Abstract
Since the discovery of ferromagnetic nanoparticles Fe3O4 that exhibit enzyme-like activity in 2007, the research on nanoenzymes has made significant progress. With the in-depth study of various nanoenzymes and the rapid development of related nanotechnology, nanoenzymes have emerged as a promising alternative to natural enzymes. Within nanozymes, there is a category of metal-based single-atom nanozymes that has been rapidly developed due to low cast, convenient preparation, long storage, less immunogenicity, and especially higher efficiency. More importantly, single-atom nanozymes possess the capacity to scavenge reactive oxygen species through various mechanisms, which is beneficial in the tissue repair process. Herein, this paper systemically highlights the types of metal single-atom nanozymes, their catalytic mechanisms, and their recent applications in tissue repair. The existing challenges are identified and the prospects of future research on nanozymes composed of metallic nanomaterials are proposed. We hope this review will illuminate the potential of single-atom nanozymes in tissue repair, encouraging their sequential clinical translation.

Abstract
The food additive E171 (titanium dioxide, TiO2), is widely used in foods, pharmaceuticals and cosmetics. It is a fine white powder, with at least one third of its particles sized in the nanoparticulate (˂100 nm range, TiO2 NPs). The use of E171 is controversial as its relevant risk assessment has never been satisfactorily accomplished. In vitro and in vivo studies have shown dose-dependent toxicity in various organs including the liver. TiO2 NPs have been shown to induce inflammation, cell death and structural and functional changes within the liver. The toxicity of TiO2 NPs in experimental models varies between organs and according to their physiochemical characteristics and parameters such as dosage and route of administration. Among these factors, ingestion is the most significant exposure route, and the liver is a key target organ. The aim of this review is to highlight the reported adverse effects of orally administered TiO2 NPs on the liver and to discuss the controversial state of its toxicity.

Abstract
The unique physicochemical properties inherent to nanoscale materials have unveiled numerous potential applications, spanning beyond the pharmaceutical and medical sectors into various consumer industries like food and cosmetics. Consequently, humans encounter nanomaterials through diverse exposure routes, giving rise to potential health considerations. Noteworthy among these materials are silica and specific metallic nanoparticles, extensively utilized in consumer products, which have garnered substantial attention due to their propensity to accumulate and induce adverse effects in the liver. This review paper aims to provide an exhaustive examination of the molecular mechanisms underpinning nanomaterial-induced hepatotoxicity, drawing insights from both in vitro and in vivo studies. Primarily, the most frequently observed manifestations of toxicity following the exposure of cells or animal models to various nanomaterials involve the initiation of oxidative stress and inflammation. Additionally, we delve into the existing in vitro models employed for evaluating the hepatotoxic effects of nanomaterials, emphasizing the persistent endeavors to advance and bolster the reliability of these models for nanotoxicology research.

The aqueous extract of Artemisia Absinthium L. stimulates HO-1/MT-1/Cyp450 signaling pathway via oxidative stress regulation induced by aluminium oxide nanoparticles (α and γ) animal model. BMC Complement Med Ther 2023; 23:310. [PMID: 37670294 PMCID: PMC10478434 DOI: 10.1186/s12906-023-04121-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Accepted: 08/08/2023] [Indexed: 09/07/2023] Open
Abstract
BACKGROUND This research aimed to evaluate the protective effects of Artemisia Absinthium L. (Abs) against liver damage induced by aluminium oxide nanoparticles (Al2O3 NPs) in rats, including both structural and functional changes associated with hepatotoxicity. METHODS Thirty-six rats were randomly divided into six groups (n = 6). The first group received no treatment. The second group was orally administered Abs at a dose of 200 mg/kg/b.w. The third and fifth groups were injected intraperitoneally with γ-Al2O3 NPs and α-Al2O3 NPs, respectively, at a dose of 30 mg/kg/b.w. The fourth and sixth groups were pre-treated with oral Abs at a dose of 200 mg/kg/b.w. along with intraperitoneal injection of γ-Al2O3 NPs and α-Al2O3 NPs, respectively, at a dose of 30 mg/kg/b.w. RESULTS Treatment with γ-Al2O3 NPs resulted in a significant decrease (P < 0.05) in total body weight gain, relative liver weight to body weight, and liver weight in rats. However, co-administration of γ-Al2O3 NPs with Abs significantly increased body weight gain (P < 0.05). Rats treated with Al2O3 NPs (γ and α) exhibited elevated levels of malondialdehyde (MDA), inducible nitric oxide synthase (iNOS), alanine transaminase (ALT), and aspartate aminotransferase (AST). Conversely, treatment significantly reduced glutathione peroxidase (GPx), catalase (CAT), total superoxide dismutase (T-SOD), and total antioxidant capacity (TAC) levels compared to the control group. Furthermore, the expression of heme oxygenase-1 (HO-1) and metallothionein-1 (MT-1) mRNAs, cytochrome P450 (CYP P450) protein, and histopathological changes were significantly up-regulated in rats injected with Al2O3 NPs. Pre-treatment with Abs significantly reduced MDA, AST, HO-1, and CYP P450 levels in the liver, while increasing GPx and T-SOD levels compared to rats treated with Al2O3 NPs. CONCLUSION The results indicate that Abs has potential protective effects against oxidative stress, up-regulation of oxidative-related genes and proteins, and histopathological alterations induced by Al2O3 NPs. Notably, γ-Al2O3 NPs exhibited greater hepatotoxicity than α-Al2O3 NPs.

