Zusammenfassung:Antibiotic resistance is widely acknowledged as one of the most challenging global crises at hand. Antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) are ubiquitously detected as emerging biological contaminants. Several human lives are currently perished due to untreated infections for the emergence of antibiotic resistance. Semi-metabolized antibiotic residue from human faeces and effluents of the pharmaceutical industry are released into municipal wastewater. This in turn triggers the selection of ARGs and ARB, which eventually seek a way into natural environmental matrices. To this end, the unique physicochemical properties of nanomaterials, such as enormous surface area and higher surface reactivity, benefit them to get nominated as an emerging tool to combat antibiotic resistance. As such, tremendous research and development efforts are currently underway to achieve meaningful progress in the development and deployment of innovative nanotechnology-based treatment strategies with high removal efficacy for ARGs and ARB. Nano-enabled water/wastewater treatment system offer perquisites of being energy efficient, effectual, durable, and cost-effective. Although nanotechnological approaches are gaining momentum, the major challenge in terms of commercialization is that long term efficacy of nano-based treatment under realistic conditions remains relatively unknown. This review is intended to accentuate the potentiality of nanotechnology and nanomaterials in ARGs and ARB removal. Additionally, several noble detection technologies that are currently in use as well as those that are in the process of deployment beyond the laboratory scale are enumerated.
