Antimicrobial systems

The body possesses a number of non-specific antimicrobial systems which are operative at all times against potentially pathogenic microorganisms. Prior contact with the infectious agent has no intrinsic effect on these systems. 

Research is under way to investigate the potential to develop the natural antimicrobial system present in milk, such as the lysozyme, lactoferrin,...

The use of antimicrobial systems in plastics products is discussed, with particular reference to the products from Wells Plastics. It is emphasised that it is important to choose the correct system to suit the product and its intended application, and that the efficacy of the antimicrobial system must be verified through appropriate antimicrobial... 

Modified polysaccharide biopolymers have found applications from permselective membranes to ionically conductive membranes for fuel cells. In this review, ionically selective membranes in particular will be explored. Recent studies and advances in using modified polysaccharides for food applications will also be reviewed with specific attention given to their potential uses in the development of active food packaging solutions, which include antimicrobial systems, coatings and bioactive compound delivery systems. 

The ongoing efforts have been promising, especially in the antimicrobial food packaging area. For this part, we would like to summarize the recent developments on antimicrobial systems utilizing chitosan, cellulose, their derivatives and blends (Table 3.3).

One reason can be found in their main characteristics, such as a well-defined size and structure, flexibility, monodispersity and multivalent molecular surface. In particular, cationic dendritic systems have been studied as non-viral delivery carriers of nucleic acids such as oligonucleotides, siRNA, mRNA or DNA and as antimicrobial systems. 

Prior to the flood, hospital and university researchers had designed a study protocol to investigate the effect of surface modification wifli silane antimicrdnals on infection rates within the Bone Marrow Transplant, Hematology and Oncology areas in the hospital. The flood and subsequent microbial contamination preempted the study. But, investigation of various antimicrobial systems to achieve sustained microbial control during the study provided an important tool for use in remediation and beyond.
