This book documents the tremendous progress in the use of nanotechnology for a range of bioapplications with the aim of providing students, researchers, technicians, and other professionals with an up-to-date overview of the field. After a general introduction to the surface modifications of nanoparticles required for different biological applications, and to the properties of the modified nanoparticles, a series of chapters describe the state of the art in respect of different types of nanoparticle, including silica nanoparticles, fluorescent nanomaterials, metal nanoparticles, magnetic nanoparticles, carbon-based nanostructures, and other novel nanomaterials. Detailed information is supplied on methods of preparation, chemical and physical properties, and current and potential applications. The closing chapters discuss lithography methods for the top-down approach to nanoparticle synthesis and the use of spectroscopic studies as a tool for the characterization of each nanoparticle. Future prospects and challenges for the development of further nanomaterials with bioapplications are also covered.
This unique volume provides a broad introduction to plasmon resonances in nanoparticles and their novel applications. Here, plasmon resonances are treated as an eigenvalue problem for specific boundary integral equations and general physical properties of plasmon spectrum are studied in detail. The coupling of incident radiation to specific plasmon modes, the time dynamics of their excitation and dephasing are also analytically treated. Finally, the applications of plasmon resonances to SERS, light controllability (gating) of plasmon resonances in semiconductor nanoparticles, the use of plasmon resonances in thermally assisted magnetic recording (TAMR), as well as in all-optical magnetic recording and for enhancement of magneto-optic effects are presented.
Nanoparticles with their unique properties are interesting building blocks for the construction of new nanomaterials. By controlling the composition as well as the structure of these nanoparticle-based materials, novel properties can emerge. In this thesis, a new type of protein-based materials was realized by using an innovative design approach with two oppositely charged ferritin protein containers as template for the precise positioning of the nanoparticles. Nanoparticle incorporation inside the protein container cavity was performed by encapsulation of surface functionalized gold nanoparticles with a dis- and reassembly approach or synthesis of metal oxide nanoparticles in situ inside the protein container cavity. The crystallization of oppositely charged protein containers with nanoparticle cargo yielded highly ordered nanoparticle superlattices as free-standing crystals, with up to a few hundred micrometers in size. Structural studies and characterization of optical as well as catalytic properties of the binary crystals were performed. Because the protein scaffold is independent of the nanoparticle cargo, this modular approach will enable tuning of the material properties by choice of nanoparticle content, assembly type and protein container type.

Plasmonic Sensors and their Applications A practically-focused reference and guide on the use of plasmonic sensing as a faster and cheaper alternative to conventional sensing platforms Plasmons, the collective oscillations of electrons occurring at the interface between any two materials, are sensitive to changes in dielectric properties near metal surfaces. Plasmonic sensors enable the real-time study of unique surface properties by monitoring the effect of the material interaction at the sensor surface. Plasmonic sensing techniques offer fast, label-free analysis, and hold advantages over labelling techniques such as ELISA (enzyme-linked immunosorbent assay). Plasmonic Sensors and their Applications examines the development and use of highly sensitive and selective plasmonic sensing platforms in chemistry, biotechnology, and medicine. Contributions by an international panel of experts provide timely and in-depth coverage of both real-world applications and academic research in the dynamic field. The authors describe advances in nanotechnology, polymer chemistry, and biomedicine, explore new and emerging applications of plasmonic sensing, discuss future trends and potential research directions, and more.

World Scientific Reference on Plasmonic Nanomaterials: Principles, Design and Bio-applications is a book collection that encompasses multiple aspects of the exciting and timely field of nanoplasmonics, under the coordination of international plasmonic nanomaterials expert, Dr Luis Liz-Marzán. Plasmonics has a long history, from stained glass in ancient cathedrals, through pioneering investigations by Michael Faraday, all the way into the nanotechnology era, where it blossomed into an extremely active field of research with potential applications in a wide variety of technologies.Given the breadth of the materials, phenomena and applications related to plasmonics, this Reference Set offers a collection of chapters within dedicated volumes, focusing on the description of selected phenomena, with an emphasis in chemistry as an enabling tool for the fabrication of, often sophisticated, plasmonic nanoarchitectures and biomedicine as the target application.Basic principles of surface plasmon resonances are described, as well as those mechanisms related to related phenomena such as surface-enhanced spectroscopies or plasmonic chirality. Under the guidance of theoretical models, wet chemistry methods have been implemented toward the synthesis of a wide variety of nanoparticles with different compositions and tailored morphology. But often the optimal nanoarchitecture requires post-synthesis treatments, including functionalization of nanoparticle surfaces, application of external stimuli toward self-assembly into well-defined supraparticle structures and so-called supercrystals. All such nanomaterials can find applications in various biomedical aspects, most often in relation to diagnosis, through either the detection of disease biomarkers at extremely low concentrations or the design of bioimaging methods for in vivo monitoring. Additionally, novel therapeutic tools can also profit from plasmonic nanomaterials, such as photothermal therapy or nanocatalysis.The reference set thus offers comprehensive information of an extremely active subset within the world of plasmonic nanomaterials and their applications, which aims at not just collecting existing knowledge but also promoting further research and technology transfer into the market and the clinic.
