Nanotechnology, Metal Nanoparticles, and Biomedical Applications of Nanotechnology

Abstract: Nanotechnology has emerged as an important field of modern scientific research due to its diverse range of applications in the area of electronics, material sciences, biomedical engineering, and medicines at nano levels such as healthcare, cosmetics, food and feed, environmental health, optics, biomedical sciences, chemical industries, drug-gene delivery, energy science, optoelectronics, catalysis, reprography, single electron transistors, light emitters, nonlinear optical devices, and photoelectrochemical applications and other applications. Due to these immense applications of nanotechnology in biomedical science, it has became possible to design the pharmaceuticals in such a way that they could directly treat diseased cells like cancer and make microscopic repairs in hard-to-operate-on areas of the body. The nanomachines have been designed to clean up toxins or oil spills, recycle all garbage, eliminate landfills, etc. The chapter summarizes the present and future applications of nanotechnology for human welfare but needs further study in catalysis, optical devices, sensor technology, cancer treatment, and drug delivery systems.

Advances in Nano Biotechnology

Abstract: Nanobiotechnology, bionanotechnology, and nanobiology are terms that refer to the intersection of nanotechnology and biology. This discipline helps to indicate the merger of biological research with various fields of nanotechnology. Concepts that are enhanced through nanobiology include: nanodevices (such as biological machines), nanoparticles, and nanoscale phenomena that occurs within the discipline of nanotechnology. This technical approach to biology allows scientists to imagine and create systems that can be used for biological research. In the present book, fifteen typical literatures about Nano Biotechnology published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on material science, biology, technology, ect. We hope this book can demonstrate advances in Nano Biotechnology as well as give references to the researchers, students and other related people.

Biogenic metal sulfide nanoparticles synthesis and applications for biomedical and environmental technology

Abstract: Biogenic nano-synthesis includes synthesizing nanotubes or nanostructured materials using biological sources or green technologies, like those containing microbes, plants, and viruses or their by-products, which including proteins and lipids, using multiple biotechnological techniques. Nanocomposites produced by renewable technology are often much greater than those generated by physical and chemical multiaspect methods. Green methods, for example, reduce the usage of expensive additives, consume fewer resources, and manufacture environmentally benign materials and by-products. Green nanobiotechnology is thus a successful alternative route to the development of biocompatible stable nanoparticles. In this study, we present the numerous biogenic metal sulfides, their characterization techniques, and biomedical and environmental technology applications.

Biolithography: a tool to manipulate surfaces for DNA-assisted patterning in the micron- and nanorange

Abstract: On the way to make personalized medical care accessible to a large number of people, many hindrances need to be overcome. Biosensors, consisting of active areas in a noninteracting background, are a crucial technology for which researches are seeking. The permanent update of the patients conditions e.g., the early detection of cancer, requires a fast, sensitive and selective analysis of a blood sample. We gained more insight into the human genome and genetic mutations in healthy and diseased tissue through the DNA microarray technology. However, proteins, not only genes, provide information about a course of disease and the potential therapy. Furthermore, membrane proteins are the targets for more than 60 % of todays therapeutic drugs. The direct application of the DNA microarray technology to proteins is challenging, especially when membrane proteins are involved as these are prone to denaturation and loss of activity upon removal from their natural environment, the lipid membrane. Although fluorescence as an analytical tool is well-established and widely used in biology, it suffers from the fact, that the dyes bleach upon exposure to light and the biomolecules need to be chemically modified in order to label them. Nowadays, the expectations, that medical care can profit from nanotechnology, are high. On the one hand higher density of active spots on the surface, hence a higher throughput of more target molecules, might be feasible. On the other hand, novel sensing approaches, among them the electrical nanowire-based biosensing, the electrical sensing of ion channels positioned on nanopores/grooves, and the optical sensing based on nobel metal colloids are potential approaches where biotechnology could benefit from nanotechnology. Although the search for always smaller and faster devices is a central issue, there are still many open questions which can be addressed via microtechnology when the creation of oriented tissue and organs is of interest. Moreover, there is a need to locally in situ manipulate structured surfaces in the micron and in the nanorange, without the need of
