1 Label-free optical biosensors: An introduction
The ability to study interactions among biomolecules, to observe the activity of cells, and to detect analytes specifically from bodily fluids, manufacturing processes, or environmental samples are cornerstones of life science research, pharmaceutical discovery, medical diagnosis, and food/water safety assurance. These capabilities and many others are enabled by the ability to perform biochemic...
متن کاملLabel-free cell-based assays using photonic crystal optical biosensors.
Biosensor technologies that have been primarily used in the past for characterizing biomolecular interactions are now being used to develop new approaches for performing cell-based assays. Biosensors monitor cell attachment to a transducer surface, and thus provide information that is fundamentally different from that provided by microscopy, as the sensor is capable of monitoring temporal evolu...
متن کاملLabel-free electrochemical biosensors for food and drug application
In food sector, there is a huge demand for rapid, reliable, user & eco-friendly biosensors to analyse the quality and safety of food products. Biosensor based methodology depends upon the recognition of a specific antigens or receptors by corresponding antibodies, aptamers or high-affinity ligands. The first scientifically commercialised sensors were the electrochemical sensors used for the ana...

متن کاملLabel-free biosensing by means of optical micro-ring resonator
Micro-ring resonators have been widely employed, in recent years, as wavelength filters, switches and frequency converters in optical communication circuits, but can also be successfully used as transducing elements in optical sensing and biosensing. Their operation is based on the optical coupling between a ring-shaped waveguide and one or more linear waveguides patterned on a planar surface, ...
