Nanomedicine and Drug delivery

There are a many ways that nanotechnology can make the delivery of drugs more systematic and accost effective treatment for the patient. Numerous biological materials like albumin, gelatine and phospholipids for liposomes, and more substances of a chemical nature like various polymers and solid metal containing nanoparticles are under investigation for preparation of nanoparticles. The hazards that are introduced by using nanoparticles for drug delivery are more than that posed by conventional hazards imposed by chemical delivery.
