Nanotechnology future application

In conclusion, the potential of soluble, nanosized metallodendrimers as catalysts in homogeneous reactions is well-consolidated. Future applications of these species are foreseen in high-tech nanotechnology applications in the fields of nano- and microreactors, cascade catalysis, and catalytic biomonitoring and biosensing. In this respect, the recent use of noncovalent strategies for the construction of multicomponent catalytic assemblies, and the use of biomacromolecules within dendritic structures is intriguing [60-62,92,93].

The wide spectrum of self-assembly phenomena can be categorized in various ways. In this entry, we discuss the similarities and the differences between two- and three-dimensional systems. The last section of this entry describes recent and possible future applications of self-assembly processes, mainly related to advanced materials, environmental issues, biotechnology, and nanotechnology. Emulsions, microemulsions, and foams are examples of important and common applications in which self-assembly plays a key role. These have a wide variety of industry applications from cosmetics, foods, detergents, oil recovery, drug formulation/delivery, petroleum refining, and mining. As these are the subjects of other topics in this encyclopedia, they are not covered here.

Fig. 2 Future applications of DNA nanotechnology, (a) A guest in a simple cubic lattice. The DNA lattice is drawn as a portion of simple cubic lattice made from 6-arm junctions. The guests are represented by the kidney-bean-shaped features in every unit cell, (b) DNA as scaffolding. Two branched junctions are shown, and a molecular wire is attached to them. When the two junctions cohere with each other, so does the molecular wire, which forms a synapse. View this art in color at www. dekker.com.)...

This book will focus on a subfield of bionanotechnology and nanomedicine, nanotechnology-enhanced orthopedic materials, which is a specific interdisciplinary area of chemistry, physics, materials sciences, and orthopedics. This book will deliver a comprehensive overview of the field, infused with both great opportunities and challenges, with a particular interest in the fabrications, modifications, and applications of these materials. Furthermore, the book will explore novel nanomaterials with great potential for future applications, as well as the rationale and methodology of applying such materials for orthopedic purposes. 

The main reason for the recent popularity of nanotechnology is that the reduction of the dimensions of a material to nanosize leads to new specific properties [82]. Carbon nanofibers have very high tensile strength and Yormg s modulus (can reach values of about 12,000 MPa and 600 GPa respectively) which are approximately 10 times that of steel. Besides mechanical strength, CNFs are attractive in electrical applications as well due to their high electrical conductivity. These CNF properties provide a huge number of opportunities for future applications in all spheres of life [95]. 

The broad field of the exciting and attractive future applications of DNDs documents that this unique material possesses all the possibilities to become an important part for future nanotechnology advancements. 

Researchers in the field have overcome many of the limitations for real-life applications, but there are many others that are still to be overcome, specifically the stability of the biocatalyst, the biocompatibility of the materials and the products, the chemical and mechanical stability of the electrode materials, the electrolytic solution, and the packaging of the device. Recent advances in nanotechnology have brought great improvements to the development of composite nanomaterials that are feasible to be integrated into BFC designs. Better understanding of the enzymatic systems and processes certainly helped the development of biosensors and made us envision close future applications of BFCs for biomedical purposes. Furthermore, new alternatives for ex vivo applications of biodevices may be implemented in a shorter period of time. 

The unique power of synthesis is the ability to create new molecules and materials with valuable properties. This capacity can be used to interact with the natural world, as in the treatment of disease or the production of food, but it can also produce compounds and materials beyond the capacity of living systems. Our present world uses vast amounts of synthetic polymers, mainly derived from petroleum by synthesis. The development of nanotechnology, which envisions the application of properties at the molecular level to catalysis, energy transfer, and information management has focused attention on multimolecular arrays and systems capable of self-assembly. We can expect that in the future synthesis will bring into existence new substances with unique properties that will have impacts as profound as those resulting from syntheses of therapeutics and polymeric materials.
