| Title: Semiconductor Nanostructured based Gas Sensor Towards Human Health Monitoring: Synthesis to prototype development | |
| Abstract: Nowadays sensors are omnipresent and became an indispensible part of our society. Besides conventional use, gas sensor based breath analyzer has attracted increasing interest among the scientist, technocrats and clinical communities. This is a non-invasive technique which can provide information of diseases and monitoring of therapy just analyzing exhale breath. There exists a huge market for gas sensors which is ever increasing due to new application possibilities including non-invasive breath analysis for monitoring diseases.
Human breath is composed of several gasses and hundreds of volatile organic compounds (VOCs). An accurate detection of specific gas /VOCs in exhaled breath, known as biomarkers, can provide essential information for the diagnosis of those diseases. The compounds of interest (VOCs) are generally found at ppb /sub-ppm level in healthy human breath which can increase several times in the breath of patients. However, the ability to prepare novel nanomaterial having high sensitivity, good resolution at sub-ppm /ppb level and insensitive toward moisture is required for development of breath analyzer, is currently not achievable. This presentation will cover all the aspects starting from preparation of novel nanocomposites to fabrication and performance of prototype device in detail.
