Nanoparticles as drug delivery systems enable unique approaches for cancer treatment. Over the last two decades, a large number of nanoparticle delivery systems have been developed for cancer therapy, including organic and inorganic materials. Many liposomal, polymer-drug conjugates, and micellar formulations are part of the state of the art in the clinics, and an even greater number of nanoparticle platforms are currently in the preclinical stages of development. More recently developed nanoparticles are demonstrating the potential sophistication of these delivery systems by incorporating multifunctional capabilities and targeting strategies in an effort to increase the efficacy of these systems against the most difficult cancer challenges, including drug resistance and metastatic disease. In this chapter, we will review the available preclinical and clinical nanoparticle technology platforms and their impact for cancer therapy.

Recent advances in nanomedicine , a multidisciplinary field that involves the application of nanomaterials in medicine and healthcare, offer a promising alternative for cancer treatment (Farrell et al. 2010; Alexis et al. 2010; Sahoo et al. 2007). Due to their small size and the fact that they can be easily modified, nanomaterials demonstrate significant advantages in gaining access to cancer cells, by either passive or active targeting. "

    ABSTRACT: Breast cancer is the leading cause of cancer deaths in women. Recent advances in nanomedicine have shown that gold nanorods (AuNRs), as multifunctional drug delivery and photothermal therapeutic agents, have potential for use in cancer therapy. However, the effect of AuNRs on the transcriptome of breast cancer cells is unknown. In the present study, cells of the triple-negative human breast cancer cell line MDA-MB-231, which has high metastatic activity, were treated with AuNRs for transcriptomic analysis using RNA-seq technology. In total, 3126 genes were found to be up-regulated and 3558 genes were found to be down-regulated in AuNR-treated MDA-MB-231 cells. These differentially expressed genes presumably take part in multiple biological pathways, including glycolysis and regulation of the actin cytoskeleton, and impact a variety of cellular functions, including chemoattractant activity. The distinct gene expression profile of MDA-MB-231 cells treated with AuNRs provides a foundation for further screening and validation of important genes involved in the interaction between AuNRs and MDA-MB-231 cells.

    ABSTRACT: Lyophilisomes are a novel class of proteinaceous biodegradable nano/microparticle capsules developed for tumor drug delivery. The in vivo characteristics of lyophilisomes are unknown and, therefore, the time course of biodistribution of sized albumin-based lyophilisomes in CD1 mice after intravenous administration was studied. Lyophilisomes, prepared from Dylight680-labeled albumin, were sized using a sucrose gradient centrifugation methodology and four fractions with a mean size of approximately 200 nm, 400 nm, 550 nm, and 650 nm were pooled for in/ex vivo localization, (immuno)histochemistry and biochemical analysis. Lyophilisomes were rapidly taken out of the circulation by the liver and spleen. Immunohistochemistry revealed that lyophilisomes were taken up in the liver by F4/80 positive macrophages, and in the spleen by Sign-R1 positive macrophages specifically located in the marginal zones. Lyophilisomes were most likely degraded by the liver and spleen and subsequently excreted via the urine, as high levels of degraded Dylight680-labeled albumin were detected in the urine. This was corroborated by electron microscopy of the spleen, which showed intact lyophilisomes in the marginal zone 5 and 30 min after injection, but not after 2 h. In conclusion, i.v. injected lyophilisomes are rapidly entrapped by liver and splenic macrophages, biodegraded, and excreted in the urine. Copyright © 2015. Published by Elsevier B.V.

These NPs have attracted great interest due to the wide variety of its applications [3]. Its small size allows them to cross biological barriers, join or internalize into cells and distribute throughout the body through the blood stream [4]. "

    ABSTRACT: Photo-thermal therapies, based on the light-induced local heating of cancer tumors and tissues, are nowadays attracting an increasing attention due to their effectiveness, universality, and low cost. In order to avoid undesirable collateral damage in the healthy tissues surrounding the tumors, photo-thermal therapies should be achieved while monitoring tumor’s temperature in such a way that thermal therapy could be stopped before reaching the damage limit. Measuring tumor temperature is not an easy task at all and novel strategies should be adopted. In this work it is demonstrated how luminescent nanoparticles, in particular Neodymium doped LaF3 nanoparticles, could be used as multi-functional agents capable of simultaneous heating and thermal sensing. Advantages and disadvantages of such nanoparticles are discussed and the future perspectives are briefly raised.
