Aptamer-Based Biosensors for Antibiotic Detection: A Review

Abstract

Antibiotic resistance and, accordingly, their pollution because of uncontrolled usage has emerged as a serious problem in recent years. Hence, there is an increased demand to develop robust, easy, and sensitive methods for rapid evaluation of antibiotics and their residues. Among different analytical methods, the aptamer-based biosensors (aptasensors) have attracted considerable attention because of good selectivity, specificity, and sensitivity. This review gives an overview about recently-developed aptasensors for antibiotic detection. The use of various aptamer assays to determine different groups of antibiotics, like β-lactams, aminoglycosides, anthracyclines, chloramphenicol, (fluoro)quinolones, lincosamide, tetracyclines, and sulfonamides are presented in this paper.

Keywords: ampicillin; antibiotic; aptamer; aptasensor; biosensor; chloramphenicol; ciprofloxacin; danofloxacin; daunomycin; enrofloxacin; gentamicin; kanamycin; lincomycin; neomycin; ofloxacin; oxytetracycline; penicillin; streptomycin; sulfadimethoxine; tetracycline; tobramycin.
