- Resumen
The scientific and technological progress in recent decades has given rise to sensor systems capable of obtaining, processing, and transmitting information on a multitude of physical and chemical aspects and using it to improve key aspects of many areas of our society. Chemical sensors are compact, miniaturized devices capable of offering alternative solutions to conventional instrumental analysis techniques. In particular, biosensors have become highly relevant due to the progress they have brought to strategic sectors such as clinical diagnostics, the food industry, and the environment.
Optical biosensors rely on interactions between light and matter to transduce biosensing events and provide important features such as stability, immunity to external stimuli, and versatility in the development of label-free approaches. This last aspect usually exploits nanoscopic phenomena and its development in closely linked to the progress in nanoscience and nanotechnology.
A key aspect of label-free biosensing is the discovery and development of new transduction strategies. In this regard, although they are at an early stage of development, diffractive biosensors offer great potential in terms of simplicity, miniaturization, and the ability to minimize unwanted signals from non-specific interactions, among other aspects.
