Biosensors are analytical devices that convert a biological response into an electrical signal. Nanotechnology enhances biosensors in the following ways:
- Sensitivity: Nanomaterials like gold nanoparticles and carbon nanotubes increase the surface area, allowing for the detection of low-abundance biomarkers. - Selectivity: Functionalized nanomaterials can be designed to bind specifically to target molecules, reducing false positives. - Speed: The small size of nanomaterials enables faster reactions and quicker detection times.
