What can biosensors detect?

Biosensors can detect a diverse array of substances, including biomolecules such as glucose, cholesterol, and proteins, as well as pathogens, toxins, and environmental pollutants. For instance, glucose biosensors are widely used to monitor blood sugar levels, while DNA biosensors can identify specific genetic sequences in diagnostic tests. The specificity and sensitivity of biosensors make them effective tools for detecting even low concentrations of target analytes in complex samples.
