Simple, inexpensive, and high sensitive Lateral Flow Immunoassay (LFI) based colloidal gold nanoparticles antigen-coated as the label was designed for the fast determination of organophosphorus pesticide in cow’s milk samples. The developed LFI detection strip consisted of four structural zones start from the sample pad, conjugate pad, detection zo...

6  Abstract-Titanium dioxide (TiO2) nanoparticles (NPs) colloidal that have been synthesized via Nd-YAG laser technique in pure distilled water. The produced NPs were characterized by UV-Vis absorption spectrophotometer and Transmission Electron Microscope (TEM). The surface Plasmon resonance of the colloidal determined by UV-Vis absorption spectr...

Background: Dermatophytes are a pathogens that can cause fungal infection (Dermatophytosis), and Trichophyton rubrum (T.rubrum) is one of them. It infects superficial layer of the human tissues such as skin, hair and nails. Objective: This work was carried out to study the antifungal activity of TiO2 nanoparticles (TiO2 NPs) which have been prepare...

... In fact, interactions with membranes and any harm caused by these interactions are more apparent in nanoparticles with a positive zeta potential and a small diameter [11]. Zeta potentials were used as a tool to investigate the modification of bacterial cell surface permeability and maybe bacterial membrane penetration and subsequent bacterial viability [12][13][14][15][16]. ...
... Based on results obtained from the graphs, the ratios 1:1 and 1:2 were the most effective at removing E. coli and S. aureus, respectively. It Should be noted that S. aureus is more susceptible to excess zinc oxide nanoparticles in ratio 1:2 42,43 and also E. coli is more susceptible to titanium dioxide nanoparticles in a ratio of 1:1 44 indicates that increasing contact time from 50 min to 100 min at the same concentration (2 mg/mL) and a ratio of (1:1) cause a decrease in the number of colonies from 550 CFU/mL to 0 CFU/mL (Table. 2, runs 4 and 22). ...
