We propose to develop a sensitive, differential microcalorimetric biosensor device using thin polymer films displaying a pyroelectric response. polyvinylidene fluoride (pvdf) films are capable of detecting the heat of a human body up to fifty feet away and have recently been employed in various ir… More

The biosensor field is multidisciplinary, encompassing many types of measuring techniques and devices. thermometric andmicrocalorimetric techniques for enzymatic and immunoenzymatic analysis have yielded good results; however,to date, the methods and equipment remain relatively complex, expensive,… More

The testing for salmonella currently involves methodology that requires 3-8 days to complete and a fairly sophisticat ed skill level to perform. this project is designed to d develop both manual and biosensor-based homogeneous assays that will reduce the detection time of salmonella to within 24… More

Biosensors are a rapidly emerging biotechnology engineering effort that is multidisciplinary, encompassing many types ofmeasuring techniques and devices. we propose to explore thefeasibility of developing a sensitive, miniature differential thermometric biosensor device using thin polymer films… More
