Book Description

In the past few years, growing attention has been devoted to the study of the interactions taking place in mixed systems of phospholipid membranes and inorganic nanoparticles. This is an important issue with regard to using nanoparticles in nanomedicine but also in the related field of nanotoxicology. However, the nature of the interactions in such mixtures is rather complex and may lead to the formation of different colloidal structures. Focusing on the case of liposomes and silica nanoparticles, the study presented here aims at improving our understanding of the interactions in such mixed systems and at obtaining a detailed picture of the hybrid structures they result in. Drawing a parallel between different systems, this work offers not only interesting features on the internalization process of nanoparticles and on the stability of nanoparticle–decorated vesicles but also comprehensive insights into the influence of the bilayer state (liquid, gel) on the nanoscale structures of hybrid liposome/nanoparticle complexes.

Book Description

This book provides systematic knowledge of basic principles in the design of fluorescence sensing and imaging techniques together with critical analysis of recent developments. Fluorescence is the most popular technique in chemical and biological sensing because of its ultimate sensitivity, high temporal and spatial resolution and versatility that enables imaging within the living cells. It develops rapidly in the directions of constructing new molecular recognition units, new fluorescence reporters and in improving sensitivity of response up to detection of single molecules. Its application areas range from control of industrial processes to environment monitoring and clinical diagnostics. Being a guide for students and young researchers, it also addresses professionals involved in active basic and applied research. Making a strong link between education, research and product development, this book discusses prospects for future progress.

Book Description

In recent years, the fabrication of nanomaterials and exploration of their properties have attracted the attention of various scientific disciplines such as biology, physics, chemistry, and engineering. Although nanoparticulate systems are of significant interest in various scientific and technological areas, there is little known about the safety of these nanoscale objects. It has now been established that the surfaces of nanoparticles are immediately covered by biomolecules (e.g. proteins, ions, and enzymes) upon their entrance into a biological medium. This interaction with the biological medium modulates the surface of the nanoparticles, conferring a “biological identity” to their surfaces (referred to as a “corona”), which determines the subsequent cellular/tissue responses. The new interface between the nanoparticles and the biological medium/proteins, called “bio-nano interface,” has been very rarely studied in detail to date, though the interest in this topic is rapidly growing. In this book, the importance of the physiochemical characteristics of nanoparticles for the properties of the protein corona is discussed in detail, followed by comprehensive descriptions of the methods for assessing the protein-nanoparticle interactions. The advantages and limitations of available corona evaluation methods (e.g. spectroscopy methods, mass spectrometry, nuclear magnetic resonance, electron microscopy, X-ray crystallography, and differential centrifugal sedimentation) are examined in detail, followed by a discussion of the possibilities for enhancing the current methods and a call for new techniques. Moreover, the advantages and disadvantages of protein-nanoparticle interaction phenomena are explored and discussed, with a focus on the biological impacts.

Book Description

Nanotechnology is an interdisciplinary research field that integrates chemistry, engineering, biology, and medicine. Nanomaterials offer tremendous opportunity as well as challenges for researchers. Of course, cancer is one of the world's most common health problems, responsible for many deaths. Exploring efficient anticancer drugs could revolutionize treatment options and help manage cancer mortality. Nanomedicine plays a significant role in developing alternative and more effective treatment strategies for cancer theranostics. This book mainly focuses on the emerging trends using nanomaterials and nanocomposites as alternative anticancer material’s. The book is divided into three main topic areas: how to overcome existing traditional approaches to combat cancer, applying multiple mechanisms to target the cancer cells, and how nanomaterials can be used as effective carriers. The contents highlight recent advances in interdisciplinary research on processing, morphology, structure, and properties of nanostructured materials and their applications to combat cancer.Cancer Nanotheranostics is comprehensive in that it discusses all aspects of cancer nanotechnology. Because of the vast amount of information, it was decided to split this material into two volumes. In the first volume of Cancer Nanotheranostics, we discuss the role of different nanomaterials for cancer therapy, including lipid-based nanomaterials, protein and peptide-based nanomaterials, polymer-based nanomaterials, metal-organic nanomaterials, porphyrin-based nanomaterials, metal-based nanomaterials, silica-based nanomaterials, exosome-based nanomaterials and nano-antibodies. In the second volume, we discuss the nano-based diagnosis of cancer, nano-oncology for clinical applications, nano-immunotherapy, nano-based photothermal cancer therapy, nano-erythrosomes for cancer drug delivery, regulatory perspectives of nanomaterials, limitations of cancer nanotheranostics, the safety of nano-biomaterials for cancer nanotheranostics, multifunctional nanomaterials for targeting cancer nanotheranostics, and the role of artificial intelligence in cancer nanotheranostics.

We can use the short text on the SI page for the description, or you make slight modifications on it. The description/summary is only for promotion (flyer, distribution channels), and will not be included in the book You can use the short text on the SI page for the description Nanovesicles are highly-promising systems for the delivery and/or targeting of drugs, biomolecules and contrast agents. Despite the fact that initial studies in this area were performed on phospholipid vesicles, there is an ever-increasing interest in the use of other molecules to obtain smart vesicular carriers focusing on strategies for targeted delivery. These systems can be obtained using newly synthesized smart molecules, or by intelligent design of opportune carriers to achieve specific delivery to the site of action. The drug/contrast agent-containing vesicles need to be directed to precise locations within the body to obtain desired magnitude and duration of the therapeutic or diagnostic effect. This spatial control in the delivery might open new avenues to modulate drug activity while avoiding side-effects and to optimize contrast agent properties while avoiding a broad distribution in the organism. However, delivering and targeting active substances into specific tissues and cells is still a challenge in designing novel therapeutic approaches against untreatable disorders, such as tumors and degenerative diseases.
