This book focuses on the application of nanotechnology in medicine and drug delivery, including diagnosis and therapy. Nanomedicine can contribute to the development of a personalized medicine both for diagnosis and therapy. By interacting with biological molecules at nanoscale level, nanotechnology opens up an immense field of research and applications. Interactions between artificial molecular assemblies or nanodevices and biomolecules can be understood both in the extracellular medium and inside human cells. Operating at nanoscale allows exploitation of physical properties different from those observed at microscale, such as the volume to surface area ratio. A number of clinical applications of nanobiotechnology, such as disease diagnosis, target-specific drug delivery, and molecular imaging are being investigated. Some promising new products are also undergoing clinical trials. Such advanced applications of this approach to biological systems will undoubtedly transform the foundations of diagnosis, treatment, and prevention of disease in the future. Nanomedicine sales reached $16 billion in 2015, with a minimum of $3.8 billion in nanotechnology R&D being invested each year. Global funding for emerging nanotechnology increased by 45% per year in recent years, with product sales exceeding $1 trillion in 2013. As the nanomedicine industry continues to grow, it is expected to have a significant impact on the global economy. This book provides clear, colorful and simple illustrations, tables, and case studies to clearly convey the content to a general audience and reader. This book also discusses the development of nanobiomaterials from biogenic (biological sources) systems for healthcare and disease therapies. This book, therefore, is useful for researchers and academicians in the fields of nanotechnology, medicine, nano-biotechnology and pharmacology.

The generation of well-defined nanoparticles of excellent size and shape involves physical and chemical methodologies that are complicated, expensive, and produce hazardous toxic waste that is harmful to the environment and to human health. In order to combat the disadvantages of these methods, scientists have created “the biological method,” a new synthetic methodology that serves as a proper alternative to physical and chemical methodologies because of its easy utility, low cost, rapid synthesis, controlled size characteristics, controlled toxicity, and eco-friendliness. Nanobiotechnology is the science in which living matter can be manipulated and exploited to produce materials within the nano-scale. It is a multidisciplinary field of science framed by biology, chemistry, engineering, materials, and life sciences. Different biological entities can be exploited to yield biologically synthesized nanomaterials including bacteria, actinomycetes, yeast, fungi, viruses, algae, plant extracts, and agro-industrial waste extracts. This book represents a comprehensive review concerning the state of the art in nanobiotechnology, emphasizing the use of diverse biological entities in the science, and its versatile applications. It describes currently existing methodology with the latest published references, and provides safety information. It serves as the ideal guide for scientists interested in exploring nanobiotechnology.

Nanotechnology is an important field of the modern research dealing with synthesis and manipulation of the structure of matter ranging from approximately 1 to 100 nm in size, commonly called nanomaterials. Nanoparticles can be prepared through a variety of physical and chemical processes which are costly and affect the environment. Phytonanotechnology emerges as a method of green synthesis in which plants are used for the synthesis of nanoparticles, as a technology that respects the environment. The noble metal nanoparticles show unique and considerably different physical and chemical properties compared to their macro scaled counterparts. Silver is one of the noble metals with antimicrobial activity and lower toxicity for animal cells. Due to their potential application in human and animal medicine for treating skins fungal infections, interest in silver nanoparticles (AgNP) have been increased in the last years. Yeasts of Malassezia genus are considered etiological agent of pityriasis versicolor and Malassezia folliculitis, associated agents in seborrheic dermatitis/dandruff and a contributory factors to exacerbate other skin disorders.Objectives of this work were to obtain AgNP by chemical and green synthesis and to study its in vitro antifungal activity against clinical isolates of Malassezia furfur.Chemical synthesis of nanoparticles (AgNP-CS) was performed by chemical reduction of AgNO3 in ethanol according to Roldu00e1n et al., (2008). An aqueous leaf extract of Acanthospermum australe (Loefl.) Kuntze, was used for the green synthesis (AgNP-GS), according to Song et al., (2009) with modifications.In order to evaluate the inhibitory activity of both AgNP synthesized, the minimum inhibitory concentrations (MIC) against 22 clinical isolates and a reference strain of M. furfur were determined by broth microdilution method in accordance with CLSI M27-A3 with the modifications proposed by Rojas et al., (2014). Range, arithmetic mean, mode, MIC50 and MIC90 values defined as the lowest concentration at which 90 and 50% of the isolates were inhibited, were also obtained.AgNP-CS against M. furfur showed values ranged 0.12-2 u03bcg/mL; arithmetic mean: 0.70 u03bcg/mL; mode: 1 u03bcg/mL; MIC50: 0.50 u03bcg/mL; MIC90: 1 u03bcg/mL. In contrast, AgNP-GS showed range 0.25-8 u03bcg/mL; arithmetic mean: 6.00 u03bcg/mL; mode: 8 u03bcg/mL; MIC50: 8 u03bcg/mL and MIC90: 8 u03bcg/mL.M. furfur showed a diverse susceptibility profiles against AgNP obtained by chemical and green synthesis. AgNP-CS was more active than AgNP-GS, showing lower variability among different isolates. However, it should be taken into account that the green synthesis of nanoparticles is a less expensive method with the important advantage related to the care of the environment.

This book sheds new light on the role of various environmental factors in regulating the metabolic adaptation of medicinal and aromatic plants. Many of the chapters present cutting-edge findings on the contamination of medicinal plants through horizontal transfer, as well as nanomaterials and the biosynthesis of pharmacologically active compounds. In addition, the book highlights the impacts of environmental factors (e.g., high and low temperature, climate change, global warming, UV irradiation, intense sunlight and shade, ozone, carbon dioxide, drought, salinity, nutrient deficiency, agrochemicals, waste, heavy metals, nanomaterials, weeds, pests and pathogen infections) on medicinal and aromatic plants, emphasizing secondary metabolisms. In recent years, interest has grown in the use of bioactive compounds from natural sources. Medicinal and aromatic plants constitute an important part of the natural environment and agro-ecosystems, and contain a wealth of chemical compounds known as secondary metabolites and including alkaloids, glycosides, essential oils and other miscellaneous active substances. These metabolites help plants cope with environmental and/or external stimuli in a rapid, reversible and ecologically meaningful manner. Additionally, environmental factors play a crucial role in regulating the metabolic yield of these biologically active molecules. Understanding how medicinal plants respond to environmental perturbations and climate change could open new frontiers in plant production and in agriculture, where successive innovation is urgently needed due to the looming challenges in connection with global food security and climate change. Readers will discover a range of revealing perspectives and the latest research on this vital topic.
