Near Infrared-Emitting Nanoparticles for Biomedical Applications


Book Description

​This book analyzes and evaluates the growing field of light-emitting nanoprobes as contrast agents for in vivo imaging and sensing. It is a comprehensive resource that critically analyzes the state of the art in an interdisciplinary manner, with a special focus on the shift of emission wavelengths into the near-infrared (NIR) spectral region (ranging from 0.7 to 2 microns), which has greatly contributed to the latest advances in biomedical imaging and sensing. This book discusses merits of different contrast agents at nanoscale, and how their unique chemical and structural properties lead to the emission and interaction of light within the NIR window. Both the NIR-emitting materials and various surface modification strategies governing their interactions with the biological system at the “nano” level are discussed. Furthermore, different experimental techniques and protocols for NIR-light-based in vivo imaging and sensing are addressed to shed light on further understanding of the advantages and limitations of each category of these nanoprobes. Assembles the state of the art heretofore appearing in scientific literature into a comprehensive, multi-perspective guidebook on near infrared-emitting nanomaterials in an assortment of biomedical applications; Explains the physical, chemical, and biological phenomena underlying near infrared-emitting nanomaterials for biomedical applications; Presents conceptual and experimental approaches surrounding a unique spectral range of light emission from nanosized contrast agents, while offering a clear explanation of basic and general phenomena regarding the interaction between light and biological tissues, such as absorption, scattering and autofluorescence.

Engineered Near-infrared Nanomaterials for Cancer Theranostics


Book Description

Subsequently, these NIRF nanoparticles were modified to exhibit photothermal properties by integration of either photothermal materials within the NIRF particulate structure. Conventionally used plasmonic photothermal materials due to their size and shape restrictions could not be incorporated in the NIRF nanoparticles. A novel strategy based on interplasmon coupling between sub 4nm gold nanoparticles was developed to overcome this limitation. Surface of NIRF NPs was decorated either externally or internally with small gold nanoparticles in a controlled fashion (surface coverage 6-14%, size 0.7, 1.2, and 3.8nm). The gold speckled silica nanoparticles thus formed exhibited both optical luminescence and photothermal properties. Another strategy to incorporate photothemal properties in NIRF NPs was based on mixed micelles mediated synthesis of organic-inorganic hybrid structures. Molecular photothermal agents such as metal-naphthalocyanine dyes were incorporated inside the pores of NIRF NPs (photothermal: fluorescence dye 4:1). The high optical absorbance cross-section and optical imaging properties of MNPs were utilized for image guided photothermal ablation (tumor necrosis> 90%) of a human breast cancer tumor inside mice.

Infrared Nanophotonics


Book Description

Infrared light radiates from almost all the matter on earth, and its strategic use will be an important issue for the enhancement of human life and the sustainable development of modern industry. Since its frequency is in the same region as phonons or molecular vibrations of materials, measuring its emission or absorption spectra helps us in characterizing and identifying materials in a non-destructive manner. Meanwhile, if we can spectroscopically design infrared emission by tuning chemical composition or artificially controlling nano- to mesoscale structures, this will have a great impact on industrial applications, such as thermophotovoltaics, energy-saving drying furnaces, spectroscopic infrared light sources, and various types of infrared sensors. In this Special Issue, we encourage submissions from researchers who are working on infrared nanophotonics based on MEMS/NEMS, and nanomaterials science, ranging from materials synthesis, to device fabrications, electromagnetic simulations, and thermal managements. Important topics of growing interest are wavelength-selective infrared emitters and detectors, where we can see rapid development in the fields of nano-plasmonics and metamaterials, and we invite such topics for inclusion in this Special Issue. We also encourage submissions on nano-materials science such as on graphene-based infrared detectors/emitters, and nanostructured narrow-band gap semiconductors.
