Singapore: A new research promises to detect Ebola, yellow fever or dengue using a paper based testing device. The new method will aid early diagnosis, thus promising faster recovery and will also help in preventing the spread of the disease.
Lead researcher Ms Kimberly Hamad-Schifferli said that traditional methods like PCR and ELISA are highly accurate but they need controlled lab environment, expensive equipment and specialized conditions.
She mentioned that paper device worked similar to over-the-counter pregnancy tests and is a complementary technique to efficiently detect pathogens in places with no running water or electricity.
The researchers attached red, green or orange nanoparticles to antibodies that specifically bind to proteins from the organisms that cause Ebola, dengue or yellow fever, respectively.
They introduced the antibody-tagged nanoparticles onto the end of a small strip of paper. In the paper's middle, the researchers affixed "capture" antibodies to three test lines at different locations, one for each disease.
