The production of genetically modified (GM) crops is rapidly increasing every single year worldwide. The safety and quality evaluation of these crops is an important issue regarding to consumers’ health. This led the regulatory authorities to implement a set of very strict procedures for the approval to grow and utilize GM produce. Therefore, for fulfilling regulatory compliance on GM labeling ...

We conducted this study to determine efficacy of Parasight-F (an HRP-II antigen dipstick method to detect P. Falciparum) in children. A total of 30 children were enrolled in the age group of 2 months to 12 years whose peripheral smear showed asexual forms of Plasmodium falciparum. All patients were tested for presence of HRP-II antigen of Plasmodium falciparum in their blood by the Parasight-F ...

A dipstick dye immunoassay (DDIA) was developed to detect immunoglobulin G (IgG) or IgM antibodies of toxoplasmosis infection in humans. The assays employ a blue colloidal dye particles (D-1) conjugated to sheep anti-human IgG and rabbit anti-human IgM as the visualizing agents and a soluble antigen of tachyzoites of Toxoplasma gondii strain RH (TSA) as the detective antigen. The mixture of dye...

Aptamers are single-stranded nucleic acids that can be selected from a large random library to bind a number of molecules with high affinity and specificity. Therefore, they are considered to be the nucleic acid version of antibodies. Since its first discovery in the early 1990s, the use of aptamers for sensing and diagnostic applications has been extensively explored. Many detection methods de...

Developing a convenient detection method for dopamine holds significant incentive due to its high clinical significance. Herein, we synthesize crystalline MnOOH nanowires (MNWs) via simple solvothermal treatment of KMnO4 and demonstrate that they possess excellent oxidase-like activity owing the presence pure Mn3+ sites on MNWs. Particularly, MNWs catalyze rapid oxidation into aminochromes, whi...

Microscopy has been the traditional reference standard for malaria diagnosis. However, difficulty in maintaining the required technical skills, particularly in areas where malaria is not endemic, has prompted the development of rapid nonmicroscopic diagnostic assays based on the detection of malaria parasite antigen in whole blood. In this study, we evaluated the performance of one such device,...
