Building a Better HIV Drug: Nano-Formulated Medicines

Types of Nanomedicine

Types of Nanomedicine

There are two types of nanomedicines, Owen said: nanoscale-containing drugs and solid drug nanoparticles (SDNs).

Nanoscale-containing drugs are often called "drug-delivery vehicles" because they are carriers that can either be loaded with antiretrovirals or surface-functional groups with antiretrovirals. They can be diverse, ranging from inorganic, insoluble nanoparticle carriers (such as gold nanoparticles) to lipid-based nanoparticles (such as liposomes) to organic polymeric nanoparticles (such as dendrimers).

SDNs, often called "nanosuspensions," are very small particles of the solid drugs themselves. Each of these particles is about one millionth the size of a human hair. They can be made either by milling, in which a solid chunk of a drug is ground down until it's nano-sized, or via the precipitation of solutions to form nano-sized versions of the drug.
