid
●
Capable of generalization
●
Not to be invasive
●
The last item is really important for medical science researchers because they prefer not to impose any
damage on the inspected organ or any other part of body.
