Deep Submicron EGFET Based on Transistor Association Technique for Chemical Sensing.

Extended-gate field-effect transistor (EGFET) is an electronic interface originally developed as a substitute for an ion-sensitive field-effect transistor (ISFET). Although the literature shows that commercial off-the-shelf components are widely used for biosensor fabrication, studies on electronic interfaces are still scarce (e.g.

EGFET-Based Sensors for Bioanalytical Applications: A Review.

Since the 1970s, a great deal of attention has been paid to the development of semiconductor-based biosensors because of the numerous advantages they offer, including high sensitivity, faster response time, miniaturization, and low-cost manufacturing for quick biospecific analysis with reusable features. Commercial biosensors have become highly desirable in the fields of medicine, food, and environmental monitoring as well as military applications, whereas increasing concerns about food safety and health issues have resulted in the introduction of novel legislative standards for these sensors. Numerous devices have been developed for monitoring biological processes such as nucleic acid hybridization, protein⁻protein interaction, antigen⁻antibody bonds, and substrate⁻enzyme reactions, just to name a few.

Carbon Nanospikes on Silicon Wafer for Amperometric Biosensing Applications.

Carbon electrodes have gained wide popularity in biosensing applications in recent years. In this paper, we discuss carbon nanospikes fabricated using plasma enhanced chemical vapor deposition on a silicon wafer. Carbon nanospikes are preferred over other carbon nanostructures due to their batch reproducibility.

Medical Devices for Pediatric Apnea Monitoring and Therapy: Past and New Trends.

Apnea in the pediatric population is associated with increased morbidity and mortality in a large number of developed as well as developing countries. It is even more prominent in preterm newborn infants and is commonly referred to as apnea of prematurity. Its current diagnosis and therapy involve the use of traditional technologies, which often result in discomfort to the infants due to the use of invasive devices attached to their sensitive skin, especially in overnight clinical sleep analysis (for over a 12- or 24-h period).
