Microbial biofilms are associated with drastically enhanced resistance to most of the antimicrobial agents and with frequent treatment failures, generating the search for novel strategies which can eradicate infections by preventing the persistent colonization of the hospital environment, medical devices or human tissues. Some of the current approaches for fighting biofilms are represented by the development of novel bi Read More

The increasing morbidity and mortality of infectious diseases is an increasing concern. Despite the continuous development and synthesis of new antimicrobial drugs, microbial pathogens are exhibiting increased multi-drug resistance. Nanomaterials display unique and well-defined physical and chemical properties including a very high surface area to volume ratio, and new approaches for antimicrobial therapies have attem Read More

Bacterial and cancer cells that are resistant to current specific therapy have become an increasingly important public health problem over the past several decades. Consequently, the search for new anti-infection and anti-cancer treatments of drug resistant microbes has attracted a lot of attention. Recently, nanostructures have been shown to be efficient antimicrobial agents that do not induce drug-resistance. The presen Read More

Smart multifunctional polymeric nanocarriers able to respond to physicochemical changes in their environment or to external stimuli represent a new paradigm in the field of pharmaceutical formulations for controlled drug delivery. The introductory part of the present review deals with this new concept and presents the main advantages resulting from the use of such nanovehicles instead of conventional, much larger drug Read More

Due to the great prevalence of persistent and recurrent implanted device associated-infections novel and alternative therapeutic approaches are intensely investigated. For reducing complications and antibiotic resistance development, one major strategy is using natural or synthetic modulators for targeting microbial molecular pathways which are not related with cell multiplication and death, as Quorum Sensing, viru Read More

The emergence of antibiotic resistance in microbial strains is representing one of the major threats to public health worldwide, due to the decreased or total cancelling of the available antibiotics effectiveness, correlated with the slow development of novel antibiotics. Due to their excellent biodegradability and biocompatibility, the synthetic polymers could find a lot of biomedical applications, such as the developm Read More

The present review is intended to bring together the main advances in the field of nanostructured biomaterials with antimicrobial properties. It is generally accepted that the discovery of antibiotics was of great importance but, nowadays new antimicrobial agents are needed and/or their better administration routes. The limitation of the use of antibiotics is essential because of the following reasons: the excessive use of an Read More
