Previous studies have indicated that ROS and autophagy are involved in the cytotoxicity of ZnO NPs, but the regulatory mechanisms between autophagy and ROS remain to be elucidated. Biosynthetic and environment friendly technology for the synthesis of ZnO NPs are believed to be more ecofriendly, economical (low priced), nontoxic, and biocompatible than chemical and physical methods. ZnO NPs have acquired tremendous interest in cancer drug delivery. Encouraging, HA/ZnO nanocomposite treatment for 72 hours did not cause toxicity to the normal human lung fibroblast (MRC-5) cell line. Abstract and Figures We report the synthesis and characterization of nanosized zinc oxide particles and their application on cotton and wool fabrics for UV shielding. The emission color can be changed via adjusting the pH of the precipitation solutions. By targeting the specific sites of cancer cells, nanoparticle-based drug delivery could reduce the overall amount of drugs used and thus minimize undesirable side effects [9, 66].

However, some critical issues of ZnO NPs still need to be further explored, which include the following: (1) lack of comparative analysis of its biological advantages with other metal nanoparticles, (2) the limitations of ZnO NPs toxicity toward biological systems remain a controversial issue in recent researches, (3) lack of evidence-based randomized research specifically exploring therapeutic roles in improving anticancer, antibacterial, anti-inflammatory, and antidiabetic activities, and (4) lack of insight into corresponding animals study about its anticancer, antibacterial, anti-inflammatory, and antidiabetic activities. ZnO NPs can be selected as an antibacterial material because of its superior properties, such as high specific surface area and high activity to block a wide scope of pathogenic agents. Based on its advanced intrinsic fluorescence, ZnO nanomaterial can also be used as a promising candidate for cell imaging and pathological studies. Arakha et al. The ZnO NPs-induced apoptosis was mainly through both extrinsic and intrinsic apoptotic pathways, and some antiapoptotic genes of Bcl-2, AKT1, and JERK/2 were downregulated, while proapoptotic genes of p21, p53, JNK, and Bax were upregulated.

The hyperglycemia can directly enhance an inflammatory state by regulating C-reactive protein (CRP) and cytokines, such as interleukins, which is involved in the development of cardiovascular diseases. ZnO NPs exhibit efficient blue emissions and near-UV emissions, which have green or yellow luminescence related to oxygen vacancies, therefore further extending its application into bioimaging field [12, 36, 120]. The contribution of zinc oxide (ZnO) nanoparticles currently used in … found that ZnO NPs with a crystal size of 20 nm resulted in a concentration-dependent loss of ovarian cancer SKOV3 cell viability [51]. Sanni Kapatel, C. K. Sumesh. Pardeshi and Patil synthesized ZnO NPs with different morphologies and crystallite sizes using this method by varying the calcination temperature from 400°C to 900°C. It exhibited emission colors of blue, green, yellow, and orange [123]. Recently, nanomaterial-based nanomedicine, with high biocompatibility, easily surface functionalization, cancer targeting, and drug delivery capacity, has demonstrated the potential to overcome these side effects. But the morphology of the ZnO NPs strongly depends on the milling time of the reactant mixture, a longer time of milling led to a smaller particle size. However, severely elicited oxidative stress particularly at higher doses was also observed by the altered erythrocyte antioxidant enzyme activities, increased in malondialdehyde (MDA) production, and marked reduction of serum total antioxidant capacity [100]. It found that ZnO NPs with small dimensions at higher doses (3 and 10 mg/kg) had a much greater antidiabetic effect compared to ZnSO4 (30 mg/kg). extracted crustacean immune molecule β-1,3-glucan binding protein (Phβ-GBP) from the heamolymph of Paratelphusa hydrodromus and then successfully fabricated the Phβ-GBP-coated ZnO NPs. These results would damage bacterial membrane, increase permeabilization, and substantially modify their morphology [85]. In general, the anticancer activity of nanoscaled ZnO materials with prominent functionality may provide a new opportunity for exploiting ZnO NPs in treating cancer diseases. ZnO NPs present certain cytotoxicity in cancer cells mainly by themselves based on a higher intracellular release of dissolved zinc ions, followed by increased ROS induction and induced cancer cell death via the apoptosis signaling pathway. Wiegand explored the role of ZnO-functionalized textile fibers in the control of oxidative stress in AD in vitro and in vivo [114]. Chem. ZnO NPs are listed as a kind of safe substance by the FDA. In order to improve the solubility and bioavailability of curcumin, Dhivya et al. As far as method of formation is concerned, ZnO NPs can be synthesized by several chemical methods such as precipitation method, vapor transport method, and hydrothermal process. Journal of Drug Delivery Science and Technology, https://doi.org/10.1016/j.jddst.2020.101911. Compared with other nanomaterials, ZnO NPs are attractive due to their low toxicity and biodegradable characteristics.

Different types of drugs such as doxorubicin, paclitaxel, curcumin, and baicalin or DNA fragments could be loaded onto the ZnO NPs to show better solubility, higher toxicity compared with individual agents, and effective delivery into cancer cells [48, 67–69]. Using a simple sol-gel method, Xiong et al. Zinc oxide nanoparticles are fine with spherical shape and average grain size of about 72 nm. Bai et al. Gram‐positive bacteria were generally more sensitive to ZnO than Gram negatives. In the past two decades, ZnO NPs have become one of the most popular metal oxide nanoparticles in biological applications due to their excellent biocompatibility, economic, and low toxicity. INTRODUCTION Zinc oxide is frequently used in several areas of … Research paper on zinc oxide nanoparticles for thesis search british library. We are committed to sharing findings related to COVID-19 as quickly as possible. The addition of radical scavengers such as mannitol, vitamin E, and glutathione could block the bactericidal action of ZnO NPs, potentially revealing that ROS production played a necessary function in the antibacterial properties of ZnO NPs. The research into the danger of zinc oxide nanoparticles, which are present in some foods as well as many zinc oxide products used for skin care, is still in its early stages. View Zinc oxide Nanoparticles Research Papers on Academia.edu for free. The mechanism of ZnO NPs-induced toxicity in human liver cells [. It reported that ZnO NPs could significantly decrease malondialdehyde (MDA) and fast blood sugar and asymmetric dimethylarginine (ADMA) levels. Compared with bZnO, nZnO exerted higher anti-inflammatory properties by decreasing drastically on proinflammatory cytokines (IL-10, IL-13, IFN-γ, and Th2 cytokines) in the mouse model of AD. The advent of nanotechnology has led the development of materials with new properties for use as antimicrobial agents. The ZnO@polymer core-shell nanoparticles exhibited high quantum yield and very stable broad photoluminescence in aqueous solutions. This study was designed to develop green synthesized zinc oxide nanoparticles (ZnO-NPs) as potential nano-antibiotics against drug resistant microbes along with multifarious biomedical applications. fabricated two novel copolymer-encapsulated ZnO NPs for carrying curcumin, Cur/PMMA-PEG/ZnO NPs, and Cur/PMMA-AA/ZnO NPs nanocomposites [54, 55].
