Normally, given the complexity of nanoparticles administration routes and undesirable interactions with non-specific molecules within the organisms, the difference in the nanoparticles affinity towards cancerous and normal cells would not be sufficient for high specificity and efficient delivery to the target site required for wide utility for biomedical applications. 5 [103]. The results designated that long rods are more easily internalized by A375 human melanoma cells, when compared to short rods and spheres shapes [108]. Another key issue is the challenge of regulatory approval of nanomedicines, as there are no specific guidelines set by FDA for the products with nanomaterials.

An understanding of nano-bio interfacial interactions and targeting of nanoparticles to the tumor cells is essential for cancer therapy and management. 65, 393404 (2018), H.K. However, more in-depth studies are required to understand the pharmacokinetic and pharmacodynamic properties of these systems before clinical translation of mesoporous silica-based nanomaterials. This is known as enhanced permeability and retention (EPR) effect, which is the basis of passive targeting [31]. Accessibility Pharm. There are several studies reporting on successful applications of passive targeting of tumor cells and a successful translation into clinical therapeutics. 9(2), 194201 (2013), P.M. Valencia et al., Effects of ligands with different water solubilities on self-assembly and properties of targeted nanoparticles. Biotechnol. The cytotoxicity of the dendrimer encapsulated doxorubicin and LFC131-DOX-D4 to BT-549-Luc cells was evaluated and the IC50 value of LFC131-DOXD4 was 2.8 fold of DOX-D4 against BT-549-Luc cells and it was 6.8 fold of DOX-D4 against T47D cells after 24h of incubation, indicating that the ligand conjugated doxorubicin encapsulated dendrimer can enhance the cytotoxicity of the drug against the cancer cell lines [281]. Recently, Wan et al. Nanotechnology enabling the use of circulating tumor cells (CTCs) as reliable cancer biomarkers. Chem. Sci. 10(9), 32233230 (2010), P.N. 509(1), 168177 (2016), A. Kumari, S.K. 10, 51235137 (2015), Z.C. Therefore, in this critical review, we summarize a range of nanomaterials which are currently being employed for anticancer therapies and discuss the fundamental role of their physicochemical properties in cancer management. Uptake was less effective with the negatively charged particles, however, indicating the role of negative surface charge on the nanoparticles, which can reduce the undesirable clearance by liver cells [111]. Active targeting approach has been exploited to increase internalization of nanoparticles by the target cells and improve the drug delivery efficacy. The cytotoxicity of doxorubicin-loaded mesoporous silica nanomaterials toward cancer cells overexpressing CD44 receptor was enhanced with IC50 of 0.56g/mL whereas; the normal cells showed lower cytotoxicity with the IC50of 1.03g/mL [225]. Soc. From the above discussion, it is evident that dendrimers are nanoplatforms which can be tuned for therapeutic applications, and show great promise in the treatment of various cancers. Effect of OVA-iron oxide nanoparticles: macrophages activation with different concentrations of OVA, and production of a TNF-, b IL-6, c IFN-. Funct. However, in some tumor cases the size of nanoparticles should be tuned according to the vasculature lining gap size [59]. Likewise, Huang et al. There is a multitude of other factors that can present potential challenges for nanotherapeutics such as low blood circulation rate in tumor vessels, tumor site macrophages, and extracellular matrices environment around tumor cells. Photobiol. Nguyen et al., Redox-sensitive nanoparticles from amphiphilic cholesterol-based block copolymers for enhanced tumor intracellular release of doxorubicin.

As an example, drug-coated nanoparticles completely inhibited lung tumor in mice, leading to enhanced survival rate and reduced adverse effect when compared to the free drug [123]. These nanocarriers help overcome the unwanted side effects in normal tissues and increase circulation time, bioavailability, and accumulation of drug at target-site by reducing toxicity and protect the chemotherapeutic agents from the surrounding environment. Pharm. Res. Similarly, the PEGylated liposomes have been used in delivering celastrol, irinotecan, resveratrol in the treatment of breast cancer and glioblastoma [236, 237]. Nanoconstructs for theranostic application in cancer: Challenges and strategies to enhance the delivery. Commun. Drug Deliv. 12(8), 28112822 (2015), I.M. Specifically, the use of nanocarriers for drug delivery offers many advantages; (i) circumvent the problems of solubility and stability of anticancer drugs; (ii) prevents the drug from degradation from proteases and other enzymes and increase the half-life of the drug in the systemic circulation; (iii) improves drug distribution and targeting; (iv) helps in the sustained release of drug by targeting the cancer sites and (v) helps in delivery of multiple drugs and, therefore helps inreducing drug resistance [23].

Bhattacharyya et al. Rev. Eur. The pH responsive release of the drug is widely employed, since the tumor microenvironment will be slightly more acidic than the normal tissues. The ex vivo permeability of these formulations tested on mice dorsal skin and in vivo anticancer activity were evaluated in A431 tumor-bearing mice. The heat generated due to Neel and Brownian relaxation as well as hysteresis loss can be used to kill tumor cells in the vicinity of IONPs [49].
