New Delhi, (India Science Wire): E.coli is the most common foodborne bacteria causing illnesses including diarrhea, fever, and death if left undiagnosed and untreated, which makes its detection most important. Traditional detection methods such as culture or PCR are time-consuming and require skilled manpower. Antibody-based ELISA tests have also been developed but the instability of the antibodies, high cost, batch to batch variation, and complex synthesis method limits its application. A team of researchers at DBT-National Agri-Food Biotechnology Institute (DBT-NABI), Mohali, has come up with a solution. They have developed a probe based on ssDNA aptamer. Aptamers are low molecular…
