Abstract
Background: In recent years, electronic noses have emerged as a component of nanotechnology- based technologies to meet various demands in the health sciences.
Objective: To have a detailed idea regarding the various uses of electronic noses in the early detection of diseases, food spoilage, etc., we need to explore multiple studies.
Methods: Electronic noses are the foundation for the development of biosensors, which are primarily used to identify the many volatile organic chemicals that cause various diseases that are released from the lungs. The electronic nose can distinguish between the breath patterns of healthy people and people with diseases such as cancer, cardiovascular disease, diabetes, neurological problems, etc.
Results: In the field of food industry, bacterial contamination and other kinds of food spoilage can be detected at an early stage by identifying the pattern of gases evolved from these food items using the electronic nose.
Conclusion: Thus, there are versatile applications of electronic noses in the early diagnosis of lifethreatening diseases, chemical industry, food industries, etc., which will be discussed in this review.
Keywords: Electronic nose, bionanotechnology, VOC levels, lung cancer, food spoilage, volatile
