What is Nanotechnology?
nanoscale to create products with unique properties. It involves working with dimensions and tolerances of less than 100 nanometers, which allows for precise control over the molecular structure of materials.
Nanosensors: These are devices that can detect and measure biological markers at the nanoscale. They are highly sensitive and can provide real-time data.
Nanoparticles: These tiny particles can be engineered to bind specifically to cardiovascular biomarkers, enhancing the detection capabilities of diagnostic tests.
Lab-on-a-chip: This technology integrates multiple laboratory functions on a single chip, allowing for quick and efficient analysis of blood samples for CVD markers.
What Are Nanosensors and How Do They Work?
Nanosensors are devices that can detect changes at the molecular level. They work by interacting with
biomarkers specific to cardiovascular diseases, such as troponin, cholesterol, and C-reactive protein. When these biomarkers bind to the nanosensor, it generates a signal that can be measured and analyzed.
What Role Do Nanoparticles Play?
Nanoparticles can be functionalized with molecules that bind specifically to CVD biomarkers. This enhances the sensitivity and specificity of diagnostic tests. For example,
gold nanoparticles can be used to detect low levels of biomarkers in the bloodstream, providing early warning signs of cardiovascular issues.
How Does Lab-on-a-Chip Technology Work?
The
lab-on-a-chip technology miniaturizes and integrates multiple laboratory processes onto a single chip. This allows for rapid analysis of blood samples, reducing the time required for diagnosis. The chip can process small volumes of blood and detect multiple biomarkers simultaneously, providing comprehensive data for monitoring cardiovascular health.
