Biotechnology and optical fiber sensors have numerous applications. Optical fiber sensors are used in biotechnology for real-time monitoring of biological processes, such as measuring pH levels, temperature, oxygen concentration, and biomolecular interactions. These sensors provide accurate and precise data, enabling better control and optimization of bioprocesses in fields like pharmaceuticals, biofuels, and agriculture. Additionally, optical fiber sensors are employed in medical diagnostics, detecting biomarkers, pathogens, and physiological parameters. Their non-invasive nature, high sensitivity, and compatibility with biological systems make them invaluable tools in biotechnology for research, quality control, and healthcare applications.
