“…Along with this the size, shape, structure and composition of nanomaterials also plays a crucial role in the antibacterial activity [45]. The nano-biointerface is an important phenomenon for the understanding of antibacterial activity [23][24][25][26]. The interface between a nanoparticle and any living moiety or biomaterial is termed as nanobiointerface.…”

“…The cell death may occur due to excess level of oxygen species after exposure to nanomaterials following the oxidative stress mechanism. However, the antibacterial activity of MoO 3 is related to the release of hydroxinium ion according to the following reaction [26]. Initially the molybdenum trioxide reacts with the water to form molybdic acid.…”

“…Hence in the recent years there is growing demand for metal oxide nanoparticles as antibacterial agent due to their high stability and non toxic nature [23][24][25]. Recently Zollfrank et al reported that antimicrobial activity of transition metal acid MoO 3 is related to their surface acidity involving the intermediate formation of molybdic acid [26]. The toxicity of MoO 3 towards pathogenic bacteria has been studied by K. Krishnamoorthy et al [27].…”

In the present investigation, sea urchin like morphology of h-MoO 3 nanorods are successfully synthesized by chemical bath deposition (CBD) technique. The thermal stability, structural details, morphology and compositional analysis of MoO 3 was done using thermogravimetry (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), high resolution transmission electron microscopy (HR-TEM), selected area electron diffraction (SAED) and X-ray photoelectron spectroscopy (XPS) techniques respectively. The thermal analysis reveals presence of sharp exothermic peak at 409ºC indicating irreversible phase transition. X-ray diffraction pattern showed hexagonal to orthorhombic phase transition after annealing at 450ºC. As synthesized h-MoO 3 shows well oriented hexagonal rods with sea urchin like architecture while that of annealed MoO 3 sample revealed 2D layer by layer growth. The SAED pattern confirms single crystalline nature of as synthesized h-MoO 3 and polycrystalline nature of annealed α-MoO 3 . While XPS study of both confirms Mo +6 and O 2-oxidation states of elements. Furthermore, characteristic antibacterial properties of h-MoO 3 and α-MoO 3 against gram positive Bacillus megaterium, Streptococcus aureus and gram negative Escherichia coli is noted.

“…Further efforts are required to improve the traditional methods in decontamination of toilet surfaces. New methodologies and techniques are needed with "permanent" antimicrobial effect without risk of generating micro-organisms resistance [6] [7]. Titanium dioxide (TiO 2 ) is non-toxic, available, cost effective, chemically stable and with favorable properties [8].…”

The infection control in surfaces of public toilets environment is a matter of great concern and a major challenge, especially during mass gatherings. The present study aimed to evaluate the antimicrobial efficacy of titanium dioxide nanoparticles coating on environmental surfaces of public toilets during Hajj time. A pilot study has been designed to evaluate the antimicrobial efficacy of titanium dioxide nanoparticles on the surfaces of public toilets. The results showed a significant reduction in colony-count of the test samples. Maximum average reduction count of test microbes of the seats and walls reached (99.7%) while that of the doors reached (99.1%) which was statistically significant (P value = 0.001). It was concluded that there was a marked effect of a mixed TiO2 coating on reducing the microbial count at the surfaces of public toilets environments. Further research on efficacy against specific organisms, intestinal parasites, fungi, viruses and bacteriophage is recommended.

“…Nanoparticles (NPs) are frequently found commercially as cosmetics and sunscreens (TiO 2 , Fe 3 O 4 , and ZnO), fillers in dental fillings (SiO 2 ), in water filtration and catalytic systems, and in photovoltaic cells (CdS, CdSe, ZnS). Molybdenum trioxide (MoO 3 ) nanoparticles are widely used as a catalyst, cracking catalyst, hydrogenation catalyst, pigment, and in ceramics and glass production (Zollfrank et al, 2012). Because of its layered structure and the ease of the Mo (VI)/ Mo (V) coupling, MoO 3 is of interest in electrochemical devices and displays.…”

SUMMARY: Special features of nanoparticles have resulted in their widespread use. Small molybdenum trioxide (MoO 3 ) nanoparticles can translocate from the entry portals into the circulatory and lymphatic systems and ultimately to body tissues and organs depending on their composition and size. In this research, sixty Wistar rats weighting 180-250 g were divided into 6 groups (n=10) randomly: Group 1 (Control) did not receive any medicine. Group 2 (Sham) received intraperitoneal normal saline for 35 days on a daily basis. Groups 3, 4, 5 and 6 received 50, 100, 200, and 300 mg/kg MoO 3 , respectively, the same way in the sham group and at the same interval. At the end of the experiment, the rats were weighted again and anesthetised. Then blood samples were taken from their hearts to determine the serum levels of estrogen, progesterone, and gonadotropins. Their ovaries were removed and ovarian volume, follicular diameter, number of each follicle type, and oocyte volume were determined. Results indicated that MoO 3 nanoparticles strongly reduced body and ovarian weights in the rats. Moreover, a significant decrease was observed in ovarian volume, the number of follicle types, oocyte volume and follicular diameter. The nanoparticles increased the number of atretic follicles via ovarian tissue structure. MoO 3 nanoparticles decreased serum estrogen level and increased serum level of FSH that was associated with disruption in the regulation of progesterone and LH secretion. The findings showed that MoO 3 nanoparticles could bear negative effects on ovarian structure and function.
