Prior to implementation of volatile organic compound (VOC) analysis in clinical practice, substantial challenges, including methodological, biological and analytical difficulties are faced. The aim of this study was to evaluate the influence of several sampling conditions and environmental factors on fecal VOC profiles, analyzed by an electronic nose (eNose). Effects of fecal sample mass, water...

Prostate cancer (PCa) represents the cause of second highest number cancer-related deaths worldwide, and its clinical presentation can range from slow-growing to rapidly spreading metastatic disease. As characteristics most cases PCa remains incompletely understood, it is crucial identify new biomarkers that aid in early detection. Despite prostate-specific antigen serum (PSA) levels, prostate ...

Aroma teh merupakan sesuatu yang sulit diukur karena membutuhkan kejelian dalam indra penciuman sehingga untuk mengukur aroma rangka mempertahankan kualitas yaitu menggunakan alat Hidung elektronik/enose terdiri dari sensor-sensor digunakan mendeteksi atau bau. elektronik/Enose terbuat beberapa larik sensor gas dan memiliki sistem kerja seperti manusia. Melalui e-nose hijau dapat diidentifikasi...

In a fire investigation the rapid detection of the presence of ignitable liquids like gasoline is of great importance as it allows appropriate treatment of the remains, the identification of prevention methods and detects the possible presence of an arsonist. In some cases, analysts cannot access the fire scene in the first few hours due to the dangers involved in the situation and, as a conseq...

Mango fruit (Mangifera indica L.), cv. ‘Cogshall’, ‘Kent’ and ‘Keitt’ were harvested at different maturities (61–115 d past flowering and 0–307 average g fresh weight for ‘Cogshall’) and at different sizes (364–1563 and 276–894 average g fresh weight for ‘Keitt’ and ‘Kent’, respecively). Immediately after harvest (green) or after 1 week of ripening at room temperature (ripe), fruit were homogen...

In this paper, we describe a new low-cost and portable electronic nose instrument, the Multisensory Odor Olfactory System MOOSY4. This prototype is based on only four metal oxide semiconductor (MOS) gas sensors suitable for IoT technology. The system architecture consists of four stages: data acquisition, data storage, data processing, and user interfacing. The designed eNose was tested with ex...

BACKGROUND The acute respiratory distress syndrome (ARDS) is a common, devastating complication of critical illness that is characterized by pulmonary injury and inflammation. The clinical diagnosis may be improved by means of objective biological markers. Electronic nose (eNose) technology can rapidly and non-invasively provide breath prints, which are profiles of volatile metabolites in the e...
