Several researchers have demonstrated that half-generation dendrimers exhibit lower toxicity than the full generation of polyamide amine [277,278,279]. Thus, the nanomaterials used for targeting tumor cells should have the capability of increasing local concentration of the drugs in and around tumor cells, thereby reducing the potential toxicity toward healthy cells [27]. Keywords: The regulatory verdicts on the nanoformulated drugs are based on the individual assessment of paybacks and perils, making evaluations a time-consuming affair that causes delays in commercialization. Int. Recently, a theranostic nanoparticle to enhance intra-tumoral drug delivery by overcoming drug resistance and providing image-guided drug delivery by reducing the systemic toxicity was developed using iron oxide nanoparticles. The nanocarriers need to be smaller than the cut-off of the proportions in the neovasculature, with the extravasation to the tumor acutely affected by the size of the vehicle. Further, they measured the localization and internalization of these nanoparticles using magnetic resonance imaging (MRI) exploiting IONPs properties as contrast agents. 5 [103]. Chem. Chem.

All these strategies can reduce the systemic toxicity at the tumor sites by ensuring that healthy cells are not affected. Mol. Cell Cycle 8(22), 36153616 (2009), P.N. These features have led many researchers to load cargos on to mesoporous silica nanomaterials for transporting them to the tumor tissues [218,219,220]. These studies do raise concerns about how an appropriate optimization of targeting moieties, conjugation approaches and densities play an essential role in the desired outcomes of the therapeutic nanosystems. 28(11), 28152822 (2017), V. Karthika et al., Biocompatible properties of nano-drug carriers using TiO2Au embedded on multiwall carbon nanotubes for targeted drug delivery. Despite efforts to mitigate risk factors in recent decades, the prevalence of cancer is continuing to increase [1]. Additionally, since these nanocarriers interact with the biomolecules and may tend to aggregate forming a protein corona, disturbing the regular function of nanomedicine formulations and rendering them ineffective in controlling the cancer cell growth [286]. Sci. However, their use is often limited due to the accumulation of metal in the body after drug administration causing toxicity. Pept. Macromol.
