Book excerpt: Nanotechnology offers tremendous potential for use in biomedical applications, including cancer and stem cell imaging, disease diagnosis and drug delivery. The development of nanosystems has aided in understanding the molecular mechanisms of many diseases and permitted the controlled nanoscale manipulation of biological phenomena. In recent years, many studies have focused on the use of several kinds of nanomaterials for cancer and stem cell imaging and also for the delivery of anticancer therapeutics to tumor cells. However, the proper diagnosis and treatment of aggressive tumors such as brain and breast cancer requires highly sensitive diagnostic agents, in addition to the ability to deliver multiple therapeutics using a single platform to the target cells. Addressing these challenges, novel multifunctional nanomaterial-based platforms that incorporate multiple therapeutic and diagnostic agents, with superior molecular imaging and targeting capabilities, has been presented in this work. The initial part of this work presents the development of novel nanomaterials with superior optical properties for efficiently delivering soluble cues such as small interfering RNA (siRNA) into brain cancer cells with minimal toxicity. Specifically, this section details the development of non-toxic quantums dots for the imaging and delivery of siRNA into brain cancer and mesenchymal stem cells, with the hope of using these quantum dots as multiplexed imaging and delivery vehicles. The use of these quantum dots could overcome the toxicity issues associated with the use of conventional quantum dots, enabled the imaging of brain cancer and stem cells with high efficiency and allowed for the delivery of siRNA to knockdown the target oncogene in brain cancer cells. The latter part of this thesis details the development of nanomaterial-based drug delivery platforms for the codelivery of multiple anticancer drugs to brain tumor cells. In particular, this part of the thesis focuses on the synthesis and use of a biodegradable dendritic polypeptide-based nanocarrier for the delivery of multiple anticancer drugs and siRNA to brain tumor cells. The co-delivery of important anticancer agents using a single platform was shown to increase the efficacy of the drugs manyfold, ensuring the cancer cell-specific delivery and minimizing dose limiting toxicities of the individual drugs. This would be of immense importance when used in vivo.

Available in PDF, EPUB and Kindle. Book excerpt: Development of novel imaging probes for cancer diagnosis is critical for early disease detection and management. The past two decades have witnessed a surge in the development and evolution of radiolabeled nanoparticles as a new frontier in personalized cancer nanomedicine. The dynamic synergism of positron emission tomography (PET) and nanotechnology combines the sensitivity and quantitative nature of PET with the multifunctionality and tunability of nanomaterials, which can help overcome certain key challenges in the field. Silica, "generally recognized as safe" (GRAS) by the Food and Drug Administration (FDA) of the United States, has emerged as one of the leading nanomaterials employed for molecular imaging and therapy of a wide variety of diseases, including cancer. However in vivo biodistribution and active targeting of silica-based nanomaterials has remained a relatively under explored area, based mainly on semi-quantitative techniques such as fluorescence imaging. In this dissertation, I explore the concept of radiolabeled silica nanoparticles for vasculature-targeted imaging of different tumor types. Both chelator-based and chelator-free radiolabeling techniques were employed for accurate and quantitative analysis of the in vivo pharmacokinetics of radiolabeled silica nanomaterials. (Chapters 2 and 3) The large surface area, ease of tunability and facile silica chemistry were employed to create multifunctional silica-based materials to simultaneously seek-and-treat cancers, by incorporating multiple components into a single nanoplatform. Photodynamic agent, porphyrin was loaded into the central cavity of hollow mesoporous silica nanoparticles, and the shell was decorated with photothermal nanoparticles, CuS, yielding a multimodal theranostic nanoplatform which could synergistically annihilate the tumor without relapse. (Chapter 4) A major hurdle in the successful clinical translation of nanomaterials is their rapid sequestration by the organs of the reticuloendothelial system (RES), mainly liver and spleen, and prolonged retention in the body, raising long-term toxicity concerns. To combat this issue, two approaches were employed; (i) Synthesis of biodegradable mesoporous silica nanoparticles (Chapter 5), and (ii) development of ultrasmall nanoparticles including renal clearable Au nanoparticles and hepatically cleared ultrasmall mesoporous silica nanoparticles (Chapter 6); for prolonged blood circulation, enhanced tumor uptake and rapid clearance from the body, enabling unprecedented tumor-to-normal tissue contrast. Overall, the reported studies explore the synergism of molecular imaging and therapy, and nanotechnology. While the application of nanomaterials in the former imparts multifunctionality to the molecular agent, allowing multimodal imaging and synergistic therapeutic regimes to be carried out simultaneously; molecular imaging techniques such as PET, allow accurate measurement of the in vivo pharmacokinetics of the nanomaterials, playing a major role towards their successful clinical translation. Further work will be required to better understand the in vivo biodistribution of both biodegradable and ultrasmall nanomaterials, and further employ them for early and specific detection of cancer, effective treatment and monitoring.

