Provided are compositions and methods for modulating quorum sensing in microbes. The compounds are AI-2 analogs and as such have structures similar to 4,5-dihydroxy-2,3-pentanedione that can act as agonists/antagonists of quorum sensing. The compounds are useful for modulating quorum sensing in bacteria and can be used in methods for prophylaxis or therapy of bacterial infections and for reduction of biofilms.
摘要:
The present invention provides arrays comprising polypeptides associated with viruses that are immobilized to an electrode in a directional orientation such that the surface area of the electrode and the sensitivity of the electrode is increased. The invention also provides for methods of diagnosing and/or prognosing a certain disease or disorder through contacting a sample from a patient with an array comprising the polypeptides associated with viruses.

摘要:
Surfaces having a hierarchical structure—having features of both microscale and nanoscale dimensions—can exhibit superhydrophobic properties and advantageous condensation and heat transfer properties. The hierarchical surfaces can be fabricated using biological nanostructures, such as viruses as a self-assembled nanoscale template.
