In this study, it is aimed to determine the glycemia (blood sugar) level of the diabetics by analyzing the acetone odor participated in their breath (exhalation) with the help of QCM (Quartz Crystal Microbalnce) sensor based Electronic Nose. The level of acetone concentration in humans' breath is as low as 0, 1-10 ppm. In order low level acetone concentration to be sensed by the sensors, it is needed...
This paper presents the design and development of a novel osmotic glucose sensor that will be miniaturized to record the concentration of blood sugar in people suffering from diabetes mellitus. Key sensor components based on microfabrication technologies include a 1.03 bar differential silicon pressure transducer, nanoporous membrane and a 2 μW electronic interface combined with a wireless inductive...
Human cardiac troponin I (cTnl) is a specific protein of cardiac muscle. The detection of the content of cTnl in human serum shows high specificity for diagnosing acute myocardial infarction. For preparation of diagnostic reagents of myocardial infarction, cTnl is isolated directly from human cardiac muscle by skeletal TnC-sepharose 4B affinity chromatographic column. The molecular weight and the...
In the recent past, several sensors have been developed which allow continuous glucose monitoring (CGM) for several days. CGM can improve diabetes management and in particular decrease the risk of hypoglycemic events. However, CGM sensors measure glucose concentration in the interstitial fluid (ISF) rather than in plasma and ISF lags plasma glucose. The purpose of this work is to investigate if plasma...
