In this investigation, we present a novel label-free immunosensor platform based on inorganic barium strontium titanate (BST) thin film and interdigitated microelectrodes for clinical point-of-care application. The immunosensor is based on non-faradaic process, using DI water as electrolyte. As proof of concept, anti-human IgG, a common biomarker found and associated with many diseases was immobilized...
In this position paper we propose a new approach to provide online in-vivo recordings of organ activity in real time and to overcome three major shortcuts of currently used invasive glucose sensors. In the context of diabetes, standard glucosensors recognize only glucose, whereas circulating lipids as well as amino acids are known to increase the demand in insulin and, under physiological circumstances,...
Salmonalla is one of the major causes of worldwide foodborne diseases. Conventional microbiological detection methods are time consuming and the recent signal transduction schemes based on fluorescence spectroscopy, surface plasmon resonance and others require specialized bulky and expensive instruments, which will increase the overall production cost in the food industry. This paper reports for the...
The concept of a novel biosensing system for the detection of bacteria and bacterial growth that could potentially offer shorter detection periods, specificities, and higher sensitivities compared with conventional methods is briefly described. The proposed biosensing microsystem uses magnetotactic bacteria that can be controlled by software and a microelectronic circuit embedded in the detection...
Bioassays involve multi-stage sample processing and fluidic handling, which are generally labor-intensive and time-consuming. Using microfluidic technology to integrate and automate all these steps in a single chip device is highly desirable in many practical applications such as clinical diagnostic and in-field environmental testing. We have developed self-contained and fully integrated biochip systems...
