BIO BRIEFS
Healing the sick with nano-bio hybrids
In recent years, researchers have learned how to combine biomolecules such as DNA, RNA and lipids
with nanomaterials to develop medical diagnostics and treatments. One hybrid – DNA and carbon
nanotubes (CNTs) – may soon be used to treat cancer tumors and deliver drug therapies to cells.
 
Using metal-organic nanocages to model viral capsid proteins
Viruses lie on the border between living cells and inert matter. Their genetic material, or genome, is
housed inside a protein shell, or capsid. Like living cells, viruses can reproduce but they need to
hijack the biochemical machinery of a host cell to do so.
 
Fighting heart disease one molecule at a time
Understanding how and why white blood cells attach to blood vessel walls may be critical in treating
atherosclerosis, or hardening of the arteries.
