Nanotechnology Drug Delivery Systems: An Insight

One of the most important applications of nanotechnology in medicine involves use of nanoparticles to deliver drugs, and other therapeutic substances to specific types of cells (such as cancer cells). Nanosized structures and devices are smaller than human cells which are around 10,000 nm in diameter and similar in size to biomolecules such as enzymes, proteins (hemoglobin is 5 nm in diameter). Due to their small size, nanoparticles can also penetrate the blood-brain barrier which is impervious to most therapeutic and imaging agents.
