Label-free optical biosensors present good performance in detecting biological systems with high sensitivity and multiparameter analysis, thereby promoting significant advances in clinical diagnostics, drug discovery, food process control, and environmental monitoring. 0000381364 00000 n 0000129563 00000 n Sensors for pH are based on the protonation/deprotonation of pH indicator dyes [1] and sensors for cations and anions use a combination of pH indicator dyes with selective ionophores (via the mechanisms of coextraction or ion-exchange) [2]. 0000030226 00000 n 0000280793 00000 n 0000197567 00000 n (l) it is believed that interdisciplinary teaching and interdisciplinary conferences like Europtrode have contributed to an improved understanding and interaction between scientists involved in optical sensor technology. 0000279432 00000 n The analyzers were also assessed in DO measurements of a number of natural waters. 0000021934 00000 n Surface modification by selecting appropriate modification routes including plasma tailored for specific biomedical applications is limited not on polymers, but may be applied to stainless steel for update of its biomedical applications. In most cases, however, the very same attractive features have led (so far) to expensive instrumentation and/or complex methods compared to, for instance, the well-established electrochemical sensors. A more sophisticated and synthetically challenging approach is to use selective fluoro- and chromoionophores [1,3,4]. Optical Sensor converts light rays into electrical signal. When the tip is air, infra-red light reflects internally round the tip to the . View in Order History. There are several physical methods to obtain this transducing signal such as those based on amperometric, potentiometric or acoustic systems. The areas of application for such devices are numerous, ranging from pharmaceutical, agricultural, environmental, forensic, and food sciences to wearables and clinical diagnostics, especially in resource-limited settings. Because proteins mediate nearly all cellular activities, biochips have also been applied at the protein level (“proteomics”) [8, 9]. While the victories over bubonic plague (Yersinia pestis), whooping cough (Bordetella pertussis), polio and smallpox (variola) are clearly significant, new diseases represented by human immunodeficiency virus (HIV), as well as the tragic reality of biological agents used as weapons of terrorism and mass destruction [6] — offer sobering evidence that the battle against infectious disease is far from over [7]. In addition, optical sensors do not require electrical signals in the sensing area and therefore can be operated in hazardous environments of industrial plants. The savings are even more important in the case of a Mars rover since power and radiation-hardening requirements lead to severely constrained computational resources.
