Scientists have recently developed a new biosensor that can detect an elusive metal essential to life: molybdenum. This revolutionary technology has the potential to revolutionize the study of biology, as it is capable of detecting molybdenum in a much more sensitive and specific way than existing methods. The biosensor is based on the use of an engineered enzyme that binds to molybdenum and produces a fluorescent signal that can be detected in real-time. This unique capability could provide researchers with a valuable tool to study the role of molybdenum in biological processes, such as its role in the nitrogen cycle, cellular metabolism, and enzyme activity. The implications of this discovery could enable scientists to better understand the importance of this metal in the functioning of all living organisms.
