STORY / PUBLIC SOURCE RECORD
Biosensors in healthcare
- Published 13 February 2025; updated 25 March 2026; estimated reading time 2 minutes. The article defines biosensors as analytical devices that turn biological responses into electrical signals. It lists heart rate, blood pressure, oxygen saturation and respiratory rate as measurable indicators and mentions disease monitoring and drug discovery as uses.
- It describes three parts: a bioreceptor (such as an enzyme, antibody or nucleic acid) interacts with the target substance; a transducer converts that interaction into a measurable signal; and a detector processes and displays the result.
- Biosensors can be embedded in smartwatches and fitness trackers for continuous physiological data collection, which the page says can reveal abnormalities early and support proactive or personalised care. It cites an external estimate that the wearable medical-device market was growing at 29% annually and might reach USD 197 billion by 2030; this is a source forecast reproduced by the article.
- The listed advantages are immediate feedback for treatment adjustments, sensitivity to low analyte concentrations, non-invasive continuous monitoring, and possible cost reduction through early detection and fewer extensive lab tests.
- Pharmaceutical applications described include identifying potential trial candidates, measuring drug-target interactions and detecting contaminants in formulations. Biotechnology uses include monitoring cell processes to optimise production of vaccines, enzymes and antibodies. The page also points to nanotechnology and names Norwegian company Zimmer & Peacock’s wearable electrochemical biosensors, which customers can use to develop apps for glucose, lactate, pH and potassium measurements.
