Pharm. official website and that any information you provide is encrypted Interestingly, in contrast to the more-ligand-more-targeting notion, there have been a few observations wherein increasing ligand density to increase total affinity did not always have a linear relationship with ligand density. To ascertain this dependence, three different sizes and two different shapes (13nm sphere, 50nm sphere and 40nm star) of siRNA-conjugated gold nanoconstructs were developed to check the in vitro response of U87 glioblastoma cells targeting the expression of isocitrate dehydrogenase 1.

These accumulated nanoparticles were captured and quickly cleared by macrophages resulting in suboptimal tumor cell internalization [47]. Disadvantages Nanotechnology offers many potential advantages, however, there are also potential disadvantages of nanotechnology, including: Health risks: There is some concern that exposure to nanoparticles could be harmful to human health, as they can easily penetrate cells and tissues.

Introduction. A wide range of materials have been used to develop nanocarriers. Biotechnol. Pharm. Hence nanotechnology has a deep impact on the environment. Active targeting approach has been exploited to increase internalization of nanoparticles by the target cells and improve the drug delivery efficacy. Dalton Trans. Target substrates can be surface molecules expressed in diseased cells, proteins, sugars or lipids present in the organs, molecules present (or secreted by tumor cells) in the microenvironment of the diseased cells or even the physicochemical environment in the vicinity [46]. In open-loop control systems, external factors such as magnetic pulses, thermal, acoustic pulses or electric fields control drug release. Nanoparticles (1-100 nm) can be used to treat cancer due to their specific advantages such as biocompatibility, reduced toxicity, more excellent stability, enhanced permeability and retention effect, and precise targeting. Table2 highlights various inorganic nanocarriers for delivery of anticancer therapeutics. Mater. Also, binding of one ligand molecule generally facilitates binding of consequent molecules through cooperativity effects, collectively enhancing the binding efficiency and subsequent actions. Cancer Cell Int. Sci. Acta 1806(1), 2935 (2010), J.T. 2(2), 85120 (2009), A. Accardo, G. Morelli, Review peptide-targeted liposomes for selective drug delivery: advantages and problematic issues. Ligand density on the nanoparticles dictates the strength of avidity towards the substrate, so approaches used to conjugate ligands on the surface of nanoparticles are critical aspects of the targeted systems. In conjunction to physicochemical properties, the nanomaterial storage and stability may also have an influence on their pharmacological performance [287, 288]. However, the detection of cancer in the early stage has been hindered by the intrinsic limits of conventional cancer diagnostic methods. Similarly, pH sensitive liposomes have also proved to be effective in increasing the drug accumulation in resistant tumor cells and are potent drug carriers that can overcome multidrug resistance.

Another polymeric nanoparticle platform that is gaining significant attention as drug delivery systems is polymer micelle nanoparticles. In addition, many other factors have a profound consequence on nanomaterials uptake and distribution in cells. 9, 789 (2003), P.N. Polymeric nanoparticles are colloidal nanoparticles wherein therapeutic molecules will be encapsulated or adsorbed or conjugated in the polymer matrix. Similar to Au nanoparticles,silver (Ag) nanoparticles havealso been demonstrated to be used as anticancer agents for the treatment of multiple types of cancer [144,145,146,147]. Liu et al.

In the study, three different targeted nanoparticles and one non-targeted nanoparticle were used to study the uptake and distribution of iron oxide nanoparticles in the PANC02 mouse pancreatic cancer cell line. However, some cons have also been noticed due to which the use of nanotechnology at a larger scale is not being encouraged. 132(13), 46784684 (2010), I. In general, positively charged nanomaterials may internalize efficiently at cell membranes, because of the negative charge on the cell surface [113]. Additionally, the in vivo biodistribution of nanoparticles suggest that the negatively charged particles accumulate in tumor sites more efficiently [110].