Abstract
The widespread use of titanium dioxide nanoparticles (TiO2 NPs) in the food industry has brought about human safety risks related to nanotoxicity. In this study, food-related TiO2 NPs (anatase, 40 nm) were given to rats by oral gavage for 90 days at doses of 10, 100, and 1000 mg/kg bw. An additional two satellite groups underwent the same protocol for 45 days and for 90 days followed by a 28 day recovery. TiO2 NPs tended to agglomerate together in H2O, AGJ, and AIJ. No systemic toxicity was observed after 90 day agglomerated TiO2 NP exposure with no Ti distribution in major tissues/organs. Furthermore, TiO2 NP consumption for 90 days had no impact on microbiota diversity; the community structure of the gut microbiota is shifted to some extent at the genus level. Collectively, the NOAEL of agglomerated TiO2 NPs for 90 days of oral administration was 1000 mg/kg bw, the highest dose tested in male and female rats.

Abstract
Cu nanoparticles (CuNPs) have various applications in biomedicine, owing to their unique properties. As the effect of CuNPs on the induction of oxidative stress and apoptosis in the human colorectal cancer cell line SW480 has not yet been studied, we investigated the toxicity and mechanism of action of these NPs in SW480 cells. MTT assay was performed to assess the effect of the particles on the viability of SW480 cells. The levels of oxidative stress were assessed after 24 h of treatment with CuNPs by evaluating the Reactive Oxygen Specious (ROS) production. The antioxidant enzyme activity was assessed using a colorimetric method. To investigate the effect of NPs on cellular apoptosis, Hoechst33258 staining was performed, and the expression of Bax, Bcl-2, and p53 was evaluated by qRT-PCR. The MTT assay results showed that CuNPs inhibited the viability of SW480 cells. Moreover, the increase in ROS production at all three concentrations (31, 68, and 100 μg/ml) was significant. It has been observed that CuNPs lead to increased expression of Bax and p53, and decreased expression of Bcl-2. Hoechst staining was performed to confirm apoptosis. In conclusion, the induction of apoptosis demonstrated the anticancer potential of the CuNPs.

Abstract
Titanium dioxide nanoparticles (TiO2-NPs) are widely used, and humans are exposed through food (E171), cosmetics (e.g., toothpaste), and pharmaceuticals. The oral and gastrointestinal (GIT) tract are the first contact sites, but it may be systemically distributed. However, a robust adverse outcome pathway (AOP) has not been developed upon GIT exposure to TiO2-NPs. The aim of this review was to provide an integrative analysis of the published data on cellular and molecular mechanisms triggered after the ingestion of TiO2-NPs, proposing plausible AOPs that may drive policy decisions. A systematic review according to Prisma Methodology was performed in three databases of peer-reviewed literature: Pubmed, Scopus, and Web of Science. A total of 787 records were identified, screened in title/abstract, being 185 used for data extraction. The main endpoints identified were oxidative stress, cytotoxicity/apoptosis/cell death, inflammation, cellular and systemic uptake, genotoxicity, and carcinogenicity. From the results, AOPs were proposed where colorectal cancer, liver injury, reproductive toxicity, cardiac and kidney damage, as well as hematological effects stand out as possible adverse outcomes. The recent transgenerational studies also point to concerns with regard to population effects. Overall, the findings further support a limitation of the use of TiO2-NPs in food, announced by the European Food Safety Authority (EFSA).

