Aptamer based biosensors for detection of Staphylococcus aureus

Abstract

Staphylococcus aureus (S. aureus) is most common causes of hospital-acquired infections and food-associated disease, also staphylococcal food poisoning (SFP) are known as the one of the most important foodborne illnesses worldwide. Many different methods have been developed for the detection and quantification of S. aureus and Staphylococcus aureus enterotoxins (SEs). But most of these methods are usually time-consuming and need complicated sample preparation steps. Therefore, it is of great interest to develop a rapid, simple, and sensitive detection method. In the last years, aptamers, are used as a new biosensor platform for detection of S. aureus in different samples. In this review, recent advances and applications of optical and electrochemical aptamer-based biosensors for the detection and quantitative of S. aureus and enterotoxins in details have been discussed.
