Excerpts: Naturally alluring as potential
alternatives to conventional antibiotics, peptides - molecules to
combat bacterial infections - are produced by a wealth of plants
and animals. But unlike antibiotics, peptides are large and don't
get transported to the site of infection, making them all but