ENVIRONMENTAL TOXICOLOGY AND PHARMACOLOGY 2022; 94:103931.

Abstract
The osmoregulation system of freshwater fish is sensitive to salinity increase in water. There is no satisfactory data to our knowledge on the accumulation of metal-oxide nanoparticles (NPs) in tissues of O. niloticus and their effects on ATPases (Na,K-ATPase, Mg-ATPase, Ca-ATPase) in differing salinities. Thus, this study investigated the effects of salinity (0 and 10 ppt) and Al2O3 and TiO2 NPs (1 and 10 mg NPs/L) on the response of ATPases in acute (2 days) and chronic (20 days) durations. Data showed that nanoparticles accumulated in the tissues of fish, gill tissues having the highest levels of Al and Ti in both acute and chronic durations. Interestingly, the higher salinity significantly increased (P < 0.05) NP accumulations in the tissues in acute exposures, whereas it significantly decreased (P < 0.05) in chronic exposures. Salinity increase caused significant decreases (P < 0.05) in ATPase activities (up to 54 %) in control fish from both exposure protocols. Likewise, NP alone exposures (up to 80 %) and salt+NP (up to 83 %) exposures generally caused significant (P < 0.05) decreases in ATPase activities compared to their controls. Similarly, salt+NP exposures also decreased ATPase activities compared to NP exposures alone. The present data demonstrated that salinity and/or NP exposures decreased ATPase activities in the gill of freshwater fish, emphasizing the possible hazardous consequences of salt inputs and NP discharges into freshwater systems.

The experimental animals (n = 72 mice) were divided into the following groups: group I, as a control; groups II and III, as aluminum oxide and its NPs (6 mg/kg); group IV, as aluminum oxide + nanocurcumin (Al2O3 + N-Cur, 20 mg/kg); and group V, as aluminum oxide NPs + nanocurcumin (Al2O3-NP + N.Cur., 20 mg/kg). Al2O3 and its NP groups significantly increased p53, Nrf2 levels, and the white blood cell count. They also decreased the Hsp70 level, antitrypsin, immunoglobulin G, and the red blood cell count. In addition, they significantly decreased the total and differential bone marrow cell counts and the maturation index ratio (MIR). Nanocurcumin (N.Cur.) reverted the previous proteins, blood parameters, total bone marrow cell count, and the MIR as M/E, I/Mg, MMI, I/Me, and EMI to normal. Furthermore, N.Cur. prevented apoptosis and reduced the histopathological score and collagen fiber percentage caused by Al2O3 and its NPs in the liver. Nanotechnology was used to increase the therapeutic efficiency of curcumin against the harmful effects of oxidative stress associated with Al2O3 NPs.

Assessment of Systemic Toxicity, Genotoxicity, and Early Phase Hepatocarcinogenicity of Iron (III)-Tannic Acid Nanoparticles in Rats. NANOMATERIALS (BASEL, SWITZERLAND) 2022; 12:1040. [PMID: 35407158 PMCID: PMC9000733 DOI: 10.3390/nano12071040] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/19/2022] [Revised: 03/09/2022] [Accepted: 03/19/2022] [Indexed: 02/07/2023]
Abstract
Iron-tannic acid nanoparticles (Fe-TA NPs) presented MRI contrast enhancement in both liver cancer cells and preneoplastic rat livers, while also exhibiting an anti-proliferative effect via enhanced autophagic death of liver cancer cells. Hence, a toxicity assessment of Fe-TA NPs was carried out in the present study. Acute and systemic toxicity of intraperitoneal Fe-TA NPs administration was investigated via a single dose of 55 mg/kg body weight (bw). Doses were then repeated 10 times within a range of 0.22 to 5.5 mg/kg bw every 3 days in rats. Furthermore, clastogenicity was assessed by rat liver micronucleus assay. Carcinogenicity was evaluated by medium-term carcinogenicity assay using glutathione S-transferase placental form positive foci as a preneoplastic marker, while three doses ranging from 0.55 to 17.5 mg/kg bw were administered 10 times weekly via intraperitoneum. Our study found that the LD50 value of Fe-TA NPs was greater than 55 mg/kg bw. Repeated dose administration of Fe-TA NPs over a period of 28 days and 10 weeks revealed no obvious signs of systemic toxicity, clastogenicity, and hepatocarcinogenicity. Furthermore, Fe-TA NPs did not alter liver function or serum iron status, however, increased liver iron content at certain dose in rats. Notably, antioxidant response was observed when a dose of 17.5 mg/kg bw was given to rats. Accordingly, our study found no signs of toxicity, genotoxicity, and early phase hepatocarcinogenicity of Fe-TA NPs in rats.

