Available in PDF, EPUB and Kindle. Book excerpt: Cancer is a disease in which biological cells grow uncontrollably and spread to other organs of a patient. Cancer disease comprises of abnormal cells, which can develop in any part of the human body. Normally, cells grow and multiply in a controlled manner, and when these become old or damaged, then cells die i.e., known as programmed cell death or apoptosis. Sometimes this controlled process of cell growth or death breaks down and there is abnormal growth of cells which form tumors in the body. The tumor cells grow slowly and do not spread in the body are known as benign (noncancerous) tumors. When tumor cells grow rapidly, these spread throughout the body and are called malignant tumors (cancerous). While there is no one specific cause of cancer, factors such as smoking, excessive UV exposure from the sun or tanning beds, being overweight or obese, and excessive alcohol use can all contribute to the formation of cancerous cells in the body. A few emerging techniques such as immunotherapy, radio-frequency ablation, thermal ablation, cryotherapy, photodynamic therapy and plasmonic photothermal therapy, show higher efficacy and long survival rates as compared to the conventional methods. Nanoparticles (1-100 nm in size) offer a biocompatible and biodegradable platform for cancer diagnosis as a contrast agent and as a cancer treatment through nanoparticle based thermal ablation or delivery of conventional chemotherapeutic drugs. The light interaction of biological tissue provides a basis for a wide variety of biomedical applications, like non-invasive diagnosis (tumor detection, contrast microscopy, optical coherence tomography, etc.), treatment (laser surgery, photodynamic therapy, photothermal therapy, etc.), and monitoring of bio-parameters (pulse oximetry, glucose monitoring, etc.). The thermal ablation of the tumor by using light interaction of metallic nanoparticles is known as plasmonic photothermal interaction. This allows for tumor treatment with minimal side effects on nearby healthy tissue. This technique is critically governed by the optical characteristics of tissue as well as the variations in the properties during the interaction of light with the nanoparticles or tissue. For example, the efficacy of cancer treatment by plasmonic photothermal therapy mainly depends upon the light absorption by tumor cells and/or nanoparticles. Therefore, it is important to characterize the optical characteristics of tissue, especially in the presence of nanoparticles and at different stages of photothermal therapy for pre-treatment planning as well as improving the efficacy of the therapy.

Download or read book Hybrid Systems of Plasmonic Nanostructures and Functional Materials for Light matter Interactions and Active Plasmonic Devices written by Mingson Wang (Ph. D.) and published by . This book was released on 2018 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in nanofabrication and characterization of nanomaterials enable the development of plasmonic nanostructures with unique optical properties. Plasmonic nanostructures have been extensively studied for their potential applications in optical sensing, photothermal therapy, photovoltaics, and photocatalysis. In this dissertation, we present studies of light-matter interactions in hybrid systems consisting of plasmonic nanostructures and functional materials. These studies are focused on four major types of light-matter interactions in plasmonic nanostructures: (1) plasmon-induced resonance energy transfer (PIRET); (2) plasmon-enhanced spontaneous emission; (3) Fano interference between plasmonic nanostructures and emitters; and (4) strong plasmon-exciton coupling. We also achieved the tuning of light-matter interactions by modifying the physical properties of functional materials or plasmonic nanostructures. In addition, the active control of light-matter interactions was demonstrated by integrating plasmonic nanostructures with switchable materials, such as photochromic dyes. Specifically, we first demonstrated the blue-shifted PIRET from a single gold nanorod (AuNR) to dye molecules. AuNRs enable the energy transfer from plasmonic donors to dye acceptors with light having a longer wavelength and lower intensity, compared to dye donors. Secondly, we studied the tuning of plasmon-trion and plasmon-exciton resonance energy transfer from a single gold nanotriangle (AuNT) to monolayer MoS2. We achieved these phenomena by the combination of rationally designed monolayer MoS2-plasmonic nanoparticle hybrid systems and single-nanoparticle measurements. Thirdly, we realized the large modulation of hybrid plasmonic waveguide mode (HPWM) in single hybrid molecule-plasmon nanostructures through the strong molecule-plasmon coupling. The HPWM features both the capacity of plasmonic nanostructures to manipulate light at the nanoscale and the low loss of dielectric waveguides. Fourthly, we demonstrated the photoswitchable plasmon-induced fluorescence enhancement. This large switchable modulation of fluorescence was derived from the large near-field enhancement at the subnanometer gap between Au nanoparticles and switchable intersystem crossing as a nonradiative decay channel in photochromic dyes. Finally, we achieved tunable Fano resonances and plasmon-exciton coupling in two-dimensional (2D) WS2-AuNT hybrid structures at room temperature. The tuning of Fano resonances and plasmon-exciton coupling were achieved by the active control of the WS2 exciton binding energy and dipole-dipole interaction through controlling the dielectric constant of the surrounding medium.
