Resumen o descripción
Diabetes is a growing problem; in under 18 years, 9% of the world population will have diabetes. Currently, despite technological advances across the healthcare sector, diabetes patients still need to take regular blood samples to monitor their glucose levels. This practice is painful; bothersome; and may induce infections. These factors cause that many patients stop monitoring their glucose, leading to the same levels in the blood reach critical values. An alternative method, is based on the measuring of fingerprints of substances in the breath1. This development is focused on detecting ketone bodies in human breath, those substances are produced by a condition called diabetic ketoacidosis. This condition is characteristic of Type I diabetes, where, in patients in critical situations of acute impairment of insulin in the blood, even present up to 5 ppm of ketone bodies in breath. To measure a so small concentration, as previously mentioned, Raman gas spectroscopy is an excellent tool, specially employing the Surface Enhanced Raman Spectroscopy (SERS)2,3.
In this paper, we show preliminary results on enhancing the Raman diffraction produced by ketone, employing silver nano particles deposited on a polystyrene surface.
