Cancer is a complex disease that is characterized by cell proliferation (uncontrolled cell division), cell transformation and an escape from apoptosis and these properties pave the way for invasion, angiogenesis and metastasis. Additionally, cancer has also emerged as a major public health problem in developing countries. According to the World Health Organization, new cases of cancer impairment will increase with estimated death rates of up to 11 million in the year 2030. Although in recent decades much progress has been achieved in respect of therapies, like surgery, chemotherapy, radiation or hormone ablation therapy, they are not successful in more than 50% of cases. Furthermore, for those who survive the risk of reoccurrence of the disease is a major problem. Breast cancer is one of the most prevalent malignancies among women worldwide. The existing therapeutic agents for breast cancer produce several side effects. Development of specifically breast cancer cell targeting drug without any side effect to normal cells is an ongoing effort in the field of cancer drug discovery. Cytotoxic chemotherapy plays a vital role in the management of patients.
The organic compounds that emit at different wavelength regions have been selected to study. Fluorescent dyes play an important role for staining and sensoring in analytical chemistry, environmental science, biology and medicine. Some fluorescent dyes are laser active and are used in dye lasers. In recent years the research interests changed from liquid dye lasers to solid state dye lasers.Often organic polymers are used as solid matrices for organic dyes. Semiconducting (conjugated) polymers have properties that make them attractive as the gain material for solid state lasers. Dye lasers utilizing a solid host are very attractive for a wide range of applications. For example, in medicine can use in cardiology for ablation of blood clots, photodynamic therapy for photo-radiation and bio-stimulation, biological field DNA detection and sequencing, remote sensing of atmospheric contaminants, underwater communications, holography, optoelectronic applications.
This book is mostly concerned on the experimental research of the nonlinear optical characteristics of various media, low- and high-order harmonic generation in different materials, and formation, and nonlinear optical characterization of clusters. We also demonstrate the inter-connection between these areas of nonlinear optics.Nonlinear optical properties of media such as optical limiting can be applied in various areas of science and technology. To define suitable materials for these applications, one has to carefully analyse the nonlinear optical characteristics of various media, such as the nonlinear refractive indices, coefficients of nonlinear absorption, saturation absorption intensities, etc. Knowing the nonlinear optical parameters of materials is also important for describing the propagation effects, self-interaction of intense laser pulses, and optimisation of various nonlinear optical processes. Among those processes one can admit the importance of the studies of the frequency conversion of coherent laser sources. The area of interest for nonlinear optical characterization of materials is also closely related with new field of nanostructures formation and application during laser-matter interaction.We show how the nonlinear optical analysis of materials leads to improvement of their high-order nonlinear optical response during the interaction with strong laser fields. Ablation-induced nanoparticles formation is correlated with their applications as efficient sources of coherent short-wavelength photons. From other side, recent achievements of harmonic generation in plasmas are closely related with the knowledge of the properties of materials in the laser plumes. All of these studies are concerned with the low-order nonlinear optical features of various materials. The novelty of the approach developed in present book is related with inter-connection of those studies with each other.
The pulsed laser ablation in liquid media (PLAL) is a rapidly emerging technique in material science for fabricating metal and metal-oxide nanoparticles. The advantage of this method over the conventional chemical methods is the lower cost, high purity and absence of defects in the formed nanoparticles (NPs). The technique requires the minimum amount of chemical species for synthesis compared to the conventional chemical process and provides greater flexibility in controlling the properties of NPs by suitable choice of laser parameters and liquid medium. This work discuss effect of various laser parameters, surrounding liquid and surfactants on synthesized metal oxide nanostructures. Different approaches to extend PLAL technique to multicomponent material fabrication has been discussed. These multicomponent nanocomposites exhibit modified optical properties, enhanced stability and functionalities.
Since the discovery of carbon nanotubes by Sumio Iijima, an intensive research on carbon materials has been carried out. Carbon nanotubes and carbon nanofibers have drawn much attention due to their electronic and mechanical properties. However, because of low production capacity and high production costs at present, their applications cannot be extended until large-scale production is realized. Among the many synthetic methods, chemical vapor deposition method has advantages of high yield, high selectivity and low cost over traditional physical ones such as laser ablation and arc-discharge. High yield synthesis of one dimensional carbon nanostructures is essential for applications. In this book, an economical and environmental friendly route for the scalable production of CNTs and CNFs on easy soluble support has been discussed. The use of synthesized carbon nanotubes as catalyst support for oxidation of alcohols by Schiff base complexes and also as hydrogen storage materials is discussed in detail.