Abstract
Silver nanoparticles (AgNPs) have become increasingly popular in the biomedical field over the last few decades due to its proven antibacterial property. Previous scientific studies have reported that one of the major organs responsible for detoxification of AgNPs is the liver. The liver is also the primary organ responsible for secretion of angiotensinogen (AGT), a key signaling molecule involved in the renin-angiotensin system (RAS), which plays an important role in maintaining cardiac output and vascular pressure. The aim of this study was to assess any potential changes in the RAS-associated gene signaling, inflammatory response, and hepatocellular toxicity resulting from AgNP exposure. To do this, 6-week-old, male Wistar rats were exposed to a subacute inhalation exposure of AgNP (200 ppb/days over 4 h/days exposure, for 5 d) and their livers were analyzed for alterations in RAS components, inflammation, and oxidative stress. Real time qPCR analysis showed that AgNP-exposure resulted in a significant increase in hepatic AGT, angiotensin converting enzyme (ACE)-1, and ACE-2 mRNA expression. Expression of inflammatory markers interleukin (IL)-6, IL-1β, and tumor necrosis factor (TNF)-α were also upregulated with AgNP-exposure, compared to controls. Furthermore AgNP-exposure mediated a significant increase in hepatic expression of catalase, and superoxide dismutase, and oxidative stress, as assessed via 8-Oxo-2'-deoxyguanosine staining. Increased oxidative stress was associated with increased monocyte/macrophage-2 staining in the liver of AgNP-exposed rats. Such findings indicate that subacute inhalation exposure to AgNPs mediate increased hepatic RAS signaling, associated with inflammation, macrophage infiltration, and oxidative stress.

Abstract
Gold has always been regarded as a symbol of nobility, and its shiny golden appearance has always attracted the attention of many people. Gold has good ductility, molecular recognition properties, and good biocompatibility. At present, gold is being used in many fields. When gold particles are as small as several nanometers, their physical and chemical properties vary with their size in nanometers. The surface area of a nano-sized gold surface has a special effect. Therefore, gold nanoparticles can, directly and indirectly, give rise to different biological activities. For example, if the surface of the gold is sulfided. Various substances have a strong chemical reactivity and are easy to combine with sulfhydryl groups; hence, nanogold is often used in biomedical testing, disease diagnosis, and gene detection. Nanogold is easy to bind to proteins, such as antibodies, enzymes, or cytokines. In fact, scientists use nanogold to bind special antibodies, as a tool for targeting cancer cells. Gold nanoparticles are also directly cytotoxic to cancer cells. For diseases caused by inflammation and oxidative damage, gold nanoparticles also have antioxidant and anti-inflammatory effects. Based on these unique properties, gold nanoparticles have become the most widely studied metal nanomaterials. Many recent studies have further demonstrated that gold nanoparticles are beneficial for humans, due to their functional pharmacological properties in a variety of diseases. The content of this review will be the application of gold nanoparticles in treating or diagnosing pressing diseases, such as cancers, retinopathy, neurological diseases, skin disorders, bowel diseases, bone cartilage disorders, cardiovascular diseases, infections, and metabolic syndrome. Gold nanoparticles have shown very obvious therapeutic and application potential.

Abstract
Zinc oxide (ZnO) and copper oxide (CuO) nanoparticles (NPs) are widely used in medicine and industrial fields. They have negative effects such as hematoxic, cytotoxic, and genotoxic on animals. This research aimed to investigate the blood physiological and biochemical responses induced by ZnO-NP and CuO-NP individually or in combination in male Swiss albino mice. For purpose, NPs were given to mice with 100 μl of water by oral gavage for 14 days. Three sublethal NP dose groups (1, 5, 25 mg/kg/day) and one control group (only received 100 μl of water) were used in the experiments and serum metabolite (glucose, total protein, total cholesterol, triglyceride, cortisol, blood urea nitrogen, immunoglobulin G, and M), ions (Na, K, Cl, Mg, and Ca), and enzyme (ALT, AST, ALP, and LDH) levels were measured. ZnO-, CuO-, and ZnO+CuO-NPs especially higher doses (5 and 25 mg/kg/day) decreased all serum metabolite (except blood urea nitrogen), ions, and ALP while these nanoparticles increased ALT, AST, LDH, and blood urea nitrogen. These increases/decreases in all serum parameters were generally higher in mice treated with the ZnO+CuO-NP mixture compared to the ZnO-NP and CuO-NP groups alone. The study shows that serum biochemistry profiles can be used as indicators to assess nanoparticle toxicity on lipid, protein, and energy metabolisms, immune and enzyme systems, ion regulation, and tissue functions.

