What are Biological Sensors?

Biological sensors, or biosensors, are analytical devices that convert a biological response into an electrical signal. These devices typically involve a biological recognition element, such as enzymes, antibodies, or nucleic acids, coupled with a transducer to detect chemical or biological substances. The result is a quantifiable signal that can be easily measured and analyzed.

Uses of Biological Sensors

  1. Disease Detection:
    • Cancer Biomarkers: Detecting proteins or DNA mutations associated with cancer.
    • Infectious Diseases: Identifying pathogens like bacteria or viruses quickly and accurately.
  2. Environmental Monitoring:
    • Pollutant Detection: Monitoring water and air quality by detecting contaminants.
  3. Glucose Monitoring:
    • Diabetes Management: Continuous glucose monitoring systems for diabetic patients.
  4. Pregnancy Tests:
    • Hormone Detection: Identifying the presence of human chorionic gonadotropin (hCG) in urine or blood.
