PATHOGEN DETECTION VIA GRAPHENE OXIDE-BASED IMMUNOSENSING: DETERMINATION OF BACTERIA IN INDUSTRIAL SAMPLES OF FOOD

"One of the major concerns of the food industry is the pathogenic bacterial contamination because it represents a risk to health of the consumer, it could cause several diseases and even death.1 E. coli is a bacteria found in environment, foods and intestine of people or animals. Most E. coli s...