Abstract
This study describes the adsorption of free radical TEMPO onto Al2O3 nanoparticles in the solvents with different polarities including DMF, methanol, acetone, THF, petroleum ether and n-hexane at ambient temperature to evaluate the radical scavenging activity. The adsorption percentage of radical is calculated by measuring the maximum adsorption intensity of the ultraviolet (UV) absorption spectrum of TEMPO in the presence and the absence of Al2O3 nanoparticles. The morphology of Al2O3 nanoparticles before and after adsorption of TEMPO is studied using transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier-transform infrared (FT-IR) spectroscopy. The adsorption energy and other thermochemical data for the adsorption of TEMPO over different active sites of Al2O3 are estimated via dispersion corrected density functional theory (DFT + Disp). The donor-acceptor interactions between Al2O3 and TEMPO are calculated using natural bond orbital (NBO) theory. It is found that Al2O3 nanoparticles have efficient radical scavenging activity (RSA) in the range of 50-72%. Approximately, a linear relationship between dielectric constant of solvent and the absorption percentage of TEMPO over Al2O3 nanoparticles is achieved. So that with decreasing the polarity of solvent, the adsorption of TEMPO onto Al2O3 nanoparticles is increased. The adsorption of TEMPO over Lewis acidic sites of Al2O3 is more favored than Brønsted acidic and basic sites. The comparison between experimental and calculated IR spectra of TEMPO/Al2O3 complexes provides the good evidence for adsorption of TEMPO onto the surface of Al2O3 nanoparticles.

Abstract
PURPOSE Mussels are known as the natural filters of the aquatic systems and are accepted as one of the best bioindicator organism. There is no data on the response of Unio tigridis to metal-oxide nanoparticle (NP) exposures. This study aimed to investigate the response of the antioxidant enzymes of U. tigridis following exposure to NPs. MATERIALS AND METHODS The mussels were exposed to different concentrations (0, 1, 3, 9 mg NP/L) of Al2O3, CuO and TiO2 NPs for 14 days and subsequently, the activities of CAT (catalase), SOD (superoxide dismutase), GPx (glutathione peroxidase), GST (glutathione S-transferase) and GR (glutathione reductase) were measured in the gill and digestive gland. Mussels were fed with cultured unicellular algae (Chlorella vulgaris) during experiments. RESULTS Data showed that algae consumptions of mussels were not significantly (p>0.05) altered by NPs. However, all enzyme activities in the digestive gland and gill altered significantly (p<0.05) after NP exposures. The activities of CAT and SOD decreased, while the activities of enzymes belonging to glutathione metabolism (GPx and GST) increased in both tissues. CONCLUSION This study representing the first record on the antioxidant system response of U. tigridis toward NP exposures suggests that NP toxicity should be investigated thoroughly in organisms and some regulations must be done on their usages.

Abstract
The fast-growing applications of engineered titanium dioxide nanoparticles (e-TiO2-NPs) in the food and pharmaceutical industry in production, packaging, sensors, nutrient delivery systems, and food additives enhance the possibility of oral exposure. Physicochemical transformations may occur when e-TiO2-NPs are incorporated into a food matrix and pass through the human gastrointestinal tract (GIT), which may redefine the toxic effects of the e-TiO2-NPs. In this study, a standardized food model (SFM) and simulated gastrointestinal fluids have been used to study the fate of e-TiO2-NPs following a three-step digestion model in vitro, and a case study was carried out to assess the toxicity of the digested e-TiO2-NPs using an in vitro cellular model. In the absence and presence of the SFM, the transformations of the tristimulus color coordinates, size, agglomeration state, surface charge and solubility of the e-TiO2-NPs in the salivary, gastric and intestinal digestion fluids were compared with those before digestion. The results demonstrate that the presence of the SFM impacted the physicochemical properties of the e-TiO2-NPs significantly. The SFM stabilized the e-TiO2-NP suspensions and acted as a dispersant during each digestive phase. The e-TiO2-NPs showed differentiated transformations of their physicochemical properties after each step of the digestive process. The pH shifts and variable concentrations of enzymes and salts in gastrointestinal fluids induced the transformations of the physicochemical properties of the e-TiO2-NPs. The transformed e-TiO2-NPs could release titanium ion in the gastrointestinal tract. Also, the cell viability induced by e-TiO2-NPs was found to be strongly affected by the presence of the SFM and simulated human GIT fluids. It can be concluded that the physicochemical transformations of the e-TiO2-NPs that were found when they were incorporated into an SFM and passed through the GIT consequently strongly affected the biological effects of the e-TiO2-NPs, which highlights that the toxicity assessment of ingested NPs should use appropriate standardized food models and take realistic physiological conditions into account.

