Gold nanorods (GNRs) due to their tunable optical properties within the near infrared (NIR) region have been identified as strong candidates for new nano-based biomedical applications. Unfortunately, many have reported GNR cytotoxicity and it is still unclear how GNR aspect ratio (AR), surface charge and surface chemistry contribute to cellular association and cytotoxicity. GNR surface chemistry modifications have been reported to reduce cytotoxicity, however they can result in poor cellular uptake and loss of NIR optical properties preventing efficiency with bio-imaging and photo-thermal applications. The aim of this study was to determine if manipulation of GNR physicochemical properties could enhance biocompatibility while maintaining cellular uptake and preserving NIR optical properties for bio-imaging and plasmonic photo therapeutic applications. This study showed that surface chemistry is primarily responsible for cytotoxicity and cellular association of GNRs. In addition, tannic acid (TA) coated 11-mercaptoundecyl trimethylammonium bromide (MTAB) GNRs (MTAB-TA) displayed enhanced biocompatibility while maintaining high cellular uptake with preserved NIR optical properties, in vitro. Finally, MTAB-TA GNRs demonstrated significantly greater two photon luminescence microscopy image intensity and photo-thermal cellular ablation compared to bare MTAB GNRs. These findings identify MTAB-TA GNRs as prime candidates for use in nano-based bio-imaging and photo-thermal applications.

In this book Andreas Dahlin has written a comprehensive and thorough review of plasmonic biosensors that operate by refractometric detection. After an introductory chapter on biosensors, in which he sets out the concepts of biosensing in its application to such areas as proteomics, medical diagnostics and environmental control, he undertakes an integrated coverage of surface chemistry, surface physics and optics, specifically related to the requirements of design of a plasmonic biosensor. Sections on nanoparticle plasmons and surface plasmons follow, leading to a review of SPR technology for biosensing. The optical properties of nanoholes in metal films and other more complicated plasmonic nanostructures are also briefly discussed. Later chapters discuss experimental plasmon spectroscopy and spectral analysis while the final sections discuss topics such as sensor response and the extent to which quantitative measurements can be made. The book introduces a few relatively controversial opinions on some open questions, such as how best to define sensor performance and the practical use of highly miniaturized sensors. Each of the chapters is extensively referenced and contains appropriate illustrations. The book contains a wealth of information that will be highly beneficial to both existing and new users of refractometric sensing techniques in life science research. It will be a valuable resource for post-graduate research students, academic researchers and those working in industry.

Discover how metal-enhanced fluorescence is changing traditional concepts of fluorescence This book collects and analyzes all the current trends, opinions, and emerging hot topics in the field of metal-enhanced fluorescence (MEF). Readers learn how this emerging technology enhances the utility of current fluorescence-based approaches. For example, MEF can be used to better detect and track specific molecules that may be present in very low quantities in either clinical samples or biological systems. Author Chris Geddes, a noted pioneer in the field, not only explains the fundamentals of metal-enhanced fluorescence, but also the significance of all the most recent findings and models in the field. Metal-enhanced fluorescence refers to the use of metal colloids and nanoscale metallic particles in fluorescence systems. It offers researchers the opportunity to modify the basic properties of fluorophores in both near- and far-field fluorescence formats. Benefits of metal-enhanced fluorescence compared to traditional fluorescence include: Increased efficiency of fluorescence emission Increased detection sensitivity Protect against fluorophore photobleaching Applicability to almost any molecule, including both intrinsic and extrinsic chromophores Following a discussion of the principles and fundamentals, the author examines the process and applications of metal-enhanced fluorescence. Throughout the book, references lead to the primary literature, facilitating in-depth investigations into particular topics. Guiding readers from the basics to state-of-the-technology applications, this book is recommended for all chemists, physicists, and biomedical engineers working in the field of fluorescence.