Download or read book Cancer Nanotheranostics What Have We Learned So Far written by João Conde and published by Frontiers Media SA. This book was released on 2016-03-17 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: After a quarter of century of rapid technological advances, research has revealed the complexity of cancer, a disease intimately related to the dynamic transformation of the genome. However, the full understanding of the molecular onset of this disease is still far from achieved and the search for mechanisms of treatment will follow closely. It is here that Nanotechnology enters the fray offering a wealth of tools to diagnose and treat cancer. In fact, the National Cancer Institute predicts that over the next years, nanotechnology will result in important advances in early detection, molecular imaging, targeted and multifunctional therapeutics, prevention and control of cancer. Nanotechnology offers numerous tools to diagnose and treat cancer, such as new imaging agents, multifunctional devices capable of overcome biological barriers to deliver therapeutic agents directly to cells and tissues involved in cancer growth and metastasis, and devices capable of predicting molecular changes to prevent action against precancerous cells. Nanomaterials-based delivery systems in Theranostics (Diagnostics & Therapy) provide better penetration of therapeutic and diagnostic substances within the body at a reduced risk in comparison to conventional therapies. At the present time, there is a growing need to enhance the capability of theranostics procedures where nanomaterials-based sensors may provide for the simultaneous detection of several gene-associated conditions and nanodevices with the ability to monitor real-time drug action. These innovative multifunctional nanocarriers for cancer theranostics may allow the development of diagnostics systems such as colorimetric and immunoassays, and in therapy approaches through gene therapy, drug delivery and tumor targeting systems in cancer. Some of the thousands and thousands of published nanosystems so far will most likely revolutionize our understanding of biological mechanisms and push forward the clinical practice through their integration in future diagnostics platforms. Nevertheless, despite the significant efforts towards the use of nanomaterials in biologically relevant research, more in vivo studies are needed to assess the applicability of these materials as delivery agents. In fact, only a few went through feasible clinical trials. Nanomaterials have to serve as the norm rather than an exception in the future conventional cancer treatments. Future in vivo work will need to carefully consider the correct choice of chemical modifications to incorporate into the multifunctional nanocarriers to avoid activation off-target, side effects and toxicity. Moreover the majority of studies on nanomaterials do not consider the final application to guide the design of nanomaterial. Instead, the focus is predominantly on engineering materials with specific physical or chemical properties. It is imperative to learn how advances in nanosystem’s capabilities are being used to identify new diagnostic and therapy tools driving the development of personalized medicine in oncology; discover how integrating cancer research and nanotechnology modeling can help patient diagnosis and treatment; recognize how to translate nanotheranostics data into an actionable clinical strategy; discuss with industry leaders how nanotheranostics is evolving and what the impact is on current research efforts; and last but not least, learn what approaches are proving fruitful in turning promising clinical data into treatment realities.

Book excerpt: Molecular imaging, the "visualization, characterization, and measurement of biological processes at the molecular and cellular levels in humans and other living systems", has played an important role in cancer diagnosis. With the advances in nanotechnology, nanomaterials have emerged as a promising candidate for molecular imaging, due to their unique properties. Graphene is one of the most promising nanomaterials, which is intrinsically useful for drug loading and photo therapy of cancer. However, in vivo biodistribution and tumor targeting with graphene nanomaterial is an underexplored area. In this dissertation, we designed a radiolabeled antibody conjugated reduced graphene oxide (RGO) nanoplatform for in vivo positron emission tomography (PET) and tumor vasculature targeting. Excellent tumor uptake was achieved with 64Cu-NOTA-RGO-TRC105, compared to non-targeted RGO conjugate (64Cu-NOTA-RGO). Various experiments were performed, demonstrating that the vasculature targeting is highly specific (Chapter 2). In the following study, graphene oxide (GO), another subtype of graphene nanomaterials, was conjugated with anti-angiogenesis protein vascular endothelial growth factor 121 (VEGF121) to further validate the active targeting and imaging of graphene nanomaterials. Significantly enhanced tumor accumulation (>8 %ID/g) as well as high tumor-to-muscle contrast was achieved, showing great potential for future tumor targeted imaging (Chapter 3). Although traditional chelators are generally utilized in radiolabeling and PET imaging of nanomaterials, a novel chelator-free radiolabeling approach was designed with graphene nanoparticles (Chapter 4). The chelator-free radiolabeled RGO possesses decent labeling efficiency and enhanced in vivo radiostability over NOTA-chelated RGO, making it especially suitable for nanoparticle-based radiolabeling. Bypassing the use of chemical chelator, the intrinsically radiolabeled nanoparticles are able to maintain the native pharmacokinetics, and therefore more accurately reflect the distribution in vivo. Besides graphene, layered double hydroxide (LDH) and molybdenum disulfide (MoS2) nanoparticles were also employed for chelator-free radiolabeling and examined in vivo (Chapter 5 and 6). Excellent tumor uptake and in vivo integrity were observed, further validating the potential of chelator-free labeling in molecular imaging. Taking advantaging of molecular imaging and nanotechnology, a promising multifunctional nanoplatform can be designed for in vivo cancer management. Further efforts are necessary to thoroughly understand the in vivo behavior of nanoparticles and apply them in clinic
