章节摘录

版权页：插图：CHAPTER 1 DecontaminationUsing NanotechnologyManoj K. Ram and Ashok KumarNanotechnology Education Research Center,University of South Florida, Tampa, Florida1.1 Introduction Nanotechnology can be defined as the synthesis, characterization,and application of materials science and engineering and deviceswhose smallest functional organization in at least one dimension ison the nanometer scale (one billionth of a meter).1,2 The nanotechnologyhas grown to multidisciplinary scientific fields in a decade.Nanotechnology has shown huge potential in areas as diverse asdrug development, water decontamination, information and communicationtechnologies, and the production of stronger, lightermaterials and human health care.3,4 Water and air are two vital componentsof life on Earth; the existence of life on Earth is made possiblelargely because is owed by the presence of clean water and air inhabitual form because of their importance to metabolic processeswithin the body. Clean and fresh water and air are essential for thevery existence of life. Contamination of natural water sources bypathogenic microorganisms, heavy metal and groundwater withorganic pollutants are worldwide public health problems, leading towaterborne outbreaks of infectious hepatitis, viral gastroenteritis, andcancer. Other contaminants of water are microorganisms such asEscherichia coli (E. coli), amebas, Cryptosporidium, cholera, viruses,and bacteria.Immobilization of enzymes has been extensively studied for various large-scale applications due to the potential advantages including product purification, catalyst recycling, and continuous operation.The limiting factor of the application of enzyme immobilization is due to the rather poor biocatalytic efficiency of the immobilized enzymes,Therefore, strategies for improving biocatalytic effi-ciency through host materials' structure manipulation are currently being developed; both chemical and physical immobilization pro-cedures have been used for this purpose. Most physical methods are based on entrapment or encapsulation procedures of the bio-logical reagent in nanoporous materials （e.g., mesoporous silica,nanostructured polymers, and sol-gels）. Porous matrices have the capacity to achieve high enzyme loading, but are limited by a high diffusion barrier for the substrate, restricting the accessibility to bioactive sites and affecting the overall effectiveness of the method.On the other hand, covalent attachment is carried out mainly by chemically binding the biocomponents onto the surface of both porous and nonporous materials. Enzymes can undergo covalent modification thrugh attachment of polymers or functional groups on their surface.
