Naphthalene-Dipeptide Hydrogels Destroy Antibiotic-Resistant Bacterial Biofilms

Novel hydrogels derived from self-assembling dipeptides conjugated to naphthalene were shown to dissolve bacterial biofilms, which indicated considerable promise for use in constructing bacteria-resistant nanomaterial structures, biomaterials, and drug delivery devices.  More...

They are found in the outer membrane of Gram-negative bacteria, and elicit strong immune responses in animals (Photo courtesy of Wikimedia Commons).

Elevated Levels of IgG2 Antibodies Protect Some Types of Gram-Negative Bacteria

The finding that an overabundance of a certain class of antibodies protects some bacteria from the effects of antibiotics has marked implications for our understanding of the protection generated by natural infections and for the design of vaccines, which should avoid inducing such inhibitory antibodies.  More...
