What Are Some Nanotechnology-Based Methods for Disease Detection?
Nanoparticles: These tiny particles can be engineered to bind with specific molecules related to diseases, such as cancer cells or viruses. When introduced into the body, they can highlight the presence of these molecules, making them detectable through imaging techniques. Nanosensors: These sensors can detect minute changes in the biological environment, such as the presence of disease-specific proteins, DNA, or RNA sequences. They offer high sensitivity and specificity, allowing for early diagnosis. Quantum Dots: These are semiconductor nanocrystals that can be used in medical imaging. They emit light when exposed to ultraviolet light, helping in the visualization of cancer cells or other disease markers at very early stages.
