Nanotechnology in Medicine
Nanotechnology in Medicine involves the use of extremely small particles and devices (nanoparticles) to diagnose, treat, and prevent diseases at the molecular level.
• It enables targeted drug delivery, improved imaging, and innovative treatments for conditions such as cancer, cardiovascular diseases, and infections.
• Nanoparticles deliver drugs directly to diseased cells, increasing treatment effectiveness while minimizing damage to healthy tissues and reducing side effects.
• Nano-biosensors and lab-on-chip devices enable rapid and highly sensitive detection of disease biomarkers, supporting early diagnosis.
• Nanoparticles enhance imaging techniques such as MRI and CT scans by providing better contrast and higher diagnostic accuracy.
• Gold nanoparticles and photothermal therapies are being used in targeted cancer treatment and are undergoing clinical development.
• Issues include nanotoxicity risks, regulatory uncertainty, manufacturing complexity, and high costs limiting widespread adoption.