Abstract
PURPOSE Accumulation of Gamma aluminium oxide nanoparticles γ-Al2O3 NPs significant impact on aquatic ecosystems. However, the toxicity of γ-Al2O3 NPs in aquatic organisms has been limited investigated. This study investigated histopathological changes and antioxidant responses induced by different concentrations of γ-Al2O3 NPs in Mytilus galloprovincialis. MATERIAL AND METHODS In this study, mussels were exposed to different concentrations of 5 nm γ-Al2O3 NPs (0, 5, 20 and 40 mg/L) for 96 h under controlled laboratory conditions. Gill and digestive gland from mussels were assessed to histopathological (light microscopy, histopathological condition indices, digestive gland tubule types), SOD, CAT, GPx activities. RESULTS Histopathological indices calculated higher, and significantly different in all exposure groups compared to the control group in gill and digestive gland (p < 0.05). Atrophic phase tubules proportion very high in 20 and 40 mg/L γ-Al2O3 NPs exposure groups. No significant changes in CAT activities in the gill and digestive gland (p > 0.05). Superoxide dismutase (SOD) activities significantly different (p ≤ 0.05) in the digestive gland from 20 mg/L γ-Al2O3 NPs exposures, and GPx activities significantly different (p < 0.05) in gill from 40 mg/L γ-Al2O3 NPs exposures. CONCLUSION These results indicate that contamination of γ-Al2O3 NPs negatively affects the aquatic organism.

Abstract
Titanium dioxide (TiO2) nanoparticles (NPs) are widely used in industry, pharmacy, medicine, and food sectors. Therefore, this study deals with the effects of TiO2 NPs in female rats following oral administration in differing doses for 14 days (0, 0.5, 5, and 50 mg/kg b.w./d). The response of enzymatic biomarkers (Na,K-ATPase, Mg-ATPase, and AChE) was measured in the brain, kidney, and small intestine, while non-enzymatic biomarker levels, such as different forms of glutathione (GSH) and thiobarbituric acid reactive substances (TBARSs) were measured in the liver. The images of the tissues were obtained using a transmission electron microscope (TEM) to demonstrate TiO2 NP accumulation. Data showed that brain AChE activity decreased at all TiO2 NP doses, though brain ATPase activities increased. However, ATPase activities in the intestine and kidney did not change significantly. Levels of GSH forms did not change significantly, though there was a significant decrease in TBARS level at the highest NP dose. TEM images demonstrated that TiO2 NPs accumulated in a dose-dependent manner in the tissues. Data emphasized that the brain was the most sensitive organ against the effects of TiO2 NPs. This study suggests the need for further studies to evaluate better the toxic effects of TiO2 NPs.

Abstract
Use of biomaterial scaffolds as drug carriers for infected wounds treatment is of wide scope. A series of curcumin/TiO2 complex loaded chitosan scaffolds are fabricated for the same. Synthesized wound dressing material is screened for their morphology, water absorption capacity; in vitro drug release patterns, in vitro antibacterial studies against gram +ve and a gram -ve bacteria, cell viability for 3T3-L1 cell lines as well as in vivo MRSA infected wound healing capability. Formation of curcumin/TiO2 complex was confirmed by X-ray diffraction studies, the anchoring pattern of them on the chitosan scaffold was analyzed by FESEM and EDS mapping. All membranes showed a better performance towards in vitro antibacterial and in vivo wound healing properties than the control ones in 14 days. The bacterial count on wound for a regular time period was measured and the scaffold with higher amount of curcumin in its complex is found to give the better performance, along with skin regeneration due to synergistic effect of curcumin and TiO2.
