Biodegradable Nanostructures – A Novel Means of Combating Antibiotic Resistance

May 10th, 2011

Antibiotic resistance: Two words that strike fear in physicians, hospital workers, and patients and which increasingly grab the attention of media outlets throughout the world.
 
Nanotechnology, the branch of engineering that deals with things smaller than 100 nanometers (especially with the manipulation of individual molecules), continues to make inroads in various areas of medicine and life sciences. Over the past several years we have seen advances in nanomaterials that provide the basis for diagnostic tests, improved vehicles for drug delivery, and novel therapeutics. Among those advances, applications related to the development of novel drugs are especially interesting, particularly where hope in the fight against highly drug-resistant bacteria may be offered.  The ability to carefully engineer nanomaterials to specifically interact with biomolecules suggests that further developments in the therapeutic use of nanomaterials are likely to emerge. Engineered nanomaterials that have ideal drug properties – namely, high selectivity (an ability to hit very specific molecular targets), well understood mechanisms of action that provide high efficacy, and limited side effects – are now on the horizon. So the potential for nanomaterials to replace existing biologics, including monoclonal antibodies and recombinant proteins, is a possibility.
